Here are a few things you can check to stop a running toilet:
- For older toilets: Check to see if the problem is with the float ball. If the float ball is stuck in the up position, it could be causing the water to continuously run. Simply push down on the float ball until it is in the correct position.
- If the problem is with the flapper, try adjusting it. The flapper is what keeps the water from running out of the tank. If it is not positioned correctly, it could be letting water escape. Try moving it around until it forms a seal.
- There could also be a problem with the fill valve. This is what allows water into the tank. If it is not working properly, it could be causing the toilet to run constantly. Try cleaning it or replacing it if necessary.
- The water level in the tank could be too high. All fill valves have an adjustment level for the fill valve float. In the center of the tank, there is an overflow tube that should be approximately 1” above the water level. If there is water running into that tube, the water level is too high. If this is what you are seeing in your toilet tank, you will need to adjust the fill valve float.
