Installation Instructions
- Turn off all power and shut off gas to the heater before servicing.
- Allow the heater to cool completely and relieve any pressure in the system.
- Unscrew the old relief valve from its port.
- Apply appropriate thread sealant or Teflon tape to the new valve threads.
- Thread the new CHXRLV1930 valve into place and tighten securely by hand or with a wrench (without overtightening).
- Restore power and gas, then run the heater briefly to check for leaks.
Troubleshooting
-
Valve dripping or seeping: Verify the valve is tightened correctly and that thread sealant is properly applied.
-
Valve opening frequently: Investigate underlying system pressure issues such as restricted flow, dirty filter or pump problems.
-
No relief function: Replace immediately—relief valves that do not open properly pose a safety risk.
Maintenance Tip
Inspect the pressure relief valve during annual heater service. Replace immediately if signs of corrosion, leaking, or mechanical sticking are present. Maintaining a functioning relief valve is essential for safe and reliable heater operation.
