Toilet Flappers Toilet Flappers

Toilet flappers are the part of the toilet system that separates the flushing water in the tank from the bowl.

Toilet flappers are usually made of rubber, and act as a seal when the flush is not in operation. When the flush is operated, the flapper lifts up and allows the water into the bowl.

How can you tell if toilet flappers are faulty?
Lift the lid of the tank and drop a few drops of colored food dye into the tank. If the water in the bowl changes color before the flush has been operated, the flapper is faulty because it has leaked and let water through. 

It is essential to replace defective toilet flappers because otherwise the water wasted can cost the homeowner hundreds of dollars per year. Toilet flappers are damaged by bleach and “in-tank” tablets, so these should be avoided to prevent further damage.

Replacing toilet flappers
Replacing toilet flappers is simple as long as you follow two simple instructions:

  • Turn off the water supply to the toilet before you start the repair job.
  • Check that you purchase the right flapper for your toilet. You should find details of the make on the inside of the toilet tank.
  • Flappers vary in the way in which they are fitted, so make sure that you follow the manufacturer’s instructions.
