The Sloan A-1108-A Royal Urinal Diaphragm Rebuild Performance Kit is an OEM replacement assembly designed specifically for Sloan Royal flushometers. This kit contains all necessary components to restore the flushing mechanism of urinal flush valves, featuring a chloramine-resistant diaphragm that withstands aggressive water treatment chemicals. The diaphragm serves as the core sealing element, controlling water flow and ensuring consistent 1.5 gallons per flush (GPF) operation.

Constructed from high-grade synthetic rubber compounds, the diaphragm resists swelling, cracking, and degradation over extended service periods. The kit also includes a new handle, cap, and gaskets, providing a complete rebuild solution for maintaining original performance standards. Each component is manufactured to Sloan’s original specifications, guaranteeing precise fit and reliable function with Royal series flushometers. The chloramine-resistant formulation addresses the common issue of premature diaphragm failure in municipal water systems that use chloramine disinfection. This resistance prolongs the service life of the kit, reducing the frequency of maintenance and replacement. The 1.5 GPF rating meets water conservation requirements while delivering sufficient flush volume for effective waste removal. The kit’s construction emphasizes durability: the rubber parts are molded with controlled thickness to prevent tearing, and the metal handle is plated for corrosion resistance. The rebuild kit is suitable for commercial and institutional restrooms where Sloan Royal flushometers are installed. It is intended for use by facility maintenance personnel or experienced plumbers. Installation requires basic tools and follows standard procedures for disassembling the flushometer. Once installed, the kit restores smooth manual or sensor-activated flushing, eliminating leaks and incomplete flushes. The kit does not alter the flush volume beyond the original 1.5 GPF specification, maintaining compliance with plumbing codes. The use of genuine OEM parts ensures that warranty and performance guarantees remain intact. Beyond the diaphragm, the kit includes a new vacuum breaker and sealing washers, addressing all critical wear points. The vacuum breaker prevents back-siphonage, safeguarding water quality. The rebuild process eliminates common issues such as running water or weak flush, restoring the fixture to like-new condition. The components are packaged with clear instructions for straightforward replacement. Priced affordably at $44.84, this performance kit offers significant value compared to purchasing individual parts or hiring a plumber for repairs. Its availability as a complete set saves time and ensures all necessary pieces are on hand. For facilities managing multiple restrooms, stocking this rebuild kit enables quick turnaround on flushometer maintenance. The chloramine-resistant diaphragm gives added reliability in systems with chemically treated water. The kit’s original equipment design means no modifications or adapters are needed—direct replacement for worn parts. Consistent OEM quality reduces the risk of future failures and extends the interval between rebuilds. The 1.5 GPF configuration balances water savings with effective flushing, making it an upgrade for older fixtures that may have used higher volumes.

This rebuild kit is a practical investment for maintaining sanitary and efficient urinal operations.
