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 16).

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, or under certain circumstances,

exploding.

If water does not flow freely from the

drain line when the lever is lifted, then

the water heater should be checked by

Rheem Service or their nearest

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 11).
