PRESSURE-TEMPERATURE
RELIEF VALVE
On occasion, water may be seen seeping from
the water heater pressure temperature relief
valve. This is no cause for repair or replacement
of the valve.
Water Heater Exterior Service Access
Normally there is an air gap at the top of the
water heater tank, which acts as a pressure buffer.
In time, however, heated water may expand and
fill this air gap, causing a slight increase in water
pressure. This may cause the P-T valve to "weep"
until the air gap is manually replaced.
CAUTION
Hot water can escape from tank causing
injury. Operate this valve only when the
water heater and engine cooling system
are cold.
To Replace the Air Gap:
1. Turn off the Water Heater switch and
incoming water supply (city water and/or
demand pump).
