How to Stop a Toilet from Running
Constant running water? Usually a $5 fix.
Time 15 minsDifficulty EasyTools Replacement flapper
The short version
- Remove the tank lid and look inside.
- Check if the flapper is sealing properly.
- Adjust the chain so it has a little slack.
- If the flapper is worn, replace it (they're universal).
- Check the fill valve if water keeps running.
What you need
Your car should already have all of this: a jack, a lug wrench, and a spare tire (usually under the trunk floor or mounted underneath). Check your owner's manual if you can't find them.
Directions
- Look inside the tank. Remove the lid and set it somewhere safe. Watch what happens when you flush.
- Check the flapper. The rubber flapper at the bottom should seal flat. If it's warped or cracked, that's your problem.
- Adjust the chain. The chain should have about half an inch of slack. Too tight and the flapper can't seal.
- Replace the flapper. Turn off the water, flush to drain, unhook the old flapper, and snap on a new universal one ($5 at any hardware store).
- Test it. Turn the water back on, let the tank fill, and listen. Silence is golden.
