Why is the toilet bowl wet? Condensation on the toilet bowl: causes and remedies. Creation of internal thermal insulation

The question of how to get rid of condensate on the toilet bowl arises quite often. First of all, it is important to understand what this phenomenon is and what it can threaten in the future.

Then you should understand what provoked the appearance of water droplets. In most cases, the cause is a broken component or insufficient ventilation in the bathroom, resulting in elevated level moisture.

It is not always necessary to take serious measures to eliminate condensate. In some cases, it is enough to make minor changes to reduce the volume of condensed liquid.

What is condensate

In the general case, condensate is a water sediment that arises from the air and settles on various surfaces. As a rule, it appears due to a sharp change in temperature.

Often a similar phenomenon can be observed after taking a shower on the walls of the booth and other objects, however, such moisture evaporates within a few minutes. But if thin streams of water constantly form on the toilet bowl or pipes, this is a problem and certain measures must be taken to eliminate it.

Note! Condensation on the toilet bowl is formed due to the effect of cold water (temperature 8-16 degrees) on the surface of the tank from the inside, as well as the influence of warm air flow (temperature 26-30 degrees) on the outer wall. Due to the large temperature difference, the humidity rises and sediment appears.

Why does condensation appear on the tank

There are a few basic conditions to check to determine why condensation is forming on the toilet cistern:

  • frequent operation of plumbing equipment, as a result of which water in cistern does not have time to warm up to room temperature. In the presence of a large number residents, the use of the toilet occurs at short intervals, which contributes to the constant appearance of condensate;
  • a drain malfunction, due to which the heated water is drained, and the deficiency is filled with cold liquid from the water supply. Malfunctions of the shut-off valve or other fittings are sufficient common cause condensate on the toilet bowl;
  • high humidity in the bathroom. For example, clothes are sometimes dried in the bathroom, as a result of which the air is filled with moisture, but it cannot evaporate from plastic and earthenware surfaces, so a water precipitate forms on them;
  • lack of sufficient ventilation of the room. In some cases, home owners decide to completely close the ventilation window during the construction and renovation process. However, this disrupts the circulation of air currents and increases humidity, so there is strong condensation on the toilet tank;
  • the location next to the plumbing of various heating appliances or a pipeline with hot water.

What threatens the accumulation of condensate

How urgently it is necessary to solve the problem and whether it is required to solve it at all, each landlord decides on his own. In some cases, fogging of the drain tank is not a permanent phenomenon, i.e. the condensate has time to dry.

In such a situation, there is no need to worry, because. it will not lead to any serious negative consequences. However, in the presence of a constantly wet tank, you need to think about how to get rid of sediment. The trickles that run off form puddles on the floor that need to be cleaned up regularly. Such a problem can bring significant inconvenience to the owner of the apartment.

  • Install an air dryer. This device will collect water molecules in the air and localize them in a separate container. The device operates on the basis of the indicators of the built-in hygrometer. When choosing, consider the size of the bathroom.

Such actions in most cases lead to the prevention of a situation where condensate accumulates on the toilet bowl.

Rise in water temperature

For insulation, in some cases, foam is used. It has excellent thermal insulation properties, but involves a more complex process. It is advisable to apply the foam in 4 stages to ensure uniformity.

Then you will need to wait a while until it is completely hardened, after which you can cut off the excess part. For high-quality insulation, a layer one centimeter thick is sufficient.

Drain structure repair

If the toilet tank is constantly leaking, then the water in the tank does not have time to heat up, resulting in the formation of condensate on the surface.

If the shut-off valve is broken, the rubber bulb has lost its elasticity, or the rubber seal has ceased to perform its functions,. This situation can lead to up to 2-3 liters of condensate per day.

The answer to the question of how to deal with condensate on the toilet bowl in this case is the replacement of non-working parts. As a rule, broken components cannot be repaired, so it is better to purchase new ones.

ADVICE! When choosing, it is important to focus on the model of the toilet or cistern, because. otherwise, the purchased parts may not fit in size, and the problem will persist.

In the process of installing a new drain system, it is advisable to follow some rules:

  • get rid of lime deposits in the holes;
  • change the seal (rubber gasket);
  • plastic nuts are best tightened by hand, but not very tightly. The use of metal tools and tight fastening can lead to breakage of fasteners. The wrench should only be used if there are metal bolts in older models;
  • Reducing the volume of drain

    If the plumbing is used by a large family, then the water will be washed off often, which will lead to the fact that the collected liquid will not have time to heat up. In this case, reducing the volume of drained water will help to get rid of condensate.

    How to eliminate condensation on the toilet bowl:

    • set the half drain button. You can do this yourself by adjusting the shut-off valve mechanism, or install a new tank;
    • install a double start / stop button, which will allow you to control the volume of the descent fluid.

    If this is not possible, it is advisable to purchase an upgraded tank with a button that helps minimize draining.

    The question of how to remove condensate from the toilet bowl often worries apartment owners. If sedimentation is rare and moisture has time to dry, drastic measures are not required.

    However, in other cases, it is important to take care of how to get rid of condensate in a timely manner. There are several options for solving the problem, the appropriate one is selected based on what caused the problem.

The appearance of condensation on the toilet cistern is a rather unpleasant phenomenon. Condensation accumulates, covering the entire tank with drops. Drops roll down, forming a wet spot around the toilet. And such dampness is not at all harmless.

Fungal spores, easily carried through the air, contribute to the development of pulmonary diseases in those who live in such an apartment. Once in the body, spores cause the appearance of lesions of the respiratory system up to pulmonary edema.

Why does condensation collect on the tank?

As is known from the school physics course, the air around us contains water vapor, the amount of which directly depends on temperature.

The transition of moisture from water vapor to liquid droplets occurs when the temperature of heated moist air decreases. We see this when condensation appears on the bathroom mirror, when glasses fog up in winter, entering a warm room from the street, and also in many other cases.

How to get rid of condensation?

There are several ways to deal with condensate on the walls of the tank, pipes and other surfaces.

To establish ventilation, if it does not work well, is not so difficult. To improve the operation of the hood in the bathroom or bathroom, you can install a small axial fan that provides forced ventilation and removal of heated moist air from the room to the ventilation duct and then to the exhaust stack of the building's ventilation system.

The fans produced today are characterized by low power consumption and ease of installation, which allows you to install it in a matter of minutes, even if you do not have experience in such work.

When choosing a fan, you should first of all pay attention to its performance. In accordance with modern sanitary norms and rules, air exchange in the amount of 25 cubic meters per hour should be provided in such premises.

Installing a double cistern toilet

A very effective way to get rid of the appearance of condensate on the toilet bowl is to install a double tank.

Installation of fittings with double drain

To reduce the amount of cold water from the water supply entering the tank and cooling its walls, you can install a drain valve with a double drain.

Adjusting the cistern flush valve

The most common cause of condensation on the toilet is water leakage, when water constantly flows in the toilet in a thin stream.

Such leakage leads to the fact that the water in the tank does not have time to heat up, constantly replenishing with ice water from the water supply system, it greatly cools the toilet tank, on the walls of which condensation forms from contact with warm air.

In this case, the flush fitting will need to be adjusted to stop the constant flow of water.

