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 19).
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.
Warning: Failure to do this may result in the water
heater cylinder failing.
Warning: Exercise care to avoid any splashing of
water, as water discharged from the drain line will be hot.
Stand clear of the drain line‟s point of discharge when
operating the valve‟s lever.
If water does not flow freely from the drain line when the
lever is lifted, then the water heater must be checked.
Phone Rheem Service or their nearest Accredited
Service Agent to arrange for an inspection.
The temperature pressure relief valve should be 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 14).
