The toilet cistern can leak, as can be seen from the characteristic ripples of water in the bowl. The leak is usually not critical, but since it never stops, cubic meters of water just go down the drain in a month. Therefore, the problem needs to be addressed. Often it is not necessary to change the internal fittings of the tank, but it is enough to service the toilet by doing just 2 simple things.
The process of repairing a leaking toilet cistern
The first step is to remove the tank lid, shut off the water supply and press the drain. After that, you need to remove the drain fittings on which the button is located. To do this, you need to grab it with your hand, and make a half turn counterclockwise.
Now you need to remove the reinforcement, and rinse the sealing gum located on it below from plaque.
It is also necessary to unscrew the plastic fastener from the tank, in which it is fixed. Under it, ceramics are cleaned from plaque.
After that, the plastic mount is screwed into place, and the drain snaps onto it. It is also necessary to change the adjustment of the lateral filling fitting with a float. Perhaps it is simply drawing more water into the tank than the drain level allows.
To do this, you need to lower it one division down.
After cleaning and adjusting, water will not be able to ooze out under the seal and collect above the level of the drain tube.
This will help eliminate the leak. This method almost always helps, except in cases where the seals are simply hardened and no longer fit without gaps. Then only their replacement will help.
