If you listen to your toilet when you don’t want it to be flushed and you hear sounds that resemble a flushed toilet, you are likely to have a damaged fill valve.

Next, you will find the toilet float. It is either a plastic or rubber ball at the end of a metal arm or a cylinder mounted on a pipe.

If the float is a cylinder, you should find a mechanism to release it for change. Release it, lower the float, and make sure the mechanism clicks into place.

When you lower the water level, your toilet shouldn’t use more water than necessary. Close your toilet tank and make sure you put everything back where it came from. Give the toilet a test flush. If everything works properly, your problem is resolved.
