Repair Leaks

There are a number of signs that a toilet needs some repairs, but many toilets leak without conspicuous indications of trouble.  The following are signs of a leaking toilet:


  • Jiggling the handle to make the toilet stop running
  • Sudden sounds coming from the toilet when it is not being used
  • Water running over the top of the over flow, this is a definite leak of the refill valve
  • If you observe water trickling down the side of the toilet bowl will after it has been flushed
  • Water dripping out of the refill tube into the overflow pipes
  • The "Phantom Flusher" appears.  This is when the toilet turns on for 15 to 20 seconds and the handle has not been touched

If you are still unsure if your toilet is leaking the following dye test will highlight silent leaks.  According to the American Water Works Association (AWWA), toilets are responsible for approximately 27 % of the water used in homes on a daily basis.  A silent leak that goes undetected can amount to as much as 700 litres of water per day.

The Dye Test

  • Remove the cover on the toilet tank and carefully set it aside so it can't be accidentally knocked over and cracked
  • Begin the dye test with clear water in the tank as well as in the bowl. Remove any "in-tank" bowl cleaners that colour the water. Place enough dye or food colouring in the tank water to give the water a deep color.

  • Wait 30 minutes and make sure nobody uses the toilet. In 30 minutes if you find any of the dyed water is now in the toilet bowl you can be sure that your toilet is leaking.

 NOTE: A properly operating toilet will store water in the tank indefinitely without any water running into the bowl.
