So I'm reading an RV magazine and specifically an article about appliance maintenance. And in that article regarding the water heater inspection it mentions if your water heater has an aluminum tank such as Atwood, inspect the plastic plug for signs of leaking. Then it states: Avoid using metal drain plugs such as steel or brass. Galvanic corrosion will occur, which can lead to the threads rusting together. This makes the plug very difficult to remove.

I had a plastic plug on my water heater and the head was rounding off making it difficult to install or remove correctly with a socket. I replaced it with a "sturdy" brass plug and was quite pleased with myself until I read the above. Should I change it back to plastic? Your thoughts please.
