TEMPERATURE AND 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 and Pressure Relief
Valve” on page 9). 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.
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 your nearest Rheem Service Department or 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 21) it may discharge a small quantity of water instead of the Temperature
and Pressure Relief valve on the water heater. The benefit is that energy is
conserved as the discharged water is cooler.
