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. 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 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 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. Phone your nearest Rheem Australia office or accredited service agent to arrange for inspection.
