Repair when Flushing

Toilet Bowl will not fill after the Flush

Toilets that do not refill the bowl after the flush are mainly a fill valve issue. Here are some simple solutions that you can try to fix this problem.

  1. Check that the refill tube is attached to the top of the overflow pipe
  2. Check Bowl Refill adjustments are set properly for water dispensing into bowl after a flush
  3. Flushing Debris from fill valve
  4. Replace / repair the fill valve

 A. The Refill Tube delivers water directly to the toilet bowl with every flush. Make sure the tube is dispensing water directly into the overflow pipe. The refill tube needs to be set on a clip set above the pipe and not shoved directly inside the pipe or a siphon will occur, causing the toilet to turn on and off like a ghost flush.

B) The Fluidmaster 400H-002 fill valve has a Bowl Refill Knob that lets more or less water go into the bowl – if you are using a 400H-002 from Fluidmaster make sure this adjustment is set properly.
