WH T&P valve drips on electric but not gas
We have a 6 gallon DSI gas & electric WH, new in 2014. On our first trip I noticed that when on electric, but not gas, the temperature & pressure relief valve would drip. So the dealership replaced ...

Could be the water in the heater is heating up just to the point of popping the valve, but not quite, but just a bit allowing it to drip.The electric is getting the water hotter than the gas. If this is happening, not much you can do about the relief valve, it's doing it's job.
If it is just a slight drip, I wouldn't worry about it. Mine drips sometimes, enough to leave a little puddle of water in the bottom of outside cabinet area. But, I've never seen it actually drip. So I figure the heat in the heater is at that point, and the valve is doing it's job. I don't worry about that little puddle of water.
Now, if your valve is dripping fast, like 1 drop a second, or faster, then something is definitely getting too hot. Considering this is your second valve, I'd say there's nothing wrong with the relief valve. It's working as it's suppose to. The problem is elsewhere. (getting too hot).
