Running Toilet
A running toilet can waste hundreds of gallons a day. The cause is usually a worn flapper.
Supplies you’ll need
- ☐ Replacement flapper (match your toilet's brand)
- ☐ Towel and small bucket
- ☐ Sponge
- ☐ Food coloring for the leak test
Steps
- Do the dye test. Add a few drops of food coloring to the tank. If color shows in the bowl after 15 minutes, the flapper leaks.
- Shut off the water. Turn the valve behind the toilet clockwise, then flush to empty the tank.
- Remove the old flapper. Unhook it from the overflow tube ears and the chain from the flush lever.
- Install the new flapper. Clip it on the ears and attach the chain with about half an inch of slack.
- Restore water and test. Open the valve slowly, let the tank fill and flush twice, watching that the flapper seals.
Cleanup
- Sponge up spills around the base.
- Wipe the tank rim and rinse the dye with a flush.
Call a pro if…
- Water keeps running after a new flapper.
- You see leaks at the base or supply line.
- The shutoff valve will not turn or drips.
