NEPTUNE 2004
The water heater is equipped with a Pressure-
Temperature relief valve. The water heater may discharge
from the Pressure-Temperature relief valve during the
heating cycle, due to thermal expansion of water. The
Pressure-Temperature relief valve is designed to open if the
water temperature in the tank reaches 210° F (98.8° C), or if
internal pressure reaches 150 psi. A small discharge is
normal and is not necessarily a faulty valve. The water
heater has an internal air pocket to reduce the possibility of
dripping or weeping.
Eventually, the expansion of the water will absorb the air
pocket. When this occurs, the air pocket will have to be
replaced utilizing the following procedure.
CAUTION: Ensure the water heater tank is cool
prior to making any check of the valve.
Re-establishing the Air Pocket:
Step 1:
Turn
OFF
the water heater.
Step 2:
Shut
OFF
the incoming water
supply.
Step 3:
Open a hot water faucet closest
to the water heater.
Step 4:
Pull the handle of the relief valve
until the flow of water stops.
Step 5:
Close the relief valve allowing it
to snap shut. Close the hot faucet
and turn
ON
the water supply.
Step 6:
Turn
ON
the water heater.
The air pocket is re-established and the process does not need to be repeated
until the next discharge of water from the Pressure-Temperature valve. If the valve
continues to leak, contact a qualified service center to evaluate the valve and make
any required repairs.
