How To Fix A Running Toilet Yourself


Fixing a running toilet is a common plumbing issue that you may be able to solve yourself. If you feel this is over your head or you don't have the proper tools, feel free to reach out to us for expert help.


Here are the general steps to follow:

  1. Check the flapper valve. The flapper valve is the rubber or plastic piece at the bottom of the tank that controls the water flow into the bowl. If it's worn or damaged, it can cause water to leak into the bowl, which can cause the toilet to run constantly.

  2. Adjust the flapper chain. If the chain connecting the flapper valve to the toilet handle is too loose or too tight, it can cause the toilet to run. Adjust the chain so that there's a little bit of slack, but not too much.

  3. Check the fill valve. The fill valve is the mechanism that refills the tank after you flush the toilet. If it's not working properly, it can cause the toilet to run. Make sure that the valve is fully open and that the float arm is in the correct position.

  4. Clean or replace the fill valve. If the fill valve is dirty or worn, it can cause the toilet to run. Remove the valve and clean it with vinegar or replace it if it's damaged.

  5. Check the overflow tube. The overflow tube is the vertical tube in the middle of the tank. If it's not positioned correctly, it can cause the toilet to run. Make sure that the water level in the tank is below the top of the tube.

  6. Test the toilet. Turn on the water supply and flush the toilet to make sure it no longer runs.
