If the Leak Sentry/Leak Guard fill valve does not allow for the water to refill the tank, we suggest removing some slack from the chain.

Please follow these instructions for getting the correct chain tension:

  1. Turn off water and empty tank by flushing.
  2. Lift tank lever all the way up inside tank and hold it there.
  3. Pull Leak Sentry/Leak Guard chain until it lifts the float cup all the way up the fill valve shaft.
  4. Connect chain & clip with no slack in chain to the tank lever (See Diagram below)
