Sloan A-1102-A Royal Water Closet Diaphragm Rebuild Performance Kit

In this review the Sloan A-1102-A Royal Water Closet Diaphragm Rebuild Performance Kit is judged as a targeted repair solution for facility maintenance staff and plumbing professionals who need a dependable rebuild for Royal flushometers. The kit's single biggest reason to buy is its inclusion of genuine Sloan components built around a PERMEX synthetic rubber diaphragm that resists chloramine, which means fewer repeat repairs and restored flushing performance for 3.5 GPF Royal flushometers. The review explains real-world fit, installation ease, and value based on customer feedback.

Key Features

• Complete rebuild kit: Contains all the parts required for a full diaphragm rebuild so technicians can complete the repair in one visit.
• PERMEX rubber diaphragm: The synthetic rubber diaphragm is formulated to resist chloramine, reducing premature degradation in treated water systems.
• Designed for 3.5 GPF Royal flushometers: Specifically matched to Sloan Royal models that use 3.5 gallons per flush for reliable compatibility and performance.
• Genuine Sloan parts: Original OEM components extend product life and help maintain manufacturer performance and warranty expectations.
• Maintenance-focused design: The diaphragm includes a dual filtered bypass to promote consistent flow and reduce clog-related issues over time.

Who It's For

This kit is best for building maintenance teams, service plumbers, and facility managers responsible for commercial restrooms that use Sloan Royal flushometers at 3.5 GPF. It suits those who prefer OEM replacements to ensure long-term reliability and straightforward compatibility checks before ordering.

It is less suitable for residential toilet repairs or non-Royal flushometer brands; if a facility uses a different flushometer family or an alternate flush volume, customers should verify part compatibility or choose a kit matched to their specific model.

Pros & Cons

Pros

• Chloramine-resistant PERMEX diaphragm reduces the need for frequent replacement in treated water systems.
• Customers report easy installation and that the kit includes everything needed for the repair.

Cons

• Only compatible with Sloan Royal flushometers at 3.5 GPF, so buyers must confirm model fit before purchase.
