Why Is My Toilet Running Constantly? Causes and Fixes

That endless trickle from your toilet isn't just annoying. A running toilet can waste up to 200 gallons of water a day, quietly inflating your water bill. The good news is that the cause is usually one of a few simple parts.

The flapper

The most common cause is a worn or warped flapper, the rubber seal at the bottom of the tank. When it no longer seals, water leaks into the bowl and the tank refills endlessly.

The fill valve

If the fill valve doesn't shut off at the right level, water runs into the overflow tube continuously. Adjusting or replacing the valve usually solves it.

The float

A float set too high tells the tank to keep filling past the overflow line. Lowering it stops the overflow.

The chain

A chain that's too short or tangled holds the flapper slightly open. A quick adjustment often fixes it.
