FLUIDMASTER Pro 45C Manual Flush Valve

The FLUIDMASTER Pro 45C is a manual flush valve designed for toilet installations. It operates with a diaphragm mechanism and carries the FLUIDMASTER brand. The unit is supplied new and classified under toilet accessories for bathroom plumbing.

Suited to standard 1.28 gpf toilet tanks

This valve fits toilets rated at 1.28 gallons per flush and uses an anti-siphon design. It is not intended for flushometer-style commercial bowls or dual-flush systems that require a different actuation method. Buyers needing a sensor-operated or battery-powered unit should look elsewhere.

1.28 gallons per flush consumption

The defining specification is the 1.28 gpf flow rate, which determines compatibility with the toilet tank. Match this figure to the fixture marking before purchase to ensure correct performance.
