3.1 Compatibility
This diaphragm assembly is specifically designed for use with Sloan Royal Flushometers. It is a 1.6 GPF (Gallons Per Flush) model for water closets. Always verify the GPF rating of your existing flushometer to ensure proper compatibility and function. Other Royal water closet diaphragm replacements are available in 1.28 GPF and 3.5 GPF, and urinal models in 0.125 GPF, 0.5 GPF, 1.0 GPF, and 1.5 GPF.
4. Installation Instructions
These instructions outline the general procedure for replacing a diaphragm assembly in a Sloan Royal Flushometer. Specific flushometer models may have minor variations.
- Turn off Water Supply: Locate the control stop on the flushometer (typically on the right side, as shown in Figure 3) and turn it clockwise with a screwdriver until the water supply is completely shut off. Flush the fixture to relieve any remaining pressure.
- Remove Flushometer Cover: Unscrew the top cover of the flushometer. This may require a spud wrench or similar tool.
- Remove Old Diaphragm Assembly: Carefully lift out the old diaphragm assembly from the flushometer body. Inspect the inside of the flushometer for any debris or mineral buildup and clean if necessary.
- Install New Diaphragm Assembly: Place the new Sloan Royal A-1041-A diaphragm assembly into the flushometer body, ensuring it is seated correctly. The green PERMEX diaphragm should face upwards.
- Replace Flushometer Cover: Screw the top cover back onto the flushometer body. Hand-tighten first, then use a wrench to secure it, but do not overtighten.
- Restore Water Supply: Slowly open the control stop by turning it counter-clockwise. Listen for water filling the flushometer.
- Test Flush: Once the water supply is fully restored, test the flushometer several times to ensure proper operation and check for any leaks.
5. Operation
The Sloan Royal A-1041-A diaphragm assembly operates automatically within the Royal Flushometer. When the flush handle is activated, it momentarily releases pressure above the diaphragm, allowing water to flow through the flushometer and into the water closet. Once the handle is released, pressure equalizes, and the diaphragm reseats, stopping the water flow after the predetermined 1.6 GPF volume has been delivered.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Sloan Royal Flushometer and its diaphragm assembly.
- Periodic Inspection: Periodically inspect the flushometer for signs of leaks or inconsistent flushing.
- Cleaning: If water quality is poor, mineral deposits can accumulate. Disassemble the flushometer (following installation steps 1-3) and gently clean the diaphragm assembly and flushometer body with a soft brush and mild soap. Avoid harsh chemicals.
- Genuine Parts: To extend the life and ensure the highest performance of your Sloan products, always use Sloan Genuine Parts for replacements. The A-1041-A is a genuine Sloan part designed and tested to Sloan specifications.
