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

Toilet 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 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.

Insufficient toilet ventilation

Sometimes it is enough to install a ventilation device or an additional fresh air supply device to say goodbye to the problem forever.

How to check the ventilation system?

If your toilet cistern is sweating, you need to urgently check the integrity and serviceability of 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.

The process of diagnosing the operation of ventilation can be carried out independently by the owner of the apartment in a simple but effective way with the help of improvised means.

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.

An excellent solution is to install a multifunctional door valve that lets air in from the outside and at the same time blocks unpleasant odors, preventing them from spreading throughout the living quarters.

In any room with high humidity (toilet, kitchen, bathroom) there are ventilation windows that provide optimal air circulation in the room

A malfunctioning ventilation system can be the cause of the cistern sweating. But most owners of living space, trying to make the room look better, simply close the ventilation holes with trim. You don’t need to do this, it’s a good option to buy beautiful decorative grilles, which are intended for this.

Installing a fan in the bathroom

In order to stop the process of fogging of the tank, walls and floor in the bathroom, try installing forced ventilation in the room.

Sometimes a simple fan, which is mounted in the vent and activated when the light in the toilet is turned on, can eliminate the formation of condensation on surfaces. If this does not solve the problem, it is worth calling specialists to install more efficient ventilation systems.

You can improve the quality and circulation of air flows in the bathroom by installing additional modules in the room - fans and hoods

If the toilet cistern is sweating in the toilet, you should first check the operation of the ventilation. Some owners, in order to "cultivate" the bathroom, completely seal the existing ventilation holes.

Consumers should pay attention to the decorative grille, which will save you from problems with ventilation and will look aesthetically pleasing. One way to resolve the issue is to leave the door to the bathroom ajar.

The most effective way to combat condensation is to install a professional ventilation system that maintains an optimal level of humidity in the room.

Installation of forced ventilation is often used in combined bathrooms, which are characterized by the appearance of condensates on the toilet, tiles, ceilings, mirrors and other surfaces. In this case, it is better to install a professional ventilation system.

The power of the equipment must correspond to the operating conditions, then condensate droplets will no longer appear.

Installing an axial fan in the exhaust hole located in the bathroom is carried out in the following order:

In order to verify whether the ventilation in the plumbing unit works perfectly, you need to re-verify: light a lighter (candle, match), bring it to the hole and look at the light.

If it goes out or is drawn into the ventilation duct, the ventilation system is functioning well. If the position of the flame remains the same or the deviation is small, another method must be considered.

Reasons for sweating

To get rid of the problem, you need to find the cause that causes it.It is known that dew appears when the air is much warmer than the object on which it falls. However, when it appears on objects, it causes corrosion and provokes the growth of mold, which leads to the destruction of the material. Even at room temperature and normal humidity in the bathroom, the water in the drain tank, cooled to 5-6 degrees, will cause sweating. In this case, the material from which the drain container is made does not matter. What causes temperature differences and high humidity, which lead to the appearance of water droplets on the drain tank?

• The exhaust system does not work well or does not work at all. To check, you need to bring a burning match to the exhaust pipe and look at the movement of the flame whether there is thrust or not. In the absence of draft, it is necessary to contact the managing organization to inspect the entire ventilation system of the apartment passing by.
• If hot water pipes pass through the bathroom, they will also cause temperature changes. To eliminate the cause, it is necessary to isolate them with special covers for pipes, which are provided with cuts for ease of installation.
• High humidity in the room can be caused by fumes from the bathroom entering the toilet. To eliminate them, it is necessary to separate the exhaust systems of the bathroom and bath and organize forced ventilation.
• The reason for the appearance of condensate on the walls of the toilet bowl can be a slight breakdown of the drain mechanism. Because of it, a thin stream of water flows through the drain hole all the time, which means that new cold water constantly enters the tank, which simply does not have time to heat up. Too cold walls of the tank in a warm room inevitably fog up.

What threatens the accumulation of condensate

High-quality plumbing has virtually no parts that can be subject to the destructive power of corrosion. Fasteners used to assemble equipment are made of stainless metals or wear-resistant plastics. However, not all plumbing manufacturers use high-quality materials. Moisture drops formed on the walls of the drain tank increase the level of saturation of the air with water vapor, which can lead to corrosion on the metal parts with which the tank is fixed.

