Question regarding anode rod

Hi all,
I have a 2001 Rockwood Premiere model # 2302 pop up and I believe it has a Suburban ( no labels or other distinguishing markings ) water heater and after pulling the old rod, which was shot and draining the system and getting ready to winterize, I want to put a new rod in to replace the old worn out one. My issue is, I don't know which one I should purchase as I have no owner manuals ( bought 2nd hand, previous owner misplaced ) The old rod is 8 1/2" long by I an assuming 3/4". I have called a couple of dealers in my area and they say I need a model number in order to get the correct one .. Can anyone provide any assistance in getting the right rod? TIA

No labels on the inside of the outer hatch cover?
It's most likely this one which pretty much fits them all....

That's the magnesium rod which I prefer over aluminum and it's a pretty good price as well....

I advise putting teflon tape on the threads to keep it from seizing in there. Good luck!

Happy Trails!!

All the labels, on the inside of the door and on the unit itself have been wiped clean of print.. black except or a word here and there. Thanks for the quick answer, ordered one.. and will most definitely use teflon on the threads.

Smile follow up anode rod ?

Forestlaker, Once you have found a replacement anode rod, will you be putting it in the WH for the winter or leaving it out until spring? Also, is there an oil of some kind that is safe but still keeps the rust at bay?

Yes, I will be reinstalling the rod before I put her up for the winter. I've used a small wire brush to clean the threads and rinsed them using a mustard bottle with the squirt cap making sure to get any/all rust out of them before attempting to screw in the new rod. I'll only wrap half the threads on the new rod with teflon tape and put a small dab of marine grease on the exposed threads to help lubricate and prevent any future rusting ( I hope ). As this is my first ( bought used, former tenter for many years ) pop up and first anode replacement I've read quite a few threads on the subject. I haven't come across any describing the use of a non toxic oil but imagine using a food safe mineral oil ( from a drug store ) would work

If you cleaned the threads like youíve described, then you put on the Teflon tape on the part that threads in, and put grease on the exposed threads, youíre good to go for reinstalling the anode. You donít need any type of oil.

Only use silicone plumber grease. It is Waterproof and non-hazardous. It is good -40 to 400F.

One more question

So, you are not afraid of a mold issue in the WH. I think it might take mine some time to dry out? Appreciate the tip on the plumbers silicone

My 2 cents. While you are at it you may want to consider getting a rv water heater flush nozzle and give it a good rinsing before you put the new anode in. Get all the gunk and Calcium out, it will add years to your WH.

There is an anode rod with tap available- I've never used one, does anyone have experience with such an item?
