Water heater plug
2021 Four Winds. Went to change out the plastic plug in my water heater and noticed the original appears to be larger than the brass 1/2 one I was going to put in. The original takes a 7/8 wrench, seems large to me. Am I jumping to conclusions?

Are the threads the same? Wrench size may not matter if the threads are the same.

I haven't taken the old one out. I am a bit gun shy to be honest, the plastic plug on my old 2008 RV was leaking so put in a new plastic plug. First trip out the new plug sprang a pin hole leak, had a devil of a time.

There is a very good reason NOT to use a brass plug - galvanic corrosion. Aluminum is highly reactive metal especially in the presence of warm mineralized water. Adding any copper item in contact with aluminum will cause corrosion, so it best to stick with plastic unless you want to replace the aluminum tank in a couple years.
For the chemist around copper has an electric potential of +0.34 volts and aluminum of -1.67 volts. A nice way to make a 2 volt wet cell.

Been running plastic plugs on this and the last rig and never had an issue. I do carry a spare and change them about every two or three years depending on visible wear.

1ST, The plugs are not plastic. They are nylon. The tank is an ALM Atwater. They use two different sizes. 7/8 and 15/16. Do not put a brass plug in an ALM tank. The threads are 1/2". Amazon is your friend.

I did search "my friend" Amazon and I did not find one that mentions the plugs are nylon. They mostly mention 'white plastic', some say PVC and then some do not state what material they are made of.

It seems you are correct but I did read it someplace.
