WATER LEAKAGE IS SUSPECTED
1. Check to see if the heater drain valve is tightly closed.
2. The apparent leakage may be condensation which forms on
cool surfaces of the heater and piping.
3. If the outlet of the relief valve is leaking it may represent:
• Excessive water pressure.
• Excessive water temperature.
• Faulty relief valve.
Excessive water pressure is the most common cause of relief
valve leakage. It is often caused by a “closed system”. A check
valve in the inlet system will not permit the expanded hot water
volume to equalize pressure with the main. A relief valve must
release this water or the water heater or plumbing system will be
damaged.
Damage to the water heater caused by a closed system is not
covered by the limited warranty. The only solution is to install a
thermal expansion tank between the check valve and the cold
water inlet to the heater.
IF YOU CANNOT IDENTIFY OR CORRECT
THE SOURCE OF THE MALFUNCTION
1. Place the water heater electrical switch in the OFF position.
2. Close the cold water inlet valve to the heater.
3. Contact your dealer.
