REGULAR CARE
TEMPERATURE PRESSURE RELIEF VALVE This valve is near the top of the water heater and is essential for its safe operation. It is possible for the valve to release a little water through the drain
line during each heating period. This occurs as the water is heated and expands by approximately 1/50 of its volume.
Continuous leakage of water from the valve and its drain line may indicate a problem with the water heater (refer to “Temperature Pressure Relief Valve Running” on page 12).
WARNING: Never block the outlet of this valve or its drain line for any reason.
Operate the easing lever on the temperature pressure relief valve once every six months. It is very important you raise and lower the lever gently.
DANGER: Failure to do this may result in the water heater cylinder failing.
If water does not flow freely from the drain line when the lever is lifted, then the water heater should be checked by the Rheem Service Department or their Accredited Service Agent.

The temperature pressure relief valve should be checked for performance or replaced at intervals not exceeding 5 years, or more frequently in areas where there is a high incidence of water deposits (refer to “Water Supplies” on page 38).
