Oatey PP83528 Flush Valve Seat Disc Screw-on

Product Description

The OATEY PP83528 is a screw-on style flush valve seat disc designed to restore proper sealing in toilet flush valves. The disc mounts directly to the flush valve seat using a screw-on connection, creating a watertight seal that stops running water and phantom flushes. This replacement component is sized to fit American Standard screw-on flush valve assemblies and is a standard service item for licensed plumbers and experienced DIYers performing toilet repair. The part ships in a compact blister-card package measuring 5.25 inches by 5 inches by 1.2 inches and weighs 0.09 pounds.

This seat disc is intended for residential toilet repair work where the original screw-on flush valve seat disc has worn, warped, or failed to seal. American Standard toilets using screw-on valve seat disc assemblies are the target application. It is typically installed during a flush valve rebuild or as part of a running-toilet diagnostic service call.

Installation Notes

Shut off the water supply to the toilet at the angle stop valve and flush to empty the tank before beginning work. A licensed plumber or qualified service technician should perform this repair in accordance with applicable local plumbing codes referencing IPC standards. Remove the old disc by unscrewing it from the flush valve seat, then thread the new disc on hand-tight before confirming full seating. Restore water supply and cycle the flush several times to verify the seal is holding before returning the fixture to service.