Constantly collecting droplets will lead to corrosion on metal elements.

In order to avoid the appearance of rust, it is desirable to cover the fasteners with a layer of anti-corrosion grease.

If the design of the toilet bowl provides for a hinged tank, and not installed on a shelf, then drops of condensate will leave not only unsightly smudges on the walls, but also create favorable soil for the appearance of mold or fungus.

Drops of perspiration can drip onto the floor, forming a puddle that will become a hotbed of bad smell. In addition, the water, evaporating from there, will serve as a source of increased humidity, which again will lead to the appearance of fungal infections. Water flowing from the walls of the drain tank will inevitably come into contact with the pipes, which will cause them to corrode. Rust will appear on all unprotected steel parts of the structure, even on the tank itself if it is made of metal.

Temperature rise

If the cause of condensation is cold water that does not have time to warm up to room temperature, then this problem can be solved.

Condensate on the toilet bowl - how to get rid of:

1. Install a water heater. The device is placed inside the tank. The water heater will heat the water to such a temperature that condensate will not appear.
2. Insulate sewer pipes. It is desirable to do this at the time of their installation and in this form be placed under the ground. So the water entering the tank will no longer be so cold.
3. Overlap. First you need to remove everything that will interfere with the work. Then cut the pipes in half. Thus, it will be possible to regulate temperature differences.

In such simple ways, you can get rid of water droplets. Methods are fast and cheapest.

How to prevent its occurrence?

There are several relevant recommendations to eliminate the appearance of unwanted drops. For example:

• 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 make repairs to 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. Experts have identified step-by-step instructions that allow 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.

Stages:

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;
a new system is installed;
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 rooms and non-residential premises. As an alternative to an automatic system that intersects with light, we can highlight:

1. Installation of holes in doorways. To make them look natural, you can insert a grid 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, when installing stretch ceilings, you may encounter the fact that the neighbor will simply hide the fact that there was a leak. An unpleasant smell of mustiness and dampness for no apparent reason can be the first call for checking 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.

Keep or take away - that is the question

Option number 1. The toilet cistern began to fog up a little, but everything has time to dry in between visits toilet and bathroom. Here you can do without drastic measures. A slight fogging of the surface cannot lead to irreparable consequences and seriously damage the exterior finish.

Option number 2. If the drain tank is constantly wet, and trickles of water constantly flow down to the floor and nothing dries up on its own, then the solution is unequivocal - the problem should be fixed. Droplets that flow down the outer surface of the container create puddles that have to be constantly wiped up. Sometimes the situation is completely deplorable - a huge lake turns out in a toilet in a day. This is not only inconvenient, but also unnerving.

1. Droplets of condensation are ways to stay in small crevices and hard-to-reach areas.Over time, the water begins to stagnate and smell unpleasant.
2. The constant appearance of condensate increases the level of humidity, and especially if the bathroom is combined. This situation can provoke the growth and reproduction of fungus and mold. Mold will ruin the look of any room. It also negatively affects the human body, provokes allergies, headaches and other health problems.
3. The outer surface of the tank, being under the round-the-clock influence of water drops, can not last long - in the next few years, a network of small cracks appears, in which mold and fungus appear.
4. Due to the high level of humidity, all wood interior items in the room begin to rot. Especially if it is a table, solid oak / beech or other wood parquet.
5. Metal parts of furniture, plumbing pipes and other items will begin to suffer from corrosion. Even a mirror can be damaged - a huge colony of black mold will begin to grow on its inside.

And the mold that appeared on the mirror will no longer make it possible to use it in the future. You will need to buy a new one, and this is an additional cost. As a result, constant condensate will result not only in the fact that the microclimate will become worse, but also the working condition and appearance of almost all interior items will be lost. At this rate, after 4 years, you can do a major overhaul.

What can we expect

Condensation on the toilet - 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.

Many owners completely insulate pipes to avoid temperature differences and, as a result, condensation.

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.

How to get rid of condensation on the toilet bowl with your own hands

To solve the problem with condensate in the bathroom, you must correctly identify and then eliminate the cause. In most cases, you can deal with the trouble yourself with the help of improvised means and simple manipulations. However, sometimes the help of specialists or the replacement of plumbing is required.

