Anode rod or not?
« on: March 04, 2017, 09:11:44 PM »
On my 2006 mallard travel trailer there isn't an anode rod in the water heater.
I also have a popup and it does use a long anode, and it works very well.
The question is; why does the TT does not have one? Do the manufacturers want the heater to corrode and me to buy a new one? Or is it flushing all it takes to keep it clean? If so, why does the popup have one?
Thanks for your answers!

Ann Atwood water heater does not use an anode. The inside of the tank is protected.
A Suburban water heater tank is not protected so it uses the anode.

Thanks for your reply!
I didn't know about that. Doesn't say anything in the heater manual and I was thinking that they just forgot to add an anode rod for protection.

A freind of mine replaced the nylon drain plug with a brass one.  A few months later his Atwood started leaking.  My theory is that the brass set up conditions for electrolysis.  He's an engineer and should have known better.   ::)

Rene is correct. Your TT probably has an Atwood water heater which has no anode. Tank construction doesn't require it.
Your popup probably has a Suburban water heater. Different tank construction, which does include an anode.

On my 2006 mallard travel trailer there isn't an anode rod in the water heater.
I also have a popup and it does use a long anode, and it works very well.
The question is; why does the TT does not have one? Do the manufacturers want the HEATER to corrode and me to buy a new one?

Based on the wording, you're not confusing an electric element for the anode, are ya?     
Make and model # should clue us in.
