Troubleshooting the Toilet Flapper

Phil Laprairie

Troubleshooting the Toilet FlapperIf the toilet in your Calgary home isn't flushing properly, is running continuously or making whining or dribbling sounds, a flapper issue is most likely to blame. The flapper is the rubber device at the bottom of the toilet tank that opens when you flush to allow water out and closes to allow the tank to refill. Below are some tips you can use to troubleshoot toilet flapper problems.

Readjust the Flapper

For proper flapper operation, the chain or wire that attaches it to the flush lever should be fairly straight when the flapper is seated on the flush valve seat.

  • Remove the toilet tank lid and evaluate the chain's length. If it's too short, it won't allow the flapper to fit properly on the valve seat. If it's too long, it may flop into the valve, preventing the flapper from sealing properly.
  • Lengthen or shorten the chain or wire by moving it to a different hole in the bar at the top of the tank.
  • Flush the toilet to see whether the problem has been solved.

Clean the Flapper

If the toilet problem persists, you'll need to check for scale and mineral buildup on the flapper and valve seat.

  • Turn off the water valve behind the toilet.
  • Flush the toilet to empty the tank.
  • Use a cloth then a scouring pad to gently clean the flapper and the edges of the valve seat.

Replace the Flapper

If you still experience problems after taking the steps above, it's probably time to replace your toilet flapper.

  • Lift the flapper and carefully examine its surface. If it's warped, pitted or corroded, you should replace it.
  • Check the valve too. It's a good idea to replace it if you spot signs of deterioration so as to protect yourself from potential problems such as leaks.
