Here is a clear step-by-step guide on how to replace a toilet flapper:
- Turn off the Water Supply:
- Locate the water supply valve behind the toilet and turn it clockwise to shut off the water flow.
- Remove the Tank Lid and Empty the Tank:
- Remove the lid from the toilet tank.
- Flush the toilet to drain as much water as possible from the tank. Hold the handle down to let most water exit.
- Disconnect the Old Flapper:
- Detach the chain connected to the flush lever arm.
- Unhook the flapper from the two pegs or tabs at the base of the flush valve.
- Clean the Flush Valve Seat:
- Feel and wipe the flush valve seat (where the flapper sits) to remove mineral deposits or buildup to ensure a proper seal.
- Install the New Flapper:
- Attach the new flapper onto the two pegs or tabs on the flush valve.
- Connect the flapper chain to the flush lever arm, leaving about half an inch of slack to prevent the chain from getting stuck.
- Turn the Water Back On and Test:
- Turn the water supply valve counterclockwise to restore water flow.
- Let the tank fill, then flush to test the new flapper.
- Adjust the chain length if needed.
- Replace the Tank Lid:
- Put the lid back on the tank once the flapper is working properly to stop leaks.
Replacing a flapper is an inexpensive, easy fix that can prevent a running toilet and save water.
