How to Stop a Running Toilet

Sometimes having a toilet that won’t stop running is worse than having a toilet that won’t flush at all. When you discover that your toilet just keeps on flushing, it indicates that there is a problem inside your toilet tank. There are only a few things inside the tank that could be causing the toilet to malfunction and stay running.

A constantly running toilet is characterized by the loss of water and the tell-tale noise of the toilet tank refilling. The first thing you want to do when this happens is take off the lid of the toilet tank and look inside. You should notice a chain lifting a flapper when you flush the toilet, a plastic float connected to a valve, and an overflow tube. Once you have observed these elements, you are ready to make the necessary fixes to stop your toilet from running.

Steps To Fix a Running Toilet

  1. Reach into the tank and close the flapper with your hand. You may notice that the chain is catching on things or is wedged open. If so, fix what might be preventing the flapper from closing completely.
  2. Examine to see if what water in the tank is at the water line. If it is not, turn on the water valve all of the way.
  3. Adjust the valve and float by pulling up the float with your hand until the water stops. Once the water has reached around an inch below the overflow tube, you can adjust the float.
  4. Clean and replace the flapper or flush valve. The constant running may be due to a small leak in the tank. You can check by putting dye tablets in the tank and waiting to see if the color leaks into the bowl. If you determine this is happening, you will need to clean or replace the flapper completely. Remember to turn off the water to the toilet and flush excess water when you replace this part.
