The Sloan A-1001-A Regal Water Closet Diaphragm Rebuild Performance Kit is a comprehensive repair solution designed specifically for Sloan Regal flushometers. This kit contains genuine OEM replacement parts, ensuring compatibility and reliable performance for 4.5 GPF valve models. The included chloramine-resistant diaphragm offers extended service life by resisting degradation from chloramine-treated water supplies commonly found in commercial and institutional plumbing systems. Each component is precision-molded to original specifications, providing a seamless fit without modifications.

The kit features a full diaphragm assembly, seat disc, guide, spring, and necessary hardware for a complete internal overhaul. By replacing worn internal parts, this rebuild kit restores flushing efficiency and helps prevent common issues such as running water, incomplete flushes, or valve leaks. The diaphragm material maintains flexibility over time, preserving consistent water flow without premature wear. Designed for straightforward installation, the kit allows facility maintenance personnel to restore flushometer performance without specialized tools.

The 4.5 GPF rating suits older plumbing systems where lower gallon-per-flush models may not be appropriate, making this an ideal maintenance upgrade for existing Sloan Regal fixtures. With OEM-grade rubber compounds engineered for cold water applications, the rebuild kit delivers dependable operation under continuous use. Regular replacement of diaphragm components as part of preventive maintenance can extend the lifespan of the flushometer and reduce water waste.

The affordability of this kit compared to purchasing a new valve body makes it a cost-effective solution for large facilities. Each part is tested to meet durability standards, ensuring that the rebuilt flushometer performs reliably through thousands of cycles. The kit does not include chemicals or additives but relies on robust mechanical design to achieve consistent results.

Its compatibility extends across multiple Sloan Regal models, simplifying inventory management for maintenance departments. The chloramine resistance is particularly valuable in areas where water treatment chemicals accelerate rubber deterioration, providing an additional layer of reliability. Whether refurbishing a single restroom or performing routine maintenance across a building, this performance kit offers a practical and economical approach to keeping flushometers in optimal working condition.
