Why does the toilet sweat. Condensation on the toilet bowl: how to get rid of, the causes of fogging. Reducing the volume of drain

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 may be due to a large amount indoor plants, drying a large number wet laundry, leaks in 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 the level room temperature.

To understand why the toilet cistern is sweating, you need to remember a little the school physics course. 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.

To isolate the walls of the tank from the effects of cold water, some amateur craftsmen try using thermal insulation materials, which are glued to them from the inside of the container. However, this technology does not completely solve the problem of condensate.

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.

Often the owner of the apartment has a question about what to do if the toilet bowl is sweating.

At first glance, it may seem that the question is completely trifling and its solution is not worth a damn.

However, long-term practice shows that this problem is much more complicated than it seems.

As a result of high humidity in the room, a favorable environment is formed for the formation of mold and fungus.

The toilet cistern is such a device that is activated many times a day. And if timely action is not taken, big troubles can follow.

Causes of condensation

Before taking on the elimination of this trouble, it is necessary to find out why condensation forms on the toilet bowl and on adjacent pipes. There is no secret here.

The drain tank sweats for two reasons:

• high air humidity;
• low temperature of the water entering the tank.

According to the elementary laws of physics, when warm, vapor-saturated air comes into contact with a very cold surface, water droplets form on this surface - the tank “sweats”.

Over time, puddles accumulate from the drops, which again saturate the air in the bathroom with moisture. In fact, a miniature water cycle is formed in a limited space.

It is unpleasant to live in such an atmosphere. However, before doing anything, you need to conduct a survey of the premises.

If the water pipes have been serving for more than a decade, then you need to carefully examine them for leaks.

The next step is to check the serviceability of the valves in the toilet bowl.

Then you should pay attention to the quality of ventilation in the bathroom. If stagnation is observed here, then natural or forced air flows should be formed.

The influx of fresh air and the exhaust of stagnant air will help reduce its humidity.

How to eliminate fogging?

To stop the cistern from sweating, you can limit the flow of water each time you use the toilet. In this case, the quality of the flush should not decrease.

Today, in the plumbing market, you can purchase a drain tank with two buttons.

Such a flow rate control system allows you to use the entire volume of water from the tank or only part of it. However, a simple change of the toilet may not bring the expected effect.

And before making a replacement, you need to make sure that the decision is correct. The simplest steps should be taken to help determine the true reason why the toilet bowl is sweating.

Ventilation cleaning

In the houses of the old building, natural supply and exhaust ventilation was provided.

The level of development of building technologies did not allow the use of more efficient methods, such as forced ventilation.

In order for the natural ventilation mechanism to operate effectively, it is necessary to ensure the flow of air into the room from the outside.

Air from the street entered through the cracks in the door and window openings. And if these air intakes disappear for some reason, then this natural movement stops.

Often this happens when plastic windows are installed in the apartment.

Years of experience have shown that the mechanism natural ventilation works well in winter. And the drain tank in this case either does not sweat at all, or sweats very slightly.

In summer, in hot weather, the hood does not work very well. If you clean the ventilation duct, the air movement resumes, but only slightly.

Doing such procedures is constantly difficult and does not make sense, since the result will always be minimal.

The most effective solution would be to install a supply and exhaust fan in the toilet. It is necessary that it automatically turn on when you press the button on the toilet cistern.

Repair of defective fittings

If the shut-off valves in the toilet bowl are faulty, then water flows through the toilet and flows. In this case, the process of condensate formation occurs constantly.

In order to stop it once and for all, you must perform overhaul drainage mechanism. Practice shows that it is not rational to replace individual parts of this device.

In stores, as a rule, a kit is sold that includes a float valve, the float itself, a "pear" and traction. From these products, a drainage device is assembled and installed in the tank.

When you can’t do it yourself, you need to invite a plumber.

Many residents in this case prefer to purchase a new toilet already assembled and install it in place of the old one. Experts recommend doing just that, if financial condition allows.

Today, new models of toilet bowls are presented on the market. The updated toilet bowl has double walls, and its outer side does not sweat under any circumstances.

A plastic container is installed inside such a tank. An air gap is formed between it and the outer wall, which serves as a heat insulator.

Some craftsmen are able to make such a device with their own hands. But for this you need to have the skills to work with such devices.

General rules

The bathroom is considered the most important room in the apartment. high-rise building. This is where all the residents come several times a day. And it is necessary to keep this room clean and tidy.

First of all, ventilate it. You need to do this regularly. It is necessary to monitor the serviceability of all taps and the drain tank.

If condensation occurs, the cause of this phenomenon should be determined and eliminated as soon as possible. No surface should sweat.

