How to get rid of condensation on a toilet cistern

Note that modern toilet cisterns sometimes have double walls. There is a plastic container inside, its walls do not touch the ceramic surface of the sanitary ware. This completely prevents the risk of condensation on the outer walls. However, such tanks are several times more expensive than ordinary ones, and they are not yet found everywhere. Therefore, most owners use simple devices, on the walls of which condensation often appears..

How to get rid of condensation on a toilet cistern

Having decided that it is useless to deal with condensation on the tank, or considering it a completely normal phenomenon, many take only temporary measures – they put a rag under the toilet bowl, put some kind of vessel to collect drops of water and periodically wipe the faience walls of the container. This is fundamentally wrong and can only make the problem worse..

There are already many sources of moisture in the bathroom and toilet, condensation will lead to the appearance of an unpleasant odor of dampness, mildew and mold, puddles on the floor, rust on metal pipes, fixtures and other parts. In the end, with a strongly “sweating” tank, you can even flood your neighbors, because an uncleared puddle on the floor will seep down.

The main reason for the appearance of condensation on the tank is the difference between the temperature of the water inside and the temperature of the air in the room..

If the water in the tank is 10–15 ° C colder than the air in the room, drops of moisture will appear on the walls! Now let’s look at more specific causes of condensation and ways to eliminate them:

  1. Fault in the drain tank. If water is constantly flowing into the toilet, getting into the cistern over and over again, of course, it simply does not have time to heat up and remains cold. So much for the condensation on the walls. We wrote in detail how to repair the drain fittings of the toilet tank with our own hands, so you can eliminate this reason;
  2. In addition, the lack of ventilation in the bathroom, increased humidity in the room can cause condensation. For the same reason, the windows in the house “cry”, you should take care of the presence of forced ventilation in the bathroom, perhaps leave the door to this room without a window open in order to ventilate and get rid of excess moisture;

  1. Cold water may also remain in the reservoir due to excessive use. If the water is constantly rinsed out, it will also not have time to warm up to room temperature. It is more difficult to deal with this problem, because in a large family a bathroom is a very often visited place. Alternatively, you can use the minimum drain button, if there is one on the tank. You can reduce the pressure of the water entering the tank by slightly tightening the tap;
  2. Often homeowners note that condensation on the toilet cistern appears exclusively in winter. This is easily explained – in winter the water coming directly from the street will be really ice cold. The owners of private houses can be advised to do additional insulation of the water supply system, but this does not always help. A simple way is to ensure that warm, heated water is supplied to the tank. But not hot in any way, we warn you, this is harmful to the fittings inside! Providing warm water will permanently save you from condensation, but will lead to additional costs;

  1. Contradictory results in the fight against condensation, judging by the reviews, are given by the insulation of the toilet tank from the inside, thermal insulation. For this purpose, you can use insulation with a layer of foil, but over time, constantly wet insulation can begin to fall off and clog the valves. They insulate the tank from the inside and with foam, this reduces its volume, but helps the cold water not to come into contact with the walls;
  2. If you cannot heat the water in the tank to room temperature, you can lower the temperature in the bathroom itself by turning off the heating. This method, of course, is not for everyone, because very few people will agree to freeze in winter, sitting on a “faience friend”.

We state: it is guaranteed that you can get rid of condensation in the bathroom by replacing the tank with a more modern model with double walls and connecting the warm water supply. Other methods can work if the cause has been precisely found, for example, a malfunction of the drain valve or high humidity in the room..
