Winterization hitch
I went to remove the anode plug on my 19RD with my trusty 1 1/16" socket I used on my old trailer - and the anode was a a different size than I expected. Not as big as the socket I had, but bigger than the biggest of the rest in the set. Does anyone know the size? It's an Atwood 6 gallon.
Also, are the threads stainless in the water heater where the anode enters? I was always fighting rust on the threads of my old trailer.
Thanks
Dave

I always broke that item loose with an adjustable wrench.
Then pliers until fingers could spin it.
Then the back-and forth through the corrosion.
Give the tank a good flush from the hose. Leave open until spring.

Do the Atwood heaters have an anode? I thought it was just the Suburbans...?

As far as I understand, only the Suburbans have anodes.

Ah. that might explain why I could not find an anode reference in the Atwood manual. Thanks for the tip.

You still should pull the plug and ensure the water heater is drained.

Atwood does not use an anode rod because the tank is aluminum and not needed.

Mine has a plastic plug that took a 15/16" socket.

And the best thing to do is to remove the plug, discard it, and replace it with a brass valve.
Leaks from a cracked plug or cross threading can then be avoided.

With my Atwood aluminum tank(s) I've always used the plastic plugs without incident (no potential for dissimilar metal issues) ...., I also like how the inside recessed 'cup' of the plastic plug catches loose calcium.
An adjustable crescent wrench works best for removing/replacing my plug.

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.

+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.

Yeah, because brass never cross threads and valves never leak..