Why is it important to identify the cause and eliminate it as soon as possible? The answer is simple - a neglected problem quickly manages to cause many serious consequences:

1. The appearance of rust on the pipes and the gradual destruction of the water supply.
2. An increase in air humidity, which contributes to the development of mold and an unpleasant odor.
3. Rotting materials from which floors and ceilings are made. This phenomenon leads to the destruction of floors between apartments and very expensive repairs.

Condensation in the bathroom or toilet leads to the appearance of fungus. It not only spoils the aesthetic appearance of the room, but also poses a health hazard to residents of an apartment or house.

Forced ventilation and normalization of humidity

If the problem of condensation is due to high humidity in the room, take care to create additional forced ventilation. The fan pulls out moist air, and it is replaced by dry air from the living quarters.

For the normal operation of the ventilation system follow a few simple steps:

1. At the bottom of the interior door, install a small grill to ensure normal air circulation in the room.
2. Clean the ventilation well and opening from construction and other debris.
3. Install a mains powered fan in the system.

When installing the appliance, select how it will be turned on. The best option is a direct connection to the switch. In this case, it will start when the light is turned on.

With an isolated connection, the fan is switched on as required by a separate switch.

The first step in eliminating condensation is setting up the ventilation system. Clean out the well and make sure there is sufficient draft to remove damp air from the room

Normalize air humidity in bathroom in a private house a special device - a dehumidifier will help. The principle of its operation is quite simple - a powerful fan transfers air into a special chamber, where it condenses under the influence of low temperatures, and moisture is collected in a special container. Then the dried air is heated and returned back to the bathroom.

Normalization of water temperature in the tank

If the temperature difference is the cause of the problem, protect the tank from contact with cold water. Use insulating materials for insulation: tepofol, foam or polyethylene foam.

Work order:

1. Empty the tank and dry it well.
2. Glue the thermal insulation material with waterproof adhesive and press firmly to the surface.
3. Sealant fill all the cracks and go through the joints.
4. Wait for the glue to fully set and open the tap for water supply.

To get rid of perspiration on plumbing will help increase the temperature of the liquid in the tank. This can be achieved by connecting a warm water faucet or boiler to the toilet system.

Another way to deal with condensation is to increase the temperature of the water entering the tank. To this end, insulate and insulate all pipes. If such a trick does not help, you will have to install a boiler that will heat the water to room temperature and supply it to the toilet system.

An easier and more affordable way is to install a half-drain mechanism. Thanks to this, half of the warm liquid will always remain in the tank, which will dilute the ice water coming from the water supply.

Installing a half-drain mechanism will help to avoid condensation and save the family budget.

Toilet replacement

If none of the methods used has brought the desired result, it's time to update the plumbing. When buying a toilet, give preference to products equipped with an anti-condensation shell.

Such toilets have a unique design: outside it is a classic tank, and inside - a plastic vessel for water. The presence of an air gap between ceramics and plastic provides protection against condensation.

With the ineffectiveness of simple ways to deal with perspiration, a radical method remains - replacing plumbing. Choose a toilet in which the tank has a double system and an air gap

To install a new toilet, ask a plumber for help.Even the slightest mistake can lead to an accident and flooding, as well as to financial expenses that are many times higher than the cost of the services of the master.

Forced ventilation

It is this reason that is most often found when dew appears in the bathroom.

In the bathroom and toilets, this is due to their characteristics. Most often, it is these rooms that suffer from insufficient ventilation.

To check how well the air is getting out of the toilet room, simply hold a piece of paper in the exhaust vent. The check is carried out with the door open, then with the door closed.

It can also be carried out with a lighter, bringing the fire close to the ventilation duct.

If the thrust is good, you will again need to check the tank itself and the entire structure, and look further for the cause. You probably missed something in your rush.

If there is no traction, then you need to make it compulsory.

There are several ways to make moisture disappear:

1. A simple method is to install fans instead of a regular grid. They are mounted in the circulation hole. You just need to remove the grid that was previously there, and put the fan. Usually they are round, connected to electricity. Do not connect to light switches. Sometimes it is required that the fan work for a day (for example, when drying large things in the bathroom), and if the light is also on, imagine how much electricity is wasted. The fan rotates quickly and brings fresh air into the room.
2. A difficult method is to assemble a new ventilation system. To do this, you will need to purchase pipes, assemble them, place them where necessary, having previously made calculations (how much material is needed and where the structure will pass).Forced ventilation should be closed with a false ceiling so that the general appearance of the room does not deteriorate. It is advisable to install fans that are powered by electricity and spin when you need, and not when the light turns on or off.

