If your water heater starts 'leaking' from the pressure relief valve you try two things to stop it. A. Very carefully lift the manual lever on the valve and let it sit back. This may reseat the gasket (USE CAUTION - THE WATER IS HOT!!).
B. You may also need to restore the air gap in the water heater.
To do this the unit MUST be off and cool.
1. Turn off the water pump or city water supply and open hot faucet in the RV.
2. Next open the drain on the water heater and let all the water drain out.
3. Close the faucet and with the pressure relief valve OPEN, turn on the water pump. Let the water heater fill until water just starts coming out of the valve. 4. Close the valve and restart the water heater.