  • replacement of sealing gum;
  • adding a small weight to the valve to improve its fit;
  • softening the rubber of the valve by pouring boiling water over it (it helps only for a while, as a temporary measure);
  • thorough cleaning of deposits on the elastic band and on the valve with a vinegar treatment.

Adjusting the float valve is also not particularly difficult and consists in setting it to close when water is drawn in to the desired level so that it does not flow through the overflow. An overflow is a hole in any flush fitting that allows you to dump excess water entering the tank into the toilet in case of a malfunction of the float valve.

Another reliable way to stop the constant wetting of the cistern from condensate falling on it can be to replace a conventional compact toilet with a ceramic cistern installed on it with an installation.

In addition to improving air exchange and adjusting the drain fittings in the bathroom, to reduce the amount of moisture accumulating on the tank, you should follow some rules.

Getting rid of condensation on the toilet bowl

Many owners of urban apartments are faced with the problem of moisture on the surface of the drain tank. If nothing is done, then the moisture flowing onto the floor will soon seep through the flooring and seep into the apartment to the neighbors. Also, the runoff of moisture will lead to the appearance of limescale on sanitary fixtures. How to get rid of condensate on the toilet bowl, homeowners are perplexed - we will consider the answer to this question in our article.

The main causes of occurrence

According to experts, drizzle on the toilet cistern appears in late autumn or winter. The reason for this phenomenon is considered to be a sharp difference between the temperature of the water in the plumbing system and the indoor air. If in the supply pipes the temperature of the liquid is in the range from 3 to 5 degrees Celsius, then in the bathroom such indicators increase to 18-22 degrees. If there is high humidity in the room, dew drops will appear on the surface of the tank filled with cold water. Moisture condensation will occur with the same intensity on cast iron, ceramic or plastic plumbing fixtures.

Explain why condensation occurs winter period pretty simple. At this time, the water vapor in the air quickly turns into a liquid form, usually this happens when the air temperature in the room decreases. It is completely impossible to get rid of drizzle, but it is quite possible to reduce its influence.

The main reasons for the appearance of water droplets on the drain tank are as follows:

  • failure of the shut-off valve, as a result of which the tank will be constantly filled with cold water coming from the water supply. Non-standard operation of the locking mechanism can be easily identified by a thin stream of water that flows down the surface of the toilet. Such accidents lead not only to the appearance of drops of moisture on plumbing, but also to water overruns;
  • also, condensate may appear as a result of frequent drains, which leads to the complete emptying of the tank. Modern plumbing fixtures are usually made with thin walls that cool quickly;
  • improper operation of the ventilation system;
  • misuse of the premises.

Repair of the locking mechanism

First you need to take care of the proper operation of the drain mechanism. In winter, dew drops appear on the surface of the tank all the time, but improper operation of the drain system will enhance this effect and can lead to irreparable consequences.

The main cause of failure is the destruction of the material of the drain seal or intake mechanism. In this case, the water from the tank will constantly drain into the sewer system, while the tank is constantly filled with cold liquid from the water supply. As we have already said, up to 2 liters of liquid per day can drain onto the floor, but the amount of condensed moisture can be reduced by installing new seals.

cistern design diagram

Before installing the drain system, get rid of limescale on the surface, install new gaskets. To prevent deformation of the seals, the fixing nuts are tightened by hand. With a wrench, only the metal clamps that pass through the bottom of the tank are tightened, but such products are used only on older plumbing fixtures.

Partial elimination of condensate by reducing the volume of the drain tank

The appearance of dew on plumbing can be prevented by reducing the volume of drained liquid. It will not be possible to completely avoid the appearance of condensate, and especially with frequent use of the toilet. In this case, the tank will be constantly filled, as a result of which the liquid will not have time to heat up to the desired temperature. The difference in temperature fluctuations will lead to the appearance of moisture on the surface of the tank.

To solve the problem, it is recommended not to completely drain the water in the tank, which can be achieved by using the half-release button. The second way out of this situation is to install a plastic bottle filled with liquid in the tank. Another option to solve the problem is to replace the drain mechanism with a more modern model.

Prevention of temperature fluctuations

Using this method allows you to completely get rid of the formation of condensate on the surface of plumbing. Dew drops will not appear on the surface of the tank when the temperature of the liquid coming from the water pipe matches the temperature inside the room. In this case, moisture condensation will not occur if the drain system breaks down.

Summer tap water heats up during passage through the piping system, at the inlet to the toilet bowl the temperature of the liquid is similar to the air temperature in the room, which will prevent the formation of condensate. In winter, the supply pipeline is insulated or heated using a special heater equipped with a thermostat. The device is set to room temperature. The second solution to the problem is cooling the air in the bathroom or toilet.

Reducing air humidity

The correct operation of the ventilation system will help to reduce the humidity of the air, because excess moisture will be removed into the hood. Some homeowners tightly close the vents in the bathroom, which will be the main cause of condensation. The first step is to check the operation of ventilation.

If the ventilation system does not function properly, it is necessary to clean the channels. If this does not help, contact the appropriate service. In small bathrooms, where a significant amount of moist air accumulates, a forced air duct is installed. Constant air circulation in the apartment can be provided by installing several through holes in the doors of the bathroom or toilet.

Toilet ventilation scheme

Using a double wall tank

Similar tanks are equipped with the latest models of toilet bowls. Such products are much more expensive than conventional plumbing fixtures. Structurally, the new tank consists of an air gap body and a plastic container that is filled with water. Such a solution allows you to nullify the difference between the temperature of the incoming liquid and the air temperature inside the room.

  • drain the water from the tank;
  • you can remove it, it will be easier;
  • dry;
  • stick Izolon from the inside over the entire surface of the tank.

Why does the toilet cistern sweat and how can condensation be eliminated?

Condensation falling out on the toilet bowl puzzles many homeowners. Due to the constantly flowing water droplets from the surface of the drain tank, puddles form on the floor, which must be wiped up in a timely manner. Otherwise, dampness will lead to mold and bad smell. Of course, you can adapt some container to collect water, and then do not forget to empty it of the contents in time. Many housewives do just that, trying to solve this problem in this simple way. Men try to find out why the toilet cistern is sweating in order to eliminate the cause and forget about the problem forever. Are there effective ways to deal with condensate that periodically appears on the toilet bowl? Let's figure it out.

Causes of condensation on the drain tank:

  • High level of humidity in the bathroom and in general in the whole apartment. High humidity can be caused by a large number of indoor plants, drying a large amount of wet laundry, leaking plumbing pipes or heating systems, and other factors.
  • The incessant flow of cold water into the toilet bowl for a second due to a malfunction of the valves, as a result of which the water does not have time to warm up to room temperature.

To understand why the toilet bowl is sweating, you need to remember a little school course physics. The contact of warm and moisture-saturated air with cold surfaces inevitably leads to the appearance of water droplets on them. This means that it is necessary to look for ways to dry the air, as well as to increase the surface temperature of the drain tank.

Checking the condition of the vents

To reduce the level of humidity in the air, it is necessary to adjust the ventilation of the bathroom. Each apartment has special ventilation "windows" that provide air circulation. In pursuit of the beauty of the interior, some residents seal these holes with finishing materials, which, of course, is unacceptable.

