What is the most common cause of a running toilet leak?

The most common cause of a running toilet is a worn or mis-seated flapper that lets water leak from the tank into the bowl. A sticking fill valve or an incorrect float level can also keep the water running. We handle toilet repairs across Roanoke, Cave Spring, and nearby areas.

Quick checks:

  • Do a dye test in the tank; color in the bowl points to the flapper.
  • Make sure the chain has slight slack.
  • Inspect the flapper and clean the seat.
