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 8). 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 gas control must be turned off using the knob on top of the gas control thermostat (refer to “Close Down Procedure” on page 27). Phone your nearest Rheem Service Department or Accredited Service Agent to arrange for inspection.
EXPANSION CONTROL VALVE RUNNING
If an expansion control valve is fitted in the cold water line to the water heater (refer to page 20) 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.