To mask ventilation windows, you need to buy decorative grilles that are specifically designed for this purpose. They can be selected in terms of color, shape, and design. Before installing decorative grilles, clean the ventilation ducts from debris.

Installing a fan that turns on when the light is turned on will help partially solve the problem of condensation.

Air ventilation in the room can be organized even more efficiently if you connect a forced ventilation system. To calculate the power of the ventilation system, you must contact the experts. After assessing the condition of the bathroom and the intensity of its operation, professionals will give recommendations on the choice of equipment.

Repair of faulty valves

If the mechanism of the drain device breaks, then the water in the toilet flows without stopping. This leads to the constant replenishment of the tank with cold water, which reduces the temperature of its surface. In this case, the condensation process is ongoing. The problem can be eliminated only during the repair of valves or its complete replacement. To carry out repairs on their own or invite a plumber, each homeowner decides independently, based on the financial capabilities of the family.

In addition to partially eliminating the problem of condensate, repairing the drain mechanism of the tank will save water consumption. This is especially true for owners of those apartments in which metering devices are installed - water meters.

Double wall cistern

Manufacturers of modern toilets are aware of the problem of condensation and offer their own effective solution. The latest models of toilet bowls are produced with an improved design of the drain tank, which does not allow them to “cry”.

The double-walled flush cisterns of today's toilets never sweat.

In these models, an additional plastic container is inserted inside the tank, the walls of which do not come into contact with the ceramic surface of the product. As a result, its temperature is always constant and equal to room temperature. This constructive solution allows you to solve the problem once and for all. However, for many buyers, these models are still inaccessible at a cost that is several times higher than the price of conventional toilet bowls.

Some amateur craftsmen try to isolate the walls of the tank from exposure to cold water using heat-insulating materials that are glued to them from the inside of the tank. However, this technology does not completely solve the problem of condensate.

Some amateur craftsmen are trying to deal with condensate on the tank by pasting its inner walls with heat-insulating material

If expensive "non-crying" models are still too expensive for you, then try installing forced ventilation. Even a simple fan inserted into the ventilation window and turned on when the light in the bathroom is turned on will solve the problem of condensation on cold surfaces. If after that the toilet bowl sweats, then call specialists to install more powerful ventilation systems.

Why the toilet cistern sweats and how to eliminate condensate


Why is the toilet cistern sweating? possible reasons. How to get rid of condensation on the toilet bowl? An overview of two ways to solve an urgent everyday problem.

Condensation on the toilet bowl - how to get rid of it?

About the formation of "dew" on the toilet bowl - a problem that occurs in the winter in almost every apartment. The consequences can be different - from small drips and a slight increase in humidity in the bathroom or bathroom to the formation of puddles on the floor, the reproduction of mold spores. You can avoid unpleasant consequences by eliminating the condensate on the toilet bowl in advance, how to get rid of which you will learn from this article.

Condensation on the toilet bowl

Why do water streaks form?

  • Ventilation failure

The cause of condensation may be a malfunction of the ventilation system or the absence of a ventilation window (often closed during repairs in order to improve the interior). As a result, proper air circulation is not ensured, and excess moisture settles on surfaces.

Ventilation is a mandatory attribute of a modern apartment

  • Increased humidity level

The location of the bathroom in the bathroom, constant drying of wet clothes in the apartment, leaking pipes, a large number of plants in the house cause an overestimated concentration of moisture in the air. If it simply evaporates on pipes, then it settles on plastic and ceramic surfaces, forming drops. On the pages of our portal you can also find out how installing a toilet on a tiled floor and why it matters.

High humidity is the main cause of condensation

  • Temperature difference

Water for internal filling of the tank is collected from a centralized network. Its temperature is 3 - 5 °C in winter. Outside air in the room can reach 25 °C due to the placement of heating pipes. A difference of 10 - 15 °C is sufficient for condensation to form.

  • Drainage device failure

A malfunction of the valves leads to the constant filling of the tank with cold water, which goes into the sewer without having time to warm up.

When the toilet cistern breaks, cold water does not have time to warm up

  • Excessive water consumption

A similar phenomenon is observed with frequent use of the drain, especially in large families. In addition to cost, this leads to a stable maintenance of the difference between the temperature outside and inside, therefore, to the appearance of condensate.

Having established the cause of the appearance, consider how to get rid of condensate on the toilet bowl.

Normalization of air circulation

First of all, check how efficiently natural ventilation works. Windows for ventilation should be closed with a grate, in no case clogged with dirt and dust.

Natural ventilation - the key to protection against high humidity and mold

Many users prefer to leave open door into the bathroom, but a better option is to make a gap at the bottom.

To improve air circulation, arrange a ventilation grill in the bathroom door.

Before installing decorative nets, the channel should be cleaned of debris, if this has not been done, then there is a possibility that there is no draft in the system. In this case, it needs to be cleaned. In a private house, this responsibility falls directly on the owner, in multi-storey residential buildings - on the service housing office, where you should contact.

Natural ventilation is not always provided by ventilation. In this case, you should install an artificial one. It is difficult to do this on your own, since you need to take into account the power of the equipment and the state of the microclimate of the room, so we recommend contacting special centers.

In case of poor-quality natural ventilation, it is necessary to organize forced ventilation

There are also systems that dry the air, which are focused on joint bathrooms. They provide a decrease in the degree of humidity, utilizing water vapor.

Alignment of the temperature balance

To achieve approximately the same water temperature in the tank and the room, there are two ways.

  • Decrease in air temperature

Usually the problem occurs in the winter, so the first method is not always practical. You can get results by lowering general temperature in the system, but then the house will become a few degrees cooler. This has its advantages, because you can save on heating.

A decrease in air temperature helps to equalize the temperature balance

With a centralized system, this will not solve the problem. You should take care of the thermal insulation of pipes near the bathroom, and also make sure that the doors to the room are closed.

  • Incoming water heating

If possible, it is recommended to connect a pipe with hot water to the tank. The tank will automatically fill with liquid at room temperature, and the likelihood of condensation will be reduced to zero. The best option is to install an electric heater on the tank.

We install an electric heater to increase the temperature of the water

Repair of shutoff valves

Condensation that forms on stable toilets is not so terrible and is eliminated much easier. In systems whose drain mechanism is damaged, this phenomenon becomes permanent, because the tank is constantly replenished with cold water.

To avoid condensation, all fittings must work properly

Gravity flow can be determined by the noise of flowing water or visually: the jet does not stop after filling the tank, the tank is filled for a very long time and is not completely filled.

  • the humidity in the room increases even more;
  • puddles form on the floor;
  • dampness leads to mold;
  • an unpleasant odor occurs.

Condensation on the toilet bowl how to get rid of?

In this case, neither ventilation nor air drying will be able to get rid of the problem completely. Gravity can be eliminated on your own, but if the breakdown is serious, it is recommended to call a plumber.

If the reason for the constant filling of the tank, therefore, the inability of the water to warm up, is the frequent use of the toilet, for example, in a hostel, the water flow should be monitored when draining.

Frequent use of the bathroom also causes condensation.

New systems are equipped with a "partial" drain button, which allows you to use half the tank. Old toilets do not have this function, but you can replace the fittings by installing a more economical one.

