Residen al Hybrid Electric Heat Pump Water Heater Use and Care Guide
• Damage caused by corrosive water
conditions, mineral deposits, or
other problems can only be deter-
mined when a qualified person
removes and inspects the valve and
its components.
• Note that a dripping T&P Relief
Valve is usually caused by the
home’s water pressure being
too high or the lack of a Thermal
Expansion Tank. If your T&P Relief
Valve drips refer to “Drips from
T&P Relief Valve Discharge Pipe” on
page 25.
