My Atwood Plug (no Anode) was Inch and a half. I work in a shop that repairs Prevost coach buses so I had a socket large enough.

An adjustable crescent wrench works best for removing/replacing my plug.

+1 Never had a problem with my plastic one, and I'm still using the original plug after 3 years. I remove it and drain the water heater every time I store the unit. It's SUPER easy, and I use a 15/16 socket. That being said, I have a 2-pack of spare plugs in my tool box.

Leaks from a cracked plug or cross threading can then be avoided.
Yeah, because brass never cross threads and valves never leak..