Installation of a universal tank

Modern systems exclude the appearance of condensate in advance by equipping toilet bowls with double-walled cisterns. A plastic container is placed inside the main body, there is no contact with the ceramic walls, so they remain dry.

In search of a solution to how to get rid of condensate on the toilet bowl, some users try to “isolate” the tank on their own by pasting the walls with protective materials inside or out. The first is not always effective, besides it reduces the volume of the tank, the second spoils the aesthetic appearance, and sometimes harms the surface coating.

Following the suggested tips will help you get rid of the "wateriness" on the tank, as well as improve the microclimate of the bathroom.

Condensation on the toilet bowl how to get rid of the cause?


Condensation on the toilet bowl becomes a sore problem for many in the cold period, how to get rid of which you can learn from this article.

Drops of liquid, and sometimes large streaks on the flush tank in the toilet, are not uncommon. Gradually accumulating on the floor, such moisture needs frequent cleaning, in addition, condensate on the toilet bowl leads to corrosion of water pipes (with old plumbing). Also, the formation of fungus, mold and constant humidity becomes a problem, as a result - a specific smell in the bathroom room.

So what is condensate? This is moisture that appeared from the influence of cold water with a temperature of 6-10 degrees on the surface of a ceramic tank on one side (internal) and room air, having a temperature of 20-24 degrees, acting from the outside. To eliminate this trouble, you need to understand the cause and know how to eliminate it.

Most often, there are two reasons: humidity in the bathroom and a large temperature difference between the surface of the drain tank and the surrounding air.

Condensation forms at the "border" of warm and cold air, so a 12-15 degree difference between the walls of the tank and the air environment is enough to form moisture.

The source for the increase in humidity and the difference in degrees can be such phenomena:

  • Lack of proper ventilation in the bathroom;
  • pipe failure;
  • a riser in a room with constantly circulating water;
  • hanging clothes to dry;
  • malfunction of the shut-off valves of the tank, due to which increased water consumption;
  • penetration of air with increased dampness from the street through cracks in door or window openings;
  • marriage made during finishing work: waterproofing of walls or ceilings that does not meet standards, illiterate installation of double-glazed windows.

And also the primary source and reason why the tank “sweats” can be a combined bathroom with a bathtub.

Tank valve failure

Condensation can accumulate on the surface of the tank due to the incessant supply of cold water, because the drain mechanism is faulty. This leads to filling and into the toilet, thereby, due to cold water, the temperature on the surface of the walls of the tank decreases.

There is only one way out - repair of component parts or replacement of all fittings. In addition to eliminating condensate, repairing the drain tank device will save a lot of water. This is especially important for users who have water meters.

Consequences of condensation

The constant presence of moisture on the surface of the drain tank is not only a small nuisance - it is a big problem that in a few years can cause a lot of discomfort for the family to live well.

This is fraught with the following consequences:

  • The microclimate is deteriorating;
  • condensate contributes to the occurrence of corrosion on metal elements;
  • any cosmetic repairs made with expensive materials will be reduced to zero due to prolonged exposure to moisture;
  • mold and fungus will appear in the room.

And if you leave the bathroom unattended for a long time, then puddles formed from condensate can penetrate to the neighbors on the lower floor. And this already threatens not only with spoiled relations with them, but with possible financial costs for repairs.

How to get rid of condensation on the toilet bowl?

There are several options and ways to eliminate this phenomenon.

Tank modernization

Often the formation of condensate is eliminated by various manipulations with the drain tank:

  • Method #1. Repair of the locking mechanism inside the tank. Due to an incorrectly adjusted float, the valve does not close and there is an endless circulation of cold water.

Note: With frequent draining of water, and, accordingly, filling the tank, an increased amount of condensate also forms, since cold water does not have time to warm up to room temperature.

  • Method #2. Replacing a conventional tank with a double wall cistern. This is the most reliable option, but it is not acceptable for all users due to the high cost.
  • Method #3. And now special plastic liners made in the shape of a tank are sold in stores. It remains only to insert them inside the container, while the flushing and water inflow mechanisms can be left out.

Double wall cistern

The manufacturers of today's toilets understand the problem with condensation and recommend their own options. Now on the market there are many different models of plumbing fixtures with a modified tank design that prevent them from getting wet.

The improvement lies in the manufacture of products with double walls. It practically reduces the formation of moisture on the outer surface of the tank to zero. Such a drain tank is equipped with a special plastic tank inside.

Attention! Plastic has low thermal conductivity, and besides, its walls have little contact with the inner surface of the ceramic tank. As a result, the temperature of the faience tank is constant.

Thanks to this design with a built-in tank inside, there is no liquid left on the walls of the external faience tank.

Thermal insulation of the tank yourself

Some home craftsmen isolate the tank from the influence of cold water due to insulation, which is glued from the inside of the tank.

For this they use:

  • foamed polyethylene 6-8 mm thick
  • silicone sealant
  • glue waterproof
  • stationery knife
  • roulette
  • wrench and socket wrench 10 mm.

For these purposes, tepofol, foamed polyethylene, polystyrene, etc. are used. effective method removal of "fogging" on the tank. The basic rule to follow
it is to use a material with a thickness of no more than 10 mm, otherwise the volume inside will noticeably decrease.

In order to carefully isolate the walls of the faience container, it will be more convenient to remove it and remove all internal fittings. Rinse and dry the tank. Then prepare patterns. In order not to be mistaken in size, it is easier to cut and fit first on thick cardboard, and then transfer it to the insulation.

Glue the workpieces to any waterproof glue, and coat the joints with sealant, and insulating material must be applied not only to the wall, but also to the bottom of the tank. After drying, install the container, assemble the fittings, turn on the water and put the upgraded product into operation.

Another option for insulation can be external insulation. But at the same time, it must be borne in mind that it is easier to glue the heat-insulating material without gaps from the outside, but it is more difficult to arrange aesthetics.

Therefore, you can buy a compact toilet bowl with a tank, which is installed in a wall niche. And then it can be insulated with any material, and then closed with a cladding. But this is an off-budget option, and it is not suitable for everyone.

half flush

A good way to eliminate condensate is to mix cold and warm water (this option is possible in autonomous heating systems).

The second similar solution to the problem would be to use the descent of half the volume of water by double pressing the button or using the second key.

Changing the microclimate of the room

Along with measures that act to remove condensate in a bathroom or with a shared bathroom, a variant with a change in the microclimate is used. This includes natural or artificial ventilation. If there is a gap at the door or window, then you can not think about the inflow.

It is only necessary to check the hood in the ventilation duct. To do this, just bring a match or a lit piece of paper. If the flame does not deviate towards the passage, then there is no thrust, and then you need to try to figure out the reason: the grid is dirty, the channel is cluttered, etc.

At the same time, we must not forget that the natural hood in the bathroom should be large. Undoubtedly, the lower the speed of air movement, the larger the cross section must be for the well to exit. And no one will refute that in forced ventilation, air exchange occurs faster.

This rule is reflected even in the SNiP standards: the air speed for a conventional hood should be up to 1 m³ / h, and for forced ventilation - from 2 to 4.5 m³ / h. Therefore, for the same area of ​​\u200b\u200bthe room, the dimensions of the ventilation wells should be different.

