5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Sloan Regal 111 Flushometer.

5.1 Routine Cleaning

Clean the polished chrome exterior with a soft cloth and mild, non-abrasive cleaner. Avoid harsh chemicals or abrasive tools that could damage the finish.

5.2 Diaphragm and Internal Components

The flushometer's diaphragm and internal components are crucial for its operation. If the valve experiences issues such as continuous flushing or weak flush, it may indicate a need to inspect or clean these internal parts. The control stop plug allows for easy shut-off of water to the unit for servicing. Refer to the detailed service manual for specific instructions on disassembling and reassembling internal components.

6. Troubleshooting

If you encounter issues with your flushometer, consider the following common problems and solutions:

• Continuous Flushing: This can often be caused by debris or sediment in the inlet valve or a worn diaphragm. Turn off the water supply at the Bak-Chek angle stop, disassemble the top cover, and inspect/clean the diaphragm and valve seat.
• Weak Flush: Check the water pressure at the inlet. Ensure the Bak-Chek angle stop is fully open. A clogged diaphragm or debris in the valve can also restrict water flow.
• No Flush: Verify that the water supply is on and the angle stop is open. Check for any obstructions in the handle mechanism.

For persistent issues, it is recommended to contact a qualified plumber or Sloan technical support.
