Water heater pressure release valve

2002 Montana. How easy/difficult is it to replace a pressure release valve on the water heater? Mine has a slow drip that probably will just get worse as time goes on. THANKS

Are you sure you have an air trap at the top of the tank. If there is no air trapped at the top then the expanding water will cause the pressure relief to drip and appear to be faulty.

To restore an air trap at the top of the tank:
1. Turn off water pressure/source.
2. Open a hot water tap.
3. Open the pressure relief valve and allow water to drain to that level.
4. Resume normal operation.
