A urinal flush valve may keep running due to several common issues: 1. **Worn or Damaged Diaphragm:** The diaphragm inside the flush valve can wear out or become damaged over time, preventing it from sealing properly. This can cause water to continuously flow into the urinal. 2. **Debris or Sediment Buildup:** Debris or sediment from the water supply can accumulate in the valve, obstructing the proper sealing of the diaphragm or other components, leading to continuous water flow. 3. **Faulty or Misaligned Handle Assembly:** If the handle assembly is not functioning correctly or is misaligned, it may not return to its original position after flushing, causing the valve to remain open. 4. **Improperly Set or Damaged Stop Valve:** The stop valve controls the water flow to the flush valve. If it is not set correctly or is damaged, it can cause excessive water flow, making the valve run continuously. 5. **Pressure Fluctuations:** Variations in water pressure can affect the operation of the flush valve. If the pressure is too high, it may prevent the valve from closing completely. 6. **Worn or Faulty Gasket or Seal:** Gaskets and seals within the flush valve can degrade over time, leading to leaks that cause the valve to run continuously. 7. **Incorrect Installation or Adjustment:** If the flush valve is not installed or adjusted correctly, it may not function as intended, leading to continuous running. 8. **Valve Body Damage:** Physical damage to the valve body itself can prevent proper operation, causing the valve to remain open. Addressing these issues typically involves cleaning, repairing, or replacing the affected components to restore proper function.