For example, to transfer an air flow with a volume of 300 m³ / h, you need:

  • with forced circulation - a well with a size of 170 × 200 mm;
  • with a simple hood, it should already be increased to a section of 260 × 400 mm.

Thus, if all attempts to restore the natural exhaust in the toilet failed, then you need to set up forced ventilation.

Air dryers

Another way to reduce the level of humidity in the bathroom is to install a dehumidifier. It absorbs excess moisture, while it is collected in a tray located below.

Moreover, the device works until the required humidity indicators in the room are reached. The operation of the dehumidifier directly depends on the readings of the hygrometer mounted inside.

Heating water in a tank

Getting rid of moisture on the walls of the tank, often used to increase the temperature of the water in the tank. In principle, everything is understandable: if there is no difference between the temperatures of the incoming water and the ambient air in the toilet, then there will be no condensation.

In practice, the following options are used to implement this method:

  • Option number 1. Instead of cold water, a pipe with hot water is connected to the drain tank. Even if the temperature of such incoming water is high, then mixing with the water in the tank, it becomes close to room temperature. This solution to the problem is suitable for those users who do not have a water meter installed.
  • Option number 2. Construction of a heat exchanger. To do this, you can use a riser with hot water, which runs inside the toilet. You just need to wrap it around with a copper tube, and put a heater on top. Connect one end of the tube through a tee to a pipe with cold water, and direct the other into a drain tank.

Attention! Water, passing through the coil around the hot pipe, heats up by 3-4 degrees, sometimes this is enough to prevent condensation on the tank.

  • Option number 3. Mount the water heater in the bathroom and make an eyeliner from it.

Forced ventilation

Before removing condensate from the toilet bowl, you first need to create the proper ventilation level in the toilet. This requires two components: the inflow of air from external rooms or from the street and its exit through the ventilation ducts.

In case of insufficient air exchange with natural exhaust, forced ventilation is installed. Fan performance is usually taken according to the average data of SNiP standards. Taking these figures from the table, it can be seen that for the toilet room the air velocity should be 50 m³ / h.

Thus, to deal with condensate, according to experts, it is fundamentally possible in only one way - by creating forced ventilation.

A modern bathroom boasts practicality, convenience and comfort. If you take care of the toilet properly, its appearance and functionality are preserved for a longer period. But when fogging occurs on the toilet tank, it can lead to damage to plumbing fixtures, the appearance of foreign odors and the formation of black mold. How to cope with leaks and eliminate the cause completely?

When, it is necessary to identify the initial cause of the appearance. Usually, it is a high level of humidity in the room. To normalize this indicator, it is necessary to determine the reasons for the increase in the level.

  1. Faulty pipes or plumbing fixtures. Such breakdowns must be eliminated as soon as possible, since ignoring them can only aggravate the situation. Under the influence of moisture, pipes corrode, which leads to unnecessary leaks and flooding of neighbors.
  2. Drying large loads of laundry. This is true for large families and small rooms. In this case, it is recommended to dry things on the balcony (if available), as well as in the yard or in a separate room.
  3. Poor ventilation system. Because of. That ventilation does not properly perform its functions, the air in the room does not have time to be updated in time. From what, the room does not dry out well enough.
  4. The most common cause of toilet sweating can be considered a breakdown inside the tank itself. As a result, cold water flows in a constant mode, not having time to warm up to room temperature in time. That is why the tank starts to sweat.
  5. A large amount of vegetation in the house, requiring moisturizing procedures. Also, the presence of an aquarium affects the increase in the level of humidity in the room. You can eliminate this cause by installing an air dryer.

A prime example of a toilet cistern fogging up

Ways to eliminate condensate

The appearance of dampness, mold and unpleasant odors is far from full list effects of fogging on the toilet cistern. To resolve these shortcomings, it is necessary to take a number of measures to improve the functionality of the premises.

Reducing water consumption

Since large families use the toilet quite often, the amount of flushed liquid should be reduced by adjusting the amount of water supplied. An easier solution to this problem is to purchase a new toilet with a flush that can be adjusted automatically. Also, on sale there are toilet cisterns with an improved flushing system. When the button is pressed for the first time, the water is drained, and when the button is pressed again, the process stops.

Improving the ventilation system

Poor ventilation is the cause of many problems: respiratory diseases, insufficient oxygen, bad smell, humidity in the room.

In order to check the functionality of the air ducts, it is enough to bring a sheet of paper to the air vent. In this way, you can check the quality of the system. If it malfunctions, the walls and floor can be covered with drops of water and fogging, which in turn can lead to the formation of fungus.

Forced ventilation

Installing forced ventilation helps to solve the problem of condensation on the toilet cistern. Many consumers, wanting to decorate the room, close the vent. Under no circumstances should this be done! For such purposes, you can turn your attention to decorative grilles that cover the non-aesthetic appearance of the hole. At the same time, maintaining normal air circulation in the toilet room. Another solution is to install a fan that starts when the light in the room is turned on. And of course, the easiest option would be to leave the door to the restroom a little ajar, in the absence of visitors.

Change in water temperature

Misting on the drain tank is formed as a result of the difference in the temperature of the water and the room. Usually, it varies from ten to fifteen degrees Celsius. By minimizing this difference, you can partially get rid of the condensate.

To do this, it is necessary: ​​to insulate the pipeline, change the source of water from cold to hot, or install a water dilution system.

Drain tank insulation

An example of insulation of a toilet bowl with polyethylene foam

It is possible to insulate the drain tank by placing a plastic structure in it at a distance of no more than two to three millimeters from each other. Between which, you need to install gaskets. Thus, you get a tank-in-tank system. When working, it should be borne in mind that the thickness of the material used should not exceed one centimeter, otherwise the required amount of water will not fit in the tank. When installing insulation, you can use the available means: sealant, glue and mounting foam. It is worth remembering that these works are carried out only after the water is completely blocked, and the tank is freed from all moisture.

Repair of the construction of the drain tank

In the event of a breakdown in the design of the drain tank, it is necessary to pay attention to the elasticity of the pear, the quality of the rubberized elements, and the functionality of the shut-off valve. A used part is best replaced rather than trying to upgrade it yourself. Otherwise, such self-activity can lead to uncontrolled discharge of water into the sewer, as a result of which, the formation of condensate can increase up to two to three liters per day.

Before installing a new system, you should pay attention to a few details: if the nuts are made of plastic, then they must be tightened by hand; do not connect some parts too tightly, this can lead to premature wear of the structure; drain mechanisms should be located in the tank in such a way as to prevent accidental contact with its walls.

Drain control

To reduce the amount of water drained, it is enough to purchase a newer model of the tank. If this option is not possible, then the drain unit can be adjusted manually by setting the valve mechanism yourself.

In addition, installing a double drain button can help solve the problem. At which, pressing one of them will mean draining the water, and the second - stopping the current process.

Home microclimate

To normalize the operation of the drain system, you will need to start with the modernization of the home microclimate. Since, fogging on the toilet cistern may be the result of poor ventilation in the apartment. More specifically, the exhaust air does not leave the room, but lingers, warms up and accumulates, settling on the surfaces of walls and plumbing. If it is not possible to replace the old duct, then the ventilation of the room should be controlled. Moreover, the restroom is a haven for various kinds of bacteria. It is not necessary to improve their conditions for the harmonious arrangement of their existence and reproduction.

