Fill valves

What a toilet fill valve does, and how it differs from the flush valve.

A fill valve admits supply water into the cistern and shuts it off at a set level. It is the inlet, not the outlet. The outlet is the flush valve.

Specifications and certifications are confirmed on request.

What to look for

  • The valve should stop the inlet when the float reaches the chosen line.
  • A tank that never goes quiet can be a fill-valve issue, a water line set above the overflow, or a flush valve that is not sealing.
  • Debris in the supply can reach the inlet after other plumbing work.

Replacement and water-level notes are on the guides page. Choosing between a side inlet and a bottom inlet is in side-entry vs bottom-entry fill valves.
