Repair parts and accessories for commercial flushometers: diaphragm and repair kits, vacuum breakers, handle assemblies, stops, flange kits, spuds and urinal parts. Over 95% of what is stocked here is commercial-grade.
The diaphragm is what fails. It is a rubber membrane that opens and closes the valve on each actuation, and as it hardens or perforates the valve either runs continuously or fails to deliver a full flush. Replacing it is a ten-minute job and restores the valve, which is why a rebuild kit is almost always the answer rather than a new flushometer.
Match the flush volume, not just the model. Flushometers are built for specific gallons per flush — 1.28, 1.6 and 3.5 all appear here, plus dual-flush and 0.125 gpf urinal versions — and fitting a kit of the wrong rating changes the fixture's water use and can break its WaterSense listing.
The vacuum breaker is a code-required backflow device, not an optional part; a missing or split one fails inspection.
Brands include Sloan, Zurn and American Standard.