If you can’t do it yourself, then you need to call a qualified specialist.

Dampness, and as a result, a specific smell, mold, dissatisfaction with households, and sometimes neighbors from below due to stains on the ceiling - these are the unpleasant consequences of constant condensation on the toilet bowl. The question becomes how to get rid of this phenomenon.

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, constantly spray them.

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 is poor. 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 a constantly cooling surface of the drain tank.

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.

Attention: when purchasing a new membrane, check that both the material and dimensions are fully consistent with the old sample, otherwise the leakage will remain.

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 more easily if the leak occurs due to the incorrect position of the float, in order to eliminate it, it is enough to open the tank and return the lever to its normal position.

Faulty ventilation as a cause of condensation

A poorly functioning one can also cause the tank 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 it works well, you need to 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. 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.

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:

• 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.

Tip: neoprene, expanded polystyrene and other materials can be used to insulate the tank.

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.

A modern person makes certain demands on the toilet, it should be comfortable, beautiful and, of course, clean. And suddenly a problem arises when, it seems, all measures have been taken to create a convenient and aesthetic closet: the system for supplying and discharging water and wastewater has been replaced, and a new toilet bowl has been installed, but moisture collects on it. And not just on the pipes, but on the tank, which, in theory, should serve without any interference.

What can we expect

Condensation on the toilet bowl - this is initially a minor nuisance that can result in a number of non-critical, but rather troublesome consequences, such as:

• Accumulation of puddles of water on the toilet pedestal and then on the floor.
• The appearance of dampness, and then, as a result, mold, fungus and unpleasant odors.
• Rusting of the metal elements of the plumbing fixture, for example, the details of attaching the toilet bowl to the floor.

You, of course, can endlessly wipe the condensate and substitute containers for collecting drops, but who needs this hectic economy, it’s easier to get rid of this “ailment” once and for all.

In this article, we will try to understand why the toilet cistern is sweating and tell you what to do if there is condensation on the toilet.

Causes of condensation

If such a situation arose in the house, it is better to immediately figure out why the toilet bowl is sweating and eliminate it. The main factors in the appearance of "tears" on it are:

1. Increased humidity in the apartment, including in the bathroom, due to:

• Inefficient work.
• The presence of leaks in life support systems (water supply, heating).
• A large number of indoor plants that require regular watering and irrigation.
• Frequent drying of laundry in large volumes, for example, at the birth of a baby, etc.

1. Shutoff valve failure, leading to a continuous supply of cold water to the tank, which does not have time to warm up to room temperature. In this case, if the temperature difference between the water in the tank and the ambient air is 10-15 degrees, condensation will certainly occur on the surface of the drain tank.
2. The location of hot water pipelines in close proximity to the drain tank.

Now, knowing why the toilet is sweating, you can decide on methods for eliminating the problem.

Ways to deal with the resulting condensate

Let's touch on each reason separately and figure out what to do if the toilet bowl sweats in a particular situation.

Drain system malfunction

The first thing you should pay attention to is the correct functioning of the tank itself. With a quality installation of a plumbing fixture, there should not be a continuous flow of water from the tank into the toilet.

It's easy to spot:

• Visually. Constantly flowing water leaves characteristic traces on the toilet bowl.

• Aurally. The continuous filling of the drain tank is accompanied by noise, which in itself can already become an unpleasant irritant for the inhabitants of the home.

Attention! In addition to the troubles described above, a permanent leak of water into the toilet will also adversely affect the finances of the family if a water meter is installed in the house.

Any man can cope with the repair of the drain device with his own hands, it is enough to have a set of wrenches, fum-tape or sanitary sealant with you.

Insufficient ventilation

If no malfunctions are found during the examination of the toilet, pay attention to the ventilation in the bathroom.

Checking the draft in the ventilation duct is very simple, you need to bring a piece of paper to the grate at the entrance to the ventilation shaft. When functioning properly ventilation system the sheet will be attracted to the grate and will be held without assistance.

Otherwise, measures should be taken to troubleshoot and improve ventilation efficiency.

How to do it?

• First, you need to continue the examination of the ventilation duct and, if a blockage is found, clean it yourself, or call the workers of the relevant services.
• Secondly, to ensure free air exchange in the room by installing it in the lower part of the door. You can also solve the problem due to a sufficient gap between the door to the toilet and the floor.
• If all measures have been taken, and condensate still appears, you will have to arrange forced ventilation in the bathroom by installing a household fan in the ventilation duct.

Advice! It is better to entrust the selection of a device model of the appropriate power to specialists.

But mounting the fan is a very simple task, besides detailed instructions to the unit will help to complete it in a short time, and the price of the issue will be no more than a few thousand rubles.

