TEMPERATURE PRESSURE RELIEF VALVE RUNNING
Normal Operation
It is normal and desirable that 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 11). 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 water heater is cold - then stops until
water reheats
The water heater
must
be switched off at the 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 the
cold water connection diagram
on page 27) 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.
