Fixing A Running Toilet


All of us should do our part to conserve water. One of the biggest contributors to water waste is a running toilet. Many of us tend to ignore a running toilet until we receive the water bill. Ignoring a running toilet can waste more than 10,000 gallons of water annually. It will also put a dent in your wallet.

There are several factors that could be causing a toilet to run. Below are the most common reason for a running toilet and ways to fix them:


The flapper is usually the most common reason for a running toilet. After flushing the toilet, if you notice water that continues to run the flapper is more than likely the culprit. If this occurs, lift the lid off of the toilet, and push down on the flapper. This will close the flapper. If the problem persists check the following:

  • Is the chain catching itself to the flapper? If so shorten it.
  • Has the hinge of the flapper come loose? If so reattach it.
  • Does the flapper align with the opening? If not adjust it.
  • Is the flapper seal worn? You may need to replace it.

If you have to replace the flapper first turn off the water valve to the toilet. Next, flush the toilet to empty the excess water from the tank. Remove the flapper by detaching it from the chain, and popping it from the hinges.

Make sure you purchase the correct flapper to replace the old one. To install the new flapper follow the above process in reverse. Once completed, turn the water back on and test the flapper by flushing the toilet and make adjustments to the chain length as needed.


Though the flapper is the most common culprit for causing a toilet to continuously run, the valve and float might also be a contributor. Below are some troubleshooting tips:

  • Does the float seem to be low? Try pulling it up with your hand. If this does the job and stops the flow of water, manually adjust the float level. Adjust it around one inch from the very top of the overflow tube.
  • Does the float ball have a hole? If so it may be waterlogged and causing the water to overflow, even if everything else is functioning correctly. You will want to replace the float ball.
  • Does pulling up on the float ball do nothing to stop the water from running? If this occurs you may be in need of a new refill valve assembly. We recommend you turn off the water valve to the toilet and contact a Jacksonville Plumber.