Toilet cistern sweating is a common problem for many apartment owners. Sometimes, in search of its solution, the owners correct a number of other possible consequences. Thus, ennobling your home. If the condensate on the tank dries quickly, and its formation is infrequent, then in such a situation there is no reason to panic. Since, the use of radical measures is not required.

Toilet bowl malfunctions and their elimination

If even a thin stream of water flows into the toilet unhindered, then its volume in the tank must be continuously replenished. Hence the water droplets on the surface and high water bills. The solution to the problem is to fix the leak. Sometimes it helps to replace the worn-out rubber membrane of the siphon, for which:

  • water is completely drained from the tank;
  • fix the lever in such a position that the hole is closed by a valve and no more water flows;
  • dismantle the siphon by disconnecting it from the lever;

First of all, you should eliminate possible tank leaks, if any.

  • the worn out membrane is removed and replaced with a new one;
  • return the siphon to its place and fix it;
  • perform a test run.

The reason may be hiding in a faulty float, then perform the following actions:

  • remove the float from the tank;
  • pour water out of it;
  • let dry;

float repair

  • seal the hole through which water enters it;
  • set in place.

If it is possible to buy a new float, then this option is better, because. the repaired part will still not last long. The problem can be solved even easier if the leak is due to the wrong position of the float, in order to fix it, it is enough to open the tank and return the lever to its normal position.

Other Ways to Eliminate Condensation

Never sweaty toilet

Not so long ago, models of toilet bowls with a two-piece tank appeared on sale. The water in it is in an internal plastic tank and does not come into contact with the walls of the main vessel, therefore, condensate does not form. The solution is ideal, but the cost is confusing - it is several times higher than that of a toilet bowl with a traditional cistern.

The device of a two-piece toilet bowl

Drain minimization

The less water goes into the sewer, the greater the chance that there will be no condensate. There are toilet bowls with a tank equipped with a two-button mechanism. When one button is used, approximately 5 liters of water flows out of the tank, the other about 7 liters. And in tanks with an aquastop drain system, one control button is mounted in the lid: with one press, the water begins to pour out, and with the second press, this process can be stopped.

Two-button mechanism for descent of water

Drain tank insulation

Some craftsmen independently isolate the walls of the tank from interaction with cold water. The refinement is as follows:

  1. Turn off the water supply.
  2. Disconnect the hose through which water enters.
  3. Take off the sump.
  4. Dismantle everything inside the tank.
  5. Rinse the container, wipe dry.
  6. Cut out the liner from the insulation. To do this, it is laid out on a flat plane, the tank is placed on it in the same position as it usually stands in the working position, the bottom is circled around the perimeter, and then the workpiece is cut out.
  7. Put the workpiece inside, press firmly.
  8. The height of the walls is measured from the inside, starting from the liner and ending with the upper edge of the tank. Subtract from the resulting size about 3 cm.
  9. The perimeter of the walls is also measured from the inside, an allowance of about 100 mm is added.
  10. Put the pattern inside. The joint is overlapped, therefore, gently pressing the workpiece against the walls, a through cut is made in this place. Take out the blanks.
  11. Perform assembly:
  • apply sealant to the bottom, around the holes for installing fittings;
  • set the bottom in place;
  • insert the inner liner, having previously applied glue to the sidewalls;
  • fill the vertical joint with silicone;

Insulated cistern

  • treat the joint between the bottom and the side walls with a sealant;
  • give time to dry for at least a day, cut holes for reinforcement, apply sealant to the edges;
  • set everything in place.

Here are the main causes of fogging of the toilet cistern and how to eliminate them. If you cannot remove the condensate yourself, contact a professional.

Forced ventilation

In the case when all the necessary actions with the tank have been carried out, and the presence of moisture on it is still visible, it is worth thinking about forced ventilation of the room. Ventilation problems can be solved in the following ways:

    1. Forced ventilation, one of the effective methods, which is suitable even when moisture collects not only on the tank itself, but also on all surfaces of the bathroom. Such a solution to the problem consists in acquiring a special fan, which is installed in the circulation hole.

To supplement air circulation, you can install a grate on interior doors. So moist air will quickly mix with the rest. It is better to entrust installation work to professionals who will correctly calculate the required (specifically for this room) ventilation level. Before starting work, you need to make sure that the ventilation ducts are clean and have good draft.

Often there are situations when the previous tenants of the apartment cover the ventilation hole with some kind of material, and the new guests simply do not pay attention to it.

  1. With a slight manifestation of condensate, you can simply leave the doors to the bathroom ajar, or in their lower part, make a strip of space so that they do not sit tightly in the door frame.
  2. A dehumidifier also helps in the fight against condensate. This electrical device in which the fan is mounted. Thanks to him, moist air flows into the cooling chamber, where the liquid is separated and collected in a container, and the already dried air is returned to the room.

Condensation cannot be removed

It is the owner of the bathroom who will have to decide where exactly to put the comma in this sentence. It all depends on the specific situation and the attitude of all household members to it.

First option. The toilet cistern fogs up a little, but between visits to the bathroom / toilet, everything has time to dry out. Here you can do without radical methods to solve the issue of removing condensate.

Slight fogging of surfaces is unable to lead to irreparable consequences and somehow seriously damage the exterior finish of the room.

Second option. If the drain tank is constantly wet, trickles of condensate now and then flow down to the floor and nothing has time to dry. Here the solution is unequivocal - it is necessary to fix the problem.

Drops flowing down the outer surface of the earthenware container form puddles that need to be wiped off every now and then. Sometimes the situation is quite deplorable - in a day a whole lake is formed in the bathroom. This not only causes inconvenience when visiting the premises, but also greatly unnerves.

Depending on the amount of escaping condensate, prudent owners use methods to eliminate this problem. Some put a towel, while others substitute all kinds of jars and saucers

Constant precipitation of condensate on the drain tank is not only troublesome at the current time, but also threatens with even greater problems in the coming years.

First, drops of condensate can remain in small crevices and in areas that are difficult to reach. Over time, the water will stagnate and begin to smell unpleasant.

Secondly, constant condensation increases the level of humidity in the bathroom. Especially if it's combined. This situation will certainly provoke the growth and active reproduction of mold and fungus.

Mold spoils the appearance of any room. It adversely affects the body of people who constantly use the bathroom, provoking allergic reactions, headaches and other health problems.

Thirdly, the outer surface of the drain tank, being under the constant influence of water drops, will not last long - in the next 2-3 years a network of small cracks will appear, in which mold and fungus will also begin to form.

Fourthly, due to high humidity, all wooden interior items in the toilet room or combined bathroom will begin to rot. Especially if it is a wooden floor, solid oak / beech parquet or other wood species.

Fifth, the metal parts of furniture, water pipes and other items will begin to suffer from corrosion. Even a mirror can suffer - a whole colony of black mold will grow on its inside.

The mold that has settled on the mirror makes it impossible to use it further. You will need to buy a new one, and this is an additional expense item

As a result, the constant appearance of condensate will result not only in the deterioration of the microclimate in the bathroom, but also in the loss of working condition and loss appearance many interior items. After 5-6 years, a major overhaul of a combined bathroom or toilet may be required.

