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 15).
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 11).
