Which Parts Can I Replace to Get My Toilet to Stop Running?

If you are pulling your hair out because your toilet won’t stop running, don’t despair! You’ve got the solution right at your fingertips. Of all the plumbing problems that homeowners face, a running toilet is one of the most DIY-friendly. A toilet isn’t super complicated, and you can generally narrow down your potential causes by looking at a few key parts.

Here is a handy DIY diagnostic checklist:


The Flapper

The flapper is a lot like it sounds- it’s a rubber piece that flaps up and down to control the flow of water into the toilet bowl when you flush. It’s made of rubber, and rubber will certainly deteriorate over time.

It’s possible that the flapper is cracked or broken, which will permit the water to keep on flowing, even though it is supposed to have stopped. If it’s not the flapper itself, the seal around the flapper may have disintegrated over time as well. Eittoilet-diagramher way, replacing this part will stop your toilet from running.

To see if this is the problem, simply press the flapper down. If the water stops, then problem has been discovered. Take the broken flapper with you to the hardware store to make sure that you’ve got the right piece. Installation instructions will be on the package.

The Fill Valve

Another problem might be a faulty fill valve. To get this fixed, shut off the water supply and unscrew the nut that holds the fill valve on, which is located behind the tank. Lift the faulty valve out and replace it with a new one.

You can adjust the fill height too. Depending on the age of your toilet, it might be a float (ball) valve or a cup valve. These mechanisms regulate the height of water in your toilet. If they aren’t working, the water won’t know to stop filling the tank.

Repair Fill Tube

The problem is that if the end of the fill tube is submerged, it can’t drain the water off into the overflow tube, creating a continuous flow of water in the toilet.

To replace this part, drain the water tank and flush water from the bowl after you’ve turned the water supply off to minimize leakage. The fill tube is the long tube that extends through much of the interior components in the tank. Unscrew that tube, lift it out and replace it with a new one.
