Anode Rod for Atwood

That reminds me, I have to change one out in my Suburban tank. Thanks.

As stated above, not needed in an Atwood. In fact the owners manual says not to use one.

Suburban water heaters require an anode rod due to their construction (steel tank). Atwood water heaters are aluminum and do not require an anode rod. They typically have a plastic drain plug that can break when the plastic gets old and brittle. I'd suggest you pick up a spare drain plug the next time you're in an RV parts store and carry it as a spare.

What TJ said. That's all you need.

What TJ and Ozlander said. You do not need an anode in a new Atwood. I remember reading that the old (many years old) Atwoods used a steel tank and needed an anode but that was many, many years ago.

Yes, the purpose of the anode rod is to take the corrosion rather than your tank. They're inexpensive compared to replacing your tank and easy to install and replace.

Do you have one now? If so, do you know when/if it was ever changed?
Not much of a problem to change but for an upgrade not sure i would mess with it.