Why does condensation appear on the tank

The condensate that appears on the tank belongs to the category of household problems. To learn how to deal with it effectively, you have to figure out the reasons for its appearance in a particular room.

Only then will it be possible to choose the best option to deal with it.

The nature of the formation of condensate

First of all, you need to understand the nature of the occurrence of "precipitations" on the drain tank. Condensation is water droplets that fall out of the air. They are formed from a sharp temperature drop and act on the surface of objects.

Condensation after taking a shower is a fairly common phenomenon that disappears in a matter of minutes. But the constant trickles flowing down from the toilet bowl and through the cold water pipes can bring a lot of problems.

The condensate on the drain tank is water formed from the impact of cold water at a temperature of 7-15 ° C on the inner walls of a faience container and warm air at a temperature of 25-32 ° C acting from the outside.

From a sharp drop on the outer walls of the container, like dew, drops of water protrude

Causes of condensation on the tank

The appearance of condensate on the drain tank indicates the presence of one of the problems that must be identified and measures taken to eliminate it.

To understand who is to blame, you have to pay attention to the following factors:

  • cold water consumption;
  • ventilation in the bathroom;
  • condition of the tank fittings;
  • humidity level.

With frequent filling of the drain tank, a large amount of condensate forms - cold water does not have time to warm up to room temperature.

Condensation can also be a symptom of a second problem - a non-working ventilation system. Especially if the ventilation hole is removed in the room with the toilet, there is a threshold at the entrance, and the doors fit snugly.

This is quite dangerous for users of combined bathrooms - without proper ventilation, you can simply suffocate.

No matter how beautiful the interior of the combined bathroom is, you have to think about safety first of all by making ventilation holes

Another reason for a drain tank to get wet is a broken shutoff valve. When the seals leak or the float is out of order, the increased water consumption and, as a result, the excessive appearance of condensate on the outer wall of the faience tank cannot be avoided.

Even the most expensive monolithic drain tank is not immune from the breakdown of the internal filling, when you can see puddles of condensate on the floor, which simply should not be there

An increased level of humidity in the bathroom may be due to the circulation of excessively humid air entering this room from other rooms in the house/apartment.

Or due to the fact that the owner of a small apartment constantly dries clothes in the bathroom combined with a toilet. The same problem is observed if wet linen hangs in the kitchen, bordering the bathroom.

Whatever the reason causing the formation of condensate on the drain tank, it must be clearly identified and only then proceed to elimination. After a successful solution of the identified problem, the condensate will also go away.

Faulty ventilation as a cause of condensation

A poorly functioning ventilation system can also cause the cistern to sweat. But many apartment owners, trying to improve the appearance of the room, simply cover the ventilation openings with cladding. This should not be done, it is better to purchase beautiful decorative grilles, specially designed for this.

To check if the ventilation in the bathroom is working well, you must do the following:

  1. Light a lighter or match and bring it to the ventilation hole.
  2. Look at the spark. If it goes out or is drawn into the ventilation duct, then the ventilation system is working properly. When the position of the fire remains the same or the deviation is insignificant, the ventilation does not work.

Be sure to check the ventilation in the bathroom

You can perform ventilation diagnostics by another method - just bring a sheet of paper to the ventilation grille. Its sticking indicates the normal functioning of the system, but if it falls, then measures are necessary to improve the operation of ventilation.

There are two ways to solve this problem:

  1. Cleaning of ventilation ducts.
  2. Forced ventilation system device, i.e. installation of a fan on the exhaust duct. This is the most effective method exhaust air removal.

Tip: To allow fresh air into the toilet, leave a gap of about 2 cm between the bottom of the door and the floor, or install a door valve. It will let air in from the outside and at the same time block the penetration of odors from the bathroom into the apartment.

What are the consequences of this trouble?

In addition to the fact that the toilet bowl is constantly wet and cold due to condensation, this excess moisture can bring a lot of trouble. Dampness leads to deterioration of equipment, which looks unaesthetic due to stains. The fastening bolts are slowly but surely rusting, brown streaks form around them.

Over time, moisture, flowing down from the toilet bowl, collects in puddles, penetrates under the floor covering. From there, it can flow even lower and damage the thermal insulation, or even get to the ceiling of your neighbors from below.

Note! High humidity of surfaces due to condensation leads to the formation of mold, fungus and unpleasant odors in the bathroom

How to prevent it from happening

  • monitor ventilation: clean in a timely manner, check the quality of work with a match or a lighter;
  • often ventilate the room, try not to dry things in the house with the windows closed;
  • monitor the condition of the plumbing: if the drain button sinks, fix the problem;
  • avoid a large jump in temperature: install the toilet further from the heaters;
  • reduce the water supply.

If you plan to repair the entire room, it is advisable to replace the ordinary toilet with the “no tears” option. Then you don’t have to spend money on buying an additional tank, sealant and worry about the flood from your neighbors.

Install a "double" tank

Installing a double tank does not require special knowledge and a lot of time. Specialists identified step by step instructions allowing you to upgrade on your own. Moments:

  1. Just unscrewing a single button and screwing on a two-standard one will not work. You will have to change all the fittings.
  2. The cost of a two-mode drain mechanism will fully pay off with the absence of smudges and water savings. It will be consumed in two modes - "semi-drain" and "standard". Half drain allows you to mix cold water with the one that has already warmed up.

after buying a new mechanism, the water supply is shut off;
the rest of the water is drained from the tank;
old fittings are dismantled;
the entire tank is removed;
installed new system;
then the tank is again installed in its place

Particular attention is paid to the "lambs". With the help of them, you can properly fix the tank, because even a minimal deviation can cause noise or leakage.

At the end, a double button is twisted and a valve for water supply opens. The whole procedure will take only 20-30 minutes.

Check ventilation regularly

Faced with the problem of ventilation, experts recommend paying attention to the entire microclimate in the rooms and non-residential premises. As an alternative to automatic system, which intersects with light, can be distinguished:

  1. Installation of holes in doorways. To make them look natural, you can insert a grill or special caps with a filter mesh into them, which will eliminate the transfer of dust and small particles due to the formation of air flow.
  2. There are special air dryers that are installed in the ventilation hole.
  3. Salt can be a budget option. By placing a small amount of scented bath salt in all rooms, you can partially get rid of excess moisture.

The reason for the accumulation of condensate can be hidden not only in a plumbing malfunction. Often the problem is initiated by neighbors who regularly heat other citizens. For example, setting stretch ceiling, you may encounter the fact that the neighbor will simply hide the fact that there was a leak. Unpleasant smell of mustiness and dampness without apparent reason may be the first call to check the walls.

The second popular problem is the violation of the tightness of the pipes. Even the PFC system, which ranks highly in products related to plumbing engineering, has its own lifespan.

The third reason may lie in the eyeliner itself, which quickly fails due to impurities in the water.

Any repair should begin with an analysis of the situation. Putting a rag under the tank or regularly removing drops from the surface of the tile is not an option. Neglect can lead to poor health and unnecessary costs for finishing the entire room.

Reasons for the appearance

Moisture drops appear on any surfaces that are affected by sudden changes in temperature. The same situation is observed with the toilet bowl. A temperature difference of 15°C is sufficient for fogging to occur.

