PERIODIC MAINTENANCE If after manually operating the valve, it fails to completely reset and ANODE ROD INSPECTION continues to release water, immediately close the cold water inlet to the water heater, follow the draining instructions, and replace the temperature-pressure relief valve with a new one. If the temperature-pressure relief valve on the appliance weeps or discharges periodically, this may be due to thermal expansion. You may have a check valve installed in the water line or a water m
