Signs your flush valve needs replacing
- Water runs continuously into the urinal
- Weak or incomplete flushing
- The handle sticks or feels loose
- Visible leaks at the valve or connections
Replacement steps
- Turn off the water at the control stop.
- Flush to release pressure, then disconnect the old valve from the supply and the flush tube.
- Clean the connections and check the vacuum breaker and flush tube.
- Install the new valve, tightening the couplings by hand and then lightly with a smooth-jaw wrench to protect the chrome.
- Open the control stop slowly and test the flush. Adjust the stop to set the flow.
Maintenance tips for facilities
- Inspect restroom fixtures monthly in high-traffic buildings.
- Keep spare parts on hand to avoid out-of-order signs.
- Clean chrome with mild cleaners to preserve the finish.
Maintenance Depot supplies facility managers with valves, flush parts and drains, so ask about stocking spares.