Drops occur for the following reasons:

  • high humidity in the room,
  • hot pipes (working heating system in the bathroom),
  • lack of a ventilation system or blockage of the opening with unnecessary objects,
  • breakage of shut-off valves in the drain tank (water flows out in a thin stream from the tank, new liquid from the water supply comes in its place),
  • frequent use of plumbing (the liquid in the tank does not have time to warm up to the required temperature parameters).

After determining the causes of fogging, you can begin to get rid of the condensate on the toilet cistern with your own hands.

Causes of condensation on the surface of the tank

First you need to understand what the concept of "condensate" means. If you delve into physics, the “sweating” of devices causes a sharp change in temperature. This phenomenon is often observed after taking a shower, when the mirror “sweats”. With high-quality ventilation and the absence of problems, water evaporates quickly.

If moisture begins to collect on the walls of the tank and drip down, this may be the “first call” indicating a system malfunction. Experts identify the following reasons:

  1. Frequent use. The water accumulated in the tank does not have time to warm up to room temperature. Often this problem can be found in large families.
  2. Drain breakage. Due to the constant leakage, the water in the tank is filled with cold water, which complicates heating.
  3. Increased indoor humidity. Many people dry things at home, which causes the effect of a greenhouse.
  4. Next to the tank is a heating device. As an example, we can highlight the presence of a dryer, passing pipes with hot water.

These are the main issues that need to be addressed first. As practice has shown, many of them can be solved on their own.

Negative consequences

The owner of an apartment or a private house has the right to independently decide when to start solving the problem with condensate. In most cases, the tank does not sweat constantly, water drops have time to dry. This does not create problems or negative consequences, but if the tank is constantly sweating, then drops of water will flow down the surface of the device and fall to the floor. Small puddles will appear, which will have to be constantly cleaned, which creates certain inconveniences even for the owner of the dacha.

The main consequences of moisture condensation on the tank:

  • drops of liquid fall into the cracks of the floor covering. It is virtually impossible to remove water from there. After some time, mold forms on problem areas, a specific smell appears,
  • the humidity of the air in the room increases, which leads to the intensive development of pathogenic bacteria, the appearance of fungus and mold on the walls of the room and plumbing surfaces,
  • if the toilet bowl sweats for several years, then the material of the device will begin to break down, cracks will appear on it, in which microorganisms harmful to humans will develop,
  • high humidity in the bathroom or toilet leads to rotting of wooden structures,
  • metal pipes and furniture made of steel will begin to rust, mold will appear on the inside of the mirrors.

Why does condensation form?

Condensate on drain tank the toilet bowl appears as a result of the condensation of water vapor, which is present in the air. It condenses on surfaces that are colder than the dew point. This is because the air, when cooled, can no longer hold the previous amount of water vapor in the gaseous state and it condenses. In addition to temperature, the relative humidity of the air has a direct influence on the condensation process. As humidity increases, the risk of condensation increases. Unfortunately, determining the value of humidity is difficult to predict at the design stage of a bathroom ventilation system.

In construction and renovation, we widely use insulation to reduce energy losses caused by changes in the temperature of the transported medium when the ambient temperature differs from the temperature inside the system. In the case of devices with average temperatures below ambient, such as a cistern in a toilet, the insulation has another very important function - it prevents condensation from forming on the surface of the device.

Why is the toilet cistern sweating?

Condensation on the toilet tank appears due to the fact that the temperature of the water in it differs from the air temperature in the room by an average of 15 degrees. That is why the surface begins to "sweat". Water enters the toilet from a pipeline that is located on the street or underground, if it is winter in the yard, and the room is heated at the same time, then the difference will be huge.

Condensation may occur due to the following factors:

  • water leakage - appears due to a malfunction of parts of the fittings when the tank begins to fill with cold water. In this case, condensate forms regardless of the pressure of the water, but it depends on how much the tank fogs up. To get rid of the condensate formed due to leakage, you need to adjust the drain system or change the faulty parts of the toilet;
  • excessive water consumption - the more often the toilet is flushed, the more cold liquid enters it. Accordingly, the likelihood that the surface will fog up will be higher. To solve this problem without compromising the cleanliness of the toilet bowl, you need to adjust it so that less water is supplied. If the family is large and you have to use the toilet often, it is better to purchase a toilet with a stepped or adjustable drain. This will significantly reduce the use of liquid and can save the tank from the appearance of condensates;
  • too cold water - if you live in a private house, you can additionally insulate the water supply route, this will slightly heat the water when it is supplied and reduce the likelihood of condensation on the toilet bowl;
  • high humidity in the bathroom or bathroom - to cope with the fogging of the tank with high humidity in the toilet, install air dryers;
  • problems with the ventilation system - if they exist, then the air masses will not be able to exit qualitatively, respectively, this will lead to condensation. For example, the quality of ventilation deteriorates significantly if the holes are tightly lined, so we do not recommend doing this in places of high humidity.

How to prevent condensation

It is possible to prevent this problem, but it is impossible to say with full confidence that in the future condensate will not appear on the tank. So, you can prevent the accumulation of excess moisture on the drain device by taking the following measures:

  • install high-quality ventilation;
  • regularly ventilate the premises;
  • purchase a half-flush tank, in which, after draining warm water, some of it remains, which helps prevent condensation;
  • once a quarter or every six months, check the ventilation;
  • in time to eliminate the malfunction of the parts of the drain tank.

If these measures remain ineffective, then it makes sense to change the old plumbing to a modern toilet model, where the tank is equipped with an additional anti-condensation shell.

Why does condensation appear on the toilet bowl

It is harmful to health when the air in the apartment is dry, but high humidity also leads to not very good consequences. This can also cause the tank to sweat. Often this occurs where clothes are dried indoors, there is a large aquarium or lovers of indoor flowers, trying to create conditions close to natural for their green pets, they are constantly sprayed.

The most common cause of condensation is high humidity in the apartment.

These reasons are easy to eliminate - you can put air dryers or take out the laundry after washing on the balcony. It is more difficult when there are leaks in the plumbing or heating systems, ventilation does not work well. The most common cause is the continuous flow of low temperature water due to problems in the design of the drain device or due to frequent descents. Condensation in these cases is the result of the contact of warm room air with the constantly cooling surface of the cistern.

What is condensate

In the general case, condensate is a water sediment that arises from the air and settles on various surfaces. As a rule, it appears due to a sharp change in temperature.

Often a similar phenomenon can be observed after taking a shower on the walls of the booth and other objects, however, such moisture evaporates within a few minutes. But if thin streams of water constantly form on the toilet bowl or pipes, this is a problem and certain measures must be taken to eliminate it.

Do I need to remove it What consequences threaten a new appearance

Any moisture must be dealt with. When it comes to condensate on the tank, experts identify the following consequences:

  • the accumulation of sediment in small cracks can lead to chips on the enamel of the toilet bowl;
  • due to the constant stagnation of water, mold occurs, which negatively affects respiratory system household members;
  • unwanted bacteria appear;
  • corrosion begins to destroy metal elements.

If you do not immediately begin to deal with excess moisture, then in a few years you will have to make a major restoration of the entire bathroom. For the average citizen, such expenses can negatively affect well-being.
