What to do when the toilet tank is leaking while the toilet tank is filled with water

There are three scenarios for a leaky toilet:

1. The water leakage at the water inlet of the water tank, the water leaks to the toilet, the solution is to remove it to see if the rubber pad has been damaged, if no harm is found, you can try to change the direction of the rubber pad to install it. If it doesn't work, then you can only replace the rubber pad;

2. The rubber pad of the valve seat of the flush valve leaks and leaks into the toilet, and the method is the same as above;

3. The toilet is cracked, some slightly cracked, just a slight water seepage, the crack is not easy to see, the situation you said should be more serious, so the cracking is relatively rare, it should be a situation, because you did not mention the location of the water leakage, as soon as you know the location of the water leakage, you can judge the source of the problem. Hope it helps.

That is, the flush valve seat gasket is damaged and leaking (the black part in the picture), you need to take it out to see if you can adjust the deformation direction down to use, if not, you need to replace it.

1. The rubber ball valve is broken, the seal is not tight, and there is water leakage, as long as it is replaced.

2. The rubber gasket of the drain port under the ball valve is aging and the sealing is not tight, so it needs to be replaced.

3. The connection between the spherical float of the water tank and the water inlet switch is loose, the float is in place and the switch is not closed, resulting in the water inlet does not stop, and the water flows out from the upright discharge pipe after the water is full, as long as the connection between the float and the water valve switch is tightened.

1.If you are using a new toilet, check that the following rubber ball valve is firmly installed when it touches the water tank.

2.If the rubber ball valve is installed tightly, please check whether there is any crack in the water tank and repair the crack.

Judging by your description, I feel like you need to confirm a point, where did the water leak from?

Water dripping down from the valve of the toilet bowl is due to the aging of the rubber from the inlet and must be replaced.

If the water is flowing from the toilet, there are two places that need to be checked, the first is the rubber stopper for draining the water, and the second is the body of the overflow pipe.

The rubber pad at the water inlet is aging, so try replacing it with a rubber pad.

Turn off the water inlet, wait for the water to leak, take off the cover to operate, slowly turn the drain one, turn it to a certain angle to take it off, use a screwdriver to remove the drainage, and then slowly reinstall it back, fix the direction of the iron bar to be perpendicular to the wall, and touch the rubber pad below with your hands after tightening, whether it is tighter.

Then put the drain back on. The process should be careful. Fill up with water. Look at the effect.

There is also the two rods above the lid, do not directly resist the accessories below the drainage. TO RESERVE 2-3MM AND GENTLY PRESS IT TO FEEL IT.

I hope to do it myself.
