Sloan 7-5301188 Rubber Diaphragm Flush Valve Repair

Product Description

The SLOAN 7-5301188 is a replacement rubber diaphragm designed for Sloan Regal and Royal flush valves installed on closet and urinal fixtures. The diaphragm is a critical internal component that controls water flow through the flush valve body, seating and unseating to deliver a timed flush cycle. When a flush valve begins running continuously, fails to flush, or short-flushes, a worn or damaged diaphragm is a common cause. This part carries Sloan trade number A-156-A and weighs 0.602 pounds. Installation is performed by licensed plumbers or qualified service technicians during routine flush valve maintenance or repair calls.

This diaphragm is suited for commercial and institutional plumbing applications where Sloan Regal or Royal flush valves are in service. Common install environments include restrooms in schools, office buildings, healthcare facilities, and other high-traffic commercial settings. The part is sold individually and fits both closet and urinal valve configurations as noted in Sloan documentation for trade number A-156-A.

Installation Notes

Flush valve diaphragm replacement is typically performed by a licensed plumber. Before beginning, shut off the water supply to the flush valve at the stop valve and flush the line to relieve pressure. Disassemble the valve cover and inner body per the valve service procedure to access and swap the diaphragm. Verify the new diaphragm is fully seated before reassembling and restoring water supply to test for proper flush cycle and absence of leaks.