Note! Especially relevant is the forced ventilation device in combined bathrooms, where, after taking water procedures humidity levels inevitably rise.

It is very convenient when the fan turns on and off synchronously with the lighting in the bathroom. If necessary, you can connect a relay that allows you to prolong the operation of the fan for some more time after the light is turned off.

Lowering the temperature in the bathroom

Establishing a favorable temperature in the bathroom can also help in the fight against condensation.

To do this, it is desirable to take out of the room:

• Hot water pipelines.
• Heated towel rails powered by the heating system.

The greatest effect can be achieved by performing all the above measures to eliminate condensate on the toilet flush tank in the complex.

Additional measures

When choosing plumbing for your home, pay attention to the new improved models of toilet bowls with double cistern. This refers to an additional plastic water tank that does not come into contact with the outer ceramic one. This eliminates the possibility of condensation on the surface of the drain tank.

Here's practically everything about how to get rid of condensation on the toilet.

Conclusion

Now it remains for you, following the above tips, to carry out the necessary work and we guarantee you that in the near future you will forget about the “tears” on the plumbing fixture. If this problem arose with new equipment, then it is better to contact the store and return it under warranty, let the manufacturers deal with the condensate.

In the presented video in this article you will find additional information on this topic.

Modern toilets are comfortable and aesthetically pleasing, and inside they smell pleasantly scented products. To be comfortable in the bathroom, it requires special care. Do you agree?

The room must be constantly cleaned and promptly eliminate problems, including the formation of condensate. If water constantly flows down the outer surface of the tank, an unpleasant smell appears in the apartment over time, and the plumbing fixture loses its attractive appearance. appearance. 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. Of course, you can adapt some container to collect water, and then do not forget to empty it of the contents in time.

To get rid of the condensate on the toilet bowl and avoid negative consequences, you need to find out why the tank in the bathroom is sweating.

The most common causes of condensation on the tank are:

temperature difference

As a rule, the air temperature in the bathroom is higher than the surface temperature of the tank, since the latter is constantly filled with cold water. In the bathroom, additional heat sources are often installed, for example, heated towel rails and underfloor heating, which makes the temperature difference even greater. This is especially true during the cold season.

Condensation forms on the tank of sanitary equipment due to the fact that the air temperature in the room differs from the temperature of the water in the toilet bowl by about 15 degrees.

Therefore, the outer surface of the tank begins to fog up.

Malfunction in the drain mechanism

Often, condensate appears when the drain tank is constantly leaking, which, as you know, most often occurs when the float valve breaks down. If this is the case, then the problem is easily solved by purchasing a new valve.

Due to a faulty mechanism, cold water from sewer pipes flows in the tank continuously, not having time to settle.

As a result of the movement of cold water flows, condensate appears. If there is a meter, the landlord will have to pay for the leak.

Most modern plumbing models do not involve "local" repairs, so manufacturers do not produce small spare parts for them.

In the event of a breakdown, you will have to purchase a set of shutoff valves. If you can identify faulty structural elements and make repairs at the site of the breakdown, you will be able to reduce the excessive consumption of cold water, which is important for housing with a meter.

You can solve the problem without plumbing skills with the help of a master.

If you are familiar with the principle of operation of the drain system, then the repair can be done independently, while saving on calling specialists.

Depending on the model of the toilet bowl, there are two ways to solve the problem - replacement of valves or local repair of failed structural parts.

Condensation is formed at any pressure of water, but the degree of fogging of the tank depends on the power of the pressure. To fix the problem, it is necessary or to change the faulty parts.

Lack of ventilation

A well-functioning ventilation system is the main condition for maintaining the optimal level of humidity in the room. If the bathroom is poorly ventilated, numerous problems appear, including condensation on the drain tank. Checking the condition of the ventilation openings 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.

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.

If your toilet cistern is sweating, you need to urgently check the ventilation system in the bathroom.

Bring paper, a candle or a lighter to the ventilation grille. The system works great if the paper sticks and the flame burns evenly. If paper falls or the flame goes out, then urgent measures must be taken to restore ventilation.

You can solve the problem of the constant appearance of condensate in the following ways:

• Cleaning of ventilation ducts.
• Installation of an additional fan on the exhaust duct.
• An effective option for getting rid of exhaust air and obtaining clean air is to leave a gap 2 cm high.

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.

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.

Buying a dehumidifier

Another solution to the actual problem of high humidity in the bathroom is the purchase of a dehumidifier.

The principle of operation of the electrical appliance: a powerful fan directs the flow humid air into a special cooling chamber, in which the process of moisture condensation and its separation into a special container takes place. Then the dried air is heated and successfully returned to the bathroom.