To combat condensate, all means are good. Therefore, even for another reason, it is recommended to install forced ventilation.

Condensation is bad wherever it appears. It causes a lot of problems, so deal with it as soon as possible, otherwise later you will have to change the pipes, the tank and look for how to remove the mold.

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;

• 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.

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 is the key to protection against high humidity and mold

Many users prefer to leave the bathroom door open, 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.

How to eliminate fogging?

In the main, the elimination of either high humidity in the room, or the elimination of temperature differences can help. You can remove condensate from the toilet bowl by one or more of the following actions.

Setting the drain mechanism

For starters, you can try to repair / adjust the drain system. The accumulation of water on the walls of the tank can be caused precisely by a malfunction of this unit. If the drain valve is not firmly seated, water can constantly go into the toilet.The tank in this case will be continuously filled and cooled. In such a situation, the volume of condensing liquid can reach 1-2 liters per day.

The fight against perspiration will be more effective if you start by repairing drain and shutoff valves. You should check the performance of all nodes and, if necessary, replace with a new one. To quickly deal with the repair, we advise you to see how the toilet is arranged.

Before installing a new mechanism, you need to check for lime deposits on the drain hole. If necessary, remove them and replace the rubber seals. To avoid deformation of the sealing gaskets, it is recommended to tighten the nuts not with keys, but with your hands, but with the maximum possible force.

Reducing the volume of drained water

You can try to overcome the condensate on the drain tank by reducing the volume of the drain. Of course, with a large number of residents and continuous use of the bathroom, this will be difficult to achieve. However, the amount of drained water should be kept as low as possible. To do this, you can use the half-descent button. In the absence of such a system, it is recommended to replace the outdated device with a modern one. It will help to get rid of condensate and save a certain amount of water.

Elimination of temperature difference

Condensate formations can be combated by heating the accumulating water. If the supplied water is the same temperature as the air in the room, then drops will not accumulate on the surface of the tank. This can be done by connecting a system with instantaneous water heating, which has a thermostat, and creating proper thermal insulation of pipelines. The temperature can be set between 20-25°C.

On the other hand, you can lower the air temperature in the bathroom. But not everyone will like this plan of action.

Air dryer installation

The device must be selected in accordance with the level of humidity, area of ​​\u200b\u200bthe room and your budget. Based on the principle of action, 2 types can be distinguished:

1. Absorption - a container filled with an absorbent substance that perfectly absorbs moisture. Silica gel is often used.
2. Condensation - cools the air, and excess moisture condenses and settles inside the device.

Creation of high-quality ventilation

Protecting the tank from condensation must begin with good ventilation. Not infrequently, during repairs in a private house / apartment, the ventilation openings are closed or they simply do not undergo maintenance. However, this is a significant error, since it is she who is able to completely eliminate problems with fogging of the toilet bowl.

Checking the operation of ventilation can be carried out very simply: just bring a sheet of paper to the hole or bring a lit match and put it out. If sufficient draft is observed, the hood is functioning normally. If there is no traction at all or it is weak, then you should cleaning of ventilation ducts.

One of the easiest ways to solve the problem is to install forced ventilation.

Installation of a special tank

Modern technologies have long begun to solve the problem under consideration. One of them is a toilet with a double tank. The modification looks like this - a plastic tank inside, and outside - a familiar ceramic casing. A gap is created between the ceramic and plastic containers, which ensures that the water temperature is maintained at the same values ​​as room temperature.Installation of such a system can unequivocally solve all issues with the deposition of condensate.

However, such double tanks have one significant drawback - a high price.

Internal thermal insulation

Buying an expensive cistern / toilet bowl is not always advisable. You can solve the problem yourself. For this, polyethylene foam is placed inside the tank. Due to such thermal insulation, it is possible to reduce the temperature difference several times and eliminate drops.

Naturally, the situation with the condensate on the tank needs to be corrected. Otherwise, the consequences may be unfortunate. If you approach the solution comprehensively, then the situation will definitely improve.
