This Sloan A-1101-A Royal Water Closet Diaphragm Rebuild Performance Kit is designed specifically for use with Sloan Royal manual flushometers, providing a complete set of original OEM components to restore optimal flushing function. The kit includes a high-quality diaphragm, seals, and necessary hardware that directly replace worn parts in 1.6 GPF (gallons per flush) models. Each piece is manufactured to Sloan’s original specifications, ensuring precise fit and consistent performance without modification. The diaphragm material is formulated to resist mineral buildup and wear over time, maintaining reliable water seal and preventing leaks. The rebuild kit addresses common issues such as incomplete flushes, continuous running, or sluggish operation by refreshing the internal mechanism. Components are pre-sized and matched to the Royal flushometer design, simplifying the installation process for maintenance personnel. The sturdy construction of the included parts contributes to long-term durability in high-traffic commercial restroom settings.

This performance kit is suitable for facilities that require consistent water efficiency and minimal downtime. By using genuine OEM components, the rebuild avoids compatibility problems often associated with generic alternatives. The kit supports standard 1.6 GPF water conservation targets while delivering the same reliability as the original factory equipment. The rebuild process involves replacing the diaphragm assembly and related gaskets inside the flushometer valve. The included parts are engineered to withstand repeated hydraulic pressure cycles and exposure to chlorine or other treatment chemicals. The diaphragm is made from a reinforced elastomer compound that offers flexibility without premature cracking.

The kit also contains a new seat disc and spring to ensure proper sealing and reset action. Each component is individually inspected to meet Sloan’s quality control standards. This rebuild solution is intended for use with Sloan Royal manual flushometers installed in water closets (toilets) that require a 1.6 GPF setting. The kit does not alter the flush volume but restores the original factory performance. It is applicable for both new construction maintenance and retrofit of older flushometers. The materials used are free from common contaminants that could degrade water quality.

The design prioritizes ease of service, with clearly identified parts that fit directly into the flushometer body. Using this rebuild kit can help extend the service life of existing flushometers without the need for complete valve replacement, offering a cost-effective approach to restroom upkeep. The physical characteristics of the components include a flexible diaphragm with molded ridges for consistent water passage, a corrosion-resistant seat disc, and a stainless steel spring. The packaging is compact and labeled for quick identification during inventory management. The kit does not require special tools for installation, though basic knowledge of flushometer maintenance is assumed. The overall construction reflects Sloan’s reputation for robust commercial plumbing parts.

This rebuild kit is compatible with all standard Sloan Royal manual flushometer models that use the 1.6 GPF diaphragm configuration. It is not intended for use with electronic or sensor-activated flushometers. The kit’s performance benefits include reduced water waste from leaks and improved flush cycle consistency. The materials meet or exceed industry standards for potable water contact. The rebuild process is straightforward: remove the old diaphragm assembly, clean the valve interior, and install the new components in the reverse order. This rebuild kit provides an economical way to maintain restroom efficiency without upgrading to a new flushometer unit.
