This Sloan A-1102-A Royal Water Closet Diaphragm Rebuild Performance Kit is an OEM-grade service set designed for use with Sloan Royal flushometers. The kit includes a chloramine-resistant diaphragm, valve seat assembly, and all necessary hardware to restore the flush valve to full working condition. The 3.5 GPF (gallons per flush) configuration matches standard commercial water closet applications, ensuring consistent flush volume and reliable operation over extended service intervals. Each component is manufactured from high-durability materials that withstand the corrosive effects of chloraminated water supplies, reducing the frequency of maintenance and replacement cycles.

The diaphragm in this kit features a reinforced design that maintains its sealing integrity under varying water pressure conditions, preventing leakage and irregular flushing. The valve seat is precision-machined to create a secure seal with the diaphragm, minimizing water waste and noise during operation. All parts are sourced directly from the original equipment manufacturer, guaranteeing dimensional accuracy and compatibility with existing Sloan Royal flushometer bodies. The kit supports straightforward installation using common tools, allowing facility maintenance personnel to complete the rebuild efficiently without specialized training.

Performance characteristics include consistent 3.5 GPF delivery across the rated pressure range, with the diaphragm responding reliably to handle actuation. The chloramine-resistant formulation extends the life of the components in municipal water systems that use chloramine disinfection, a common concern in many regions. The kit does not require routine lubrication or adjustments after installation, operating quietly and reliably through thousands of flush cycles. The hardware included – mounting screws, washers, and gaskets – are corrosion-resistant and manufactured to tight tolerances.

This rebuild kit is appropriate for commercial restroom environments such as office buildings, schools, hospitals, and public facilities where Sloan Royal flushometers are installed. The 3.5 GPF standard water usage complies with many local plumbing codes for water-efficient fixtures, and the kit restores the flushometer to its original manufacturer specifications. The OEM designation ensures that the rebuild matches the factory performance, avoiding compatibility issues that can arise with generic aftermarket parts. The kit’s components are individually packaged to protect against contamination prior to installation.

The overall build quality and material selection reflect Sloan’s engineering standards, providing a durable solution for maintaining flushometer performance at a cost significantly lower than replacing the entire unit. The kit offers a practical balance between reliability and affordability, making it a common choice for proactive plumbing maintenance programs. By replacing only the wear-prone internal parts, the rebuild approach extends the service life of the existing flushometer body, reducing material waste and labor costs associated with full replacements. This performance kit is a straightforward way to keep Sloan Royal flushometers operating at their peak efficiency.
