American Standard 985969 Flush Valve Diaphragm 3-pack

Product Description

The American Standard 985969 is a replacement flush valve diaphragm packaged in a set of three, designed for use in American Standard Cadet series toilets. The diaphragm controls water flow during each flush cycle by sealing and releasing the flush valve at the correct pressure differential. When a diaphragm wears, cracks, or loses flexibility, the result is a running toilet, incomplete flush, or failure to refill. This OEM-style replacement restores proper flush valve function without the need to replace the entire flush valve assembly. Licensed plumbers and experienced service technicians are the primary installers of this part.

This diaphragm kit is suited for residential plumbing applications where American Standard Cadet toilets are installed. The three-unit pack makes it practical for multi-unit residential buildings, property maintenance accounts, or service contractors who handle repeat Cadet toilet repairs. It is a direct-fit replacement intended to return the flush valve to original operating condition.

Key Features

• Three diaphragms included per package, reducing per-unit cost for repeat service calls
• OEM-style fitment designed for American Standard Cadet series flush valves
• Restores proper flush cycle pressure differential and water shutoff after flushing
• Addresses common symptoms including phantom running, weak flush, and slow refill

Compatibility

Designed as an OEM-style replacement diaphragm for American Standard Cadet series flush valve assemblies. Verify flush valve model before installation to confirm fitment.

Installation Notes

Shut off the water supply to the toilet at the stop valve before beginning service and flush to drain the tank. Diaphragm replacement in a flush valve is a standard plumbing repair performed by licensed plumbers or qualified maintenance technicians. Remove the flush valve cap per the valve manufacturer's procedure, seat the new diaphragm correctly, and restore water supply before testing flush function. Do not overtighten the valve cap, as this can distort the diaphragm and cause immediate leakage.
