Sloan A-1106-A Royal Urinal Diaphragm Rebuild Kit - Chloramine

In this review the Sloan A-1106-A Royal Urinal Diaphragm Rebuild Performance Kit is evaluated for maintenance techs and facility managers who need a reliable, OEM-level repair part for 0.5 GPF Royal flushometers. The bottom line: this kit includes the key components and a Permex rubber diaphragm with a dual filtered bypass that resists chloramine, so it restores expected flush function and reduces repeat service calls. For those seeking a straightforward rebuild that fits the Royal line, it represents a practical, long-lasting solution.

Key Features

• DIAPHRAGM PERFORMANCE KIT: Contains the components required to rebuild a Royal 0.5 GPF flushometer so installations can be completed in a single service visit.
• PERMEX RUBBER DIAPHRAGM: The synthetic rubber diaphragm with dual filtered bypass helps maintain consistent flush performance and withstands chloramine in treated water.
• COMPATIBILITY CHECK: Designed specifically for Sloan Royal flushometers to ensure a proper fit and reduce diagnostic time during repairs.
• SLOAN GENUINE PARTS: Uses OEM components tested to Sloan specifications to extend product life and minimize future breakdowns.
• WATER-CONSCIOUS DESIGN: Built for a 0.5 GPF configuration to preserve water savings while restoring reliable operation.

Who It's For

The kit is ideal for plumbers, custodial staff, and building maintenance teams responsible for commercial restrooms that use Sloan Royal urinal flushometers set to 0.5 GPF. It is particularly useful when chloramine-treated water has been linked to diaphragm degradation and regular parts replacements are needed.

Those who should look elsewhere include owners of non-Royal flushometers, fixtures with different flow settings, or technicians who prefer complete valve assemblies instead of a diaphragm rebuild kit. Always verify flushometer model compatibility before purchasing.

Pros & Cons

Pros

• OEM-quality Permex diaphragm improves longevity and restores near-new flush performance.
• Kit includes the necessary parts for a complete diaphragm rebuild, making installation straightforward.

Cons

• Only compatible with Sloan Royal flushometers at 0.5 GPF, so it is not universal.
