Bathrooms are a modern convenience when they are working properly, but they are a modern nuisance when they are not. A dump valve is a relatively simple mechanism, but when it starts to malfunction, it is difficult to repair, especially since many homeowners never look toward the back of their toilet until something goes wrong and they really do not know how the water works. toilet.

Partial closure
If the discharge valve closes only to a certain point, your toilet will probably continue to run and waste of water. Check that nothing is blocking the discharge valve and keep it open and that the toilet tank cover is not obstructing the movement of the discharge valve.
damaged joint
A damaged gasket or crack or hole in the tank below the discharge valve will lead to the same symptoms as a discharge valve that will not close: you will hear running water in the toilet when it should not. Inspect the discharge valve and the area around it for damage or something unusual, which could include cracking or discoloration of the porcelain, interference or obstruction by foreign objects or broken or bent mechanisms.
Bent ball tank
Tank balls were replaced with fins many years ago, but, if you have an old toilet, you can still have a tank ball, which is a plastic or metal sphere attached to a rod. The tank ball floats on the surface of the water in the toilet tank and lifts a lever that closes the discharge valve when the tank is full. If the rod to which the tank ball is attached is bent so that the tank ball is too low, the water stops before the tank is full. If the tank ball is too high, the water keeps running in the overflow tube because the mechanism has not told it to stop.
Flooded Fin
If you have a new toilet, your toilet has a flap valve instead of a tank ball. If you are having problems with the discharge valve, the fault lies most likely to be the trap. If the flap valve becomes saturated with water, it may fail to seal the outlet pipe and the water will continue to run outside the pipe, preventing it from shutting down. Replacing the flooded fin with a new one will solve this problem.
