Pressure & temperature relief valve
The temperature and pressure relief valve is designed to open if the temperature of the water
within the heater reaches 120° F, or if the water pressure in the heater reaches 150 pounds.
When this pressure is reached, the pressure relief valve will open and water will drip from
the valve.
This “weeping” or dripping will continue until the pressure is reduced to below 150 pounds,
and the valve closes. This condition is normal and does not indicate a defective relief valve.
One way to reduce the frequency of this occurrence is to maintain an air pocket at the top
of the water heater tank. This air pocket will form in the tank by design; however, it will be
reduced over time by the everyday use of your water heater. To replenish this air pocket:
1. Turn off the water heater.
2. Turn off the cold water supply line.
3. Open a faucet in the recreation vehicle.

valve until it stops.
5. Release the handle on the P&T valve - it should snap closed.

Periodically, inspect the water heater vent for soot. Soot is a sign of incomplete combustion
and must be corrected before operating the water heater. This is your visual warning that the
water heater is operating in an unsafe manner.
