TEMPERATURE PRESSURE RELIEF VALVE RUNNING
Normal Operation
It is normal and desirable this valve allows a small quantity of water
to escape during the heating cycle. However, if it discharges more
than a bucket full of water in 24 hours, there may be another
problem.
Continuous dribble
Try gently raising the easing lever on the relief valve for a few
seconds (refer to “Temperature Pressure Relief Valve” on page 10).
This may dislodge a small particle of foreign matter and clear the
fault. Release the lever gently.
Steady flows for long period (often at night)
This may indicate the mains water pressure sometimes rises above
the designed pressure of the water heater. Ask your installing
plumber to fit a pressure limiting valve.
Warning: Never replace the relief valve with one of a higher
pressure rating.
Heavy flows of hot water until the water heater is cold - then stops until water reheats
The water heater must be switched off at the isolating switch or switchboard. Phone Rheem Service or
their nearest Accredited Service Agent to arrange for an inspection.
EXPANSION CONTROL VALVE RUNNING
If an expansion control valve is fitted in the cold water line to the water
heater (refer to page 32) it may discharge a small quantity of water
instead of the temperature pressure relief valve on the water heater. The
benefit is that energy is conserved as the discharged water is cooler.
NO WATER FROM THE HOT TAP
No flow of water from the hot tap may indicate a restriction in or failure
of the cold water supply to the water heater. Check for water flow at
other taps and that the cold water isolation valve (refer to page 32) is
fully open.
COLLECTOR GLASS
The Rheem warranty DOES NOT cover breakage of solar collector glass. Check your household insurance
policy covers collector glass breakage.
Warning: No attempt should be made to remove or replace broken collector glass.
The collector glass is not offered as a replacement part. Should a solar collector require replacement, contact
Rheem Service or their nearest Accredited Service Agent.
