This image displays the complete Sloan 3308607 H-535 Flushometer Coupling Kit, which includes the 3/4 inch coupling, nuts, and washers. It is designed for connecting flushometer valves.

4. Setup and Installation

Follow these steps to properly install the flushometer coupling kit:

1. Turn Off Water Supply: Locate the main water shut-off valve for the fixture or the building and turn it off completely. Flush the toilet to relieve any remaining water pressure.
2. Remove Old Coupling (if applicable): If replacing an existing coupling, use a wrench to carefully loosen and remove the old coupling nuts and the coupling itself. Be prepared for residual water to drain.
3. Clean Connection Points: Thoroughly clean the threads on both the flushometer valve and the supply pipe. Remove any old sealant, debris, or corrosion to ensure a proper seal.
4. Install New Washers: Place one rubber washer into each coupling nut. Ensure they are seated correctly.
5. Position Coupling: Place the new 3/4 inch flushometer coupling between the flushometer valve and the supply pipe.
6. Attach Coupling Nuts: Thread the coupling nuts onto the flushometer valve and the supply pipe, hand-tightening them first.
7. Tighten Connections: Using a wrench, carefully tighten both coupling nuts. Do not overtighten. The goal is a snug, leak-free connection.
8. Restore Water Supply: Slowly turn the main water supply back on.
9. Check for Leaks: Inspect all connections for any signs of water leakage. If leaks are present, gently tighten the nuts further until the leak stops. If a leak persists, turn off the water, disassemble, inspect washers for damage, and reassemble.

5. Operation

Once installed, the flushometer coupling kit functions passively to provide a secure and sealed connection between the flushometer valve and the water supply. Proper installation ensures the flushometer operates as intended without leaks.

6. Maintenance

The flushometer coupling kit requires minimal maintenance. Periodically inspect the coupling and connections for any signs of wear, corrosion, or leaks. If any issues are observed, turn off the water supply and replace the affected components as necessary. Avoid using harsh chemical cleaners on the coupling, as this can degrade the material.

7. Troubleshooting

• Leak at Connection:
  • Ensure coupling nuts are sufficiently tightened (do not overtighten).
  • Verify that the rubber washers are correctly seated and not damaged. Replace if necessary.
  • Check for any debris on the sealing surfaces that might prevent a proper seal.
• Difficulty Tightening Nuts:
  • Ensure threads are clean and free of cross-threading.
  • Verify the coupling and nuts are correctly aligned.
