Sloan SR-102 Flush Valve Diaphragm

Product Description

The SLOAN SR-102 is a replacement diaphragm for Sloan flushometer-style flush valves. The diaphragm is the core control component inside a flush valve body, regulating water flow during each flush cycle by flexing under differential pressure to open and close the valve. Over time, diaphragms wear, harden, or accumulate mineral deposits that cause weak flushes, phantom cycling, or continuous water flow. Replacing this diaphragm restores proper flush volume and shutoff performance. Installation is handled by licensed plumbers or experienced maintenance technicians on commercial and institutional plumbing fixtures.

This diaphragm is suited for commercial restroom applications where Sloan flush valves are installed on water closets or urinals. Sloan flushometers are common in schools, office buildings, hospitals, stadiums, and other high-traffic facilities. The SR-102 diaphragm corresponds to Sloan A156a service, making it a direct-service replacement for valves exhibiting flow or shutoff issues traced to diaphragm failure. No soldering or major pipe work is required, as diaphragm replacement is performed by disassembling the valve cover and inner workings at the fixture.

Key Features

• Direct replacement diaphragm for Sloan A156a flush valve service
• Restores proper flush cycle volume and positive shutoff
• Addresses common failure modes including continuous flow and weak flush
• Lightweight component at 0.074 pounds for easy handling during service calls
• Designed for commercial-grade flushometer valve bodies

Compatibility

Designed as a replacement diaphragm for Sloan flush valves under the A156a service classification. Confirm valve model and diaphragm type against the existing valve body before installation.

Installation Notes

Diaphragm replacement on flushometers is performed by qualified plumbers or trained maintenance personnel. Shut off the water supply to the valve at the stop before disassembling the valve cover. Follow IPC guidelines and the valve manufacturer service instructions for proper diaphragm seating and cover torque sequence. Inspect the relief valve, guide, and seat for wear while the valve is open, and replace associated kit components as needed.
