What it is

The Fluidmaster Bottom Entry 1/2 Inch Adjustable Airgap Fill Valve is a toilet cistern fill valve supplied by Fluidmaster. It is a bottom entry design with a 1/2 inch connection, an adjustable setting and an integrated airgap in a plastic body. The valve refills the cistern after a flush and the airgap provides backflow protection at the inlet.

Before you order

  • Confirm the cistern takes a bottom entry fill valve rather than a side entry type.
  • Check the inlet connection is 1/2 inch to match the existing supply.
  • Verify there is sufficient clearance above and around the cistern for an adjustable bottom entry body.
  • Check the existing airgap arrangement, as the airgap is integral to this valve.
