Common Toilet Leak #1

The most common toilet leak and often hardest to detect is caused by a deteriorated or defected flush valve (flapper) ball at the bottom of the toilet tank. If the flapper or ball valve does not seat properly and form a watertight seal, water will leak around it into the toilet bowl. Often, this leak will occur without being heard. To test this type of leak follow these simple steps:

  • Remove the tank lid, then flush
  • Wait for the flapper/tank ball to drop and the tank to refill
  • Add a few drops of food color or place a colored dye tablet, available at hardware stores, after the toilet has stopped filling
  • Wait at least 20 minutes
  • If any trace of the color appears in the toilet bowl then there is a leak

If the float is set too high and if the shut-off valve fails to close completely, water will continue to enter the tank and flow into the overflow tube, this type of leak can be seen by simply taking the tank top off and observing if the water is flowing into the overflow tube once the tank is full. Follow the following process to fix this type of toilet problem:

  1. Reset the tank water to a lower level by using the fill valve’s water level adjustment clip
  2. If it is a Float Cup-type valve, squeeze the two sides of the metal clip together, then slip the clip down the rod
  3. In the case of a Float Ball-type valve, lower the water level by bending float arm slightly downward.
