water heater leakin pressure release valve
I noticed today the pressure release valve on my water heater has a very slow drip. How often should that valve be replaced and is now the time. Doesn't seem like a complicated job any precautions ...

Might not be the valve.. Before you go tossing money at it try this procedure.
1: turn off heater.. Wait as long as you can.
2: Shut off water to heater, Either use the bypass system or turn off water to the RV (Both city and on-board pumps).
3: Remove drain, NOTE: I like to pipe the flow out past the side wall of the RV.
CAUTION hot water under pressure
4: Open TPR (the Release valve) to increase outflow.
5: When outflow stops, close TPR and replace Drain plug, IF SURBURAN or other anode using heater inspect anode while you have it out and if in need of a new one, Now is the best time.
6: Restore water flow to heater and let fill.
7 REstart heater
Now see if it still leaks.
Water heater is also an acumulator tank and over time the air cushion is absorbed into the water and vanishes, leading to leakage at the TPR as the water heats, due to overpressure .
