How To Get A Toulet To Stop Running

As a passionate homeowner, I know how frustrating it can be to deal with a running toilet. The constant sound of running water, not to mention the increased water bill, can be incredibly bothersome. However, fear not! With a few simple steps, you can troubleshoot and fix a running toilet all by yourself.

Gather Your Tools

Before you begin, make sure you have the necessary tools at your disposal. You’ll likely need a pair of gloves, a sponge, a bowl, and adjustable pliers. These will come in handy during the troubleshooting process.

Identify the Problem

First things first, you’ll need to identify what’s causing the toilet to run. Often it’s a faulty flapper or a fill valve that needs adjusting. Remove the tank lid and inspect the components inside. It’s important to note that the water in the tank is clean but may contain cleaning chemicals, so be cautious.

Check the Flapper

Inspect the flapper to see if it’s not sealing properly. Over time, the flapper can deteriorate or become misaligned, causing water to leak into the bowl. If you notice any damage, it’s time to replace the flapper. Make sure to turn off the water supply before proceeding with the replacement.

Adjust the Fill Valve

If the flapper seems to be in good condition, the issue could be with the fill valve. This component is responsible for refilling the tank after each flush. Adjust the float of the fill valve to ensure the water stops at the correct level. This can often solve the problem of a constantly running toilet.

Take Action

Once you’ve identified the issue, it’s time to take action. If you need to replace the flapper or adjust the fill valve, carefully follow the manufacturer’s instructions. It’s a good idea to have a towel handy to clean up any water that may spill during the process.

Test and Adjust

After making the necessary repairs or adjustments, it’s time to test the toilet. Flush it and observe if the problem has been resolved. If the toilet continues to run, you may need to repeat the steps and double-check the components for proper installation.


By following these simple steps, you can save yourself the hassle and cost of hiring a plumber to fix a running toilet. Troubleshooting and fixing household issues can be empowering and save you money in the long run. Remember, always prioritize safety and turn off the water supply before working on any plumbing components. Happy fixing!
