TEMPERATURE PRESSURE RELIEF VALVE OR EXPANSION CONTROL VALVE RUNNING
•
Normal Operation
It is normal and desirable the temperature pressure relief valve or
expansion control valve (if fitted) allows a quantity of water to escape
during the heating cycle. This quantity should be equal to
approximately 1/50 of the hot water used, as water expands by this
volume when heated. However, if it discharges more than a bucket full
of water in 24 hours, there may be another problem.
The expansion control valve (if fitted) will discharge water instead of
the temperature pressure relief valve as it has a lower pressure rating.
A benefit is that energy is conserved as the discharged water is cooler.
This valve is installed in the cold water line to the water heater (refer
to the
cold water connection diagram
•
Continuous dribble
Try gently raising the easing lever on the relief valve for a few seconds
"Relief Valves"
(refer to
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 from the temperature pressure relief valve 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 / Centre to arrange for inspection.
HIGHER THAN EXPECTED ELECTRICITY BILLS
Should you at any time, feel your electricity bill is higher than expected, we suggest you check the following
points:
•
Is the relief valve running excessively?
"Temperature Pressure Relief Valve or Expansion
Refer to
Control Valve Running"
Are outlets (especially the showers) using more hot water than
you think?
"Not Enough Hot Water"
Refer to
•
Is there a leaking hot water pipe, dripping hot water tap, etc?
Even a small leak will waste a surprising quantity of hot water
and electricity. Replace faulty tap washers, and have your
plumber rectify any leaking pipe work.
•
Has there been an increase in hot water usage?
An increase in hot water usage will result in an increase in water heater operation.
•
Has your water heating tariff rate been increased by your electricity retailer since your previous bill?
•
The electricity tariff to which your water heater is connected will determine the overall operating cost of
the system.
It is important you are aware of this tariff, i.e. continuous or time controlled supply.
IF YOU HAVE CHECKED ALL THE FOREGOING AND STILL BELIEVE YOU NEED ASSISTANCE, PHONE
