Kind of depends on the maker of your heater. If an Atwood, then no anode rod is necessary.

If a Suburban, then I would use use one because eventually the inside will corrode due to the water being present, even if only part time. The one that comes with the Suburban should last quite a long time though. Just inspect it when you pull it out to drain the heater. When it gets to looking like a rough piece of thin pencil then replace it.

My water heater has no consumer temperature control or anode, I am sure it was the cheapest model when it was installed 10 years ago.

It is still going strong on both gas and electricity.

I drain it for winter and if is going to be stored for a long time.

Sounds like an Atwood and it being a 2010 vintage it would be a:
GC6A-10E if 6 gal
GC10A-4E if 10 gal

Most current combo versions and NOT the cheapest (could have been a pilot gas version)


Atwood and Suburban both use pre-set t-stats (no agjustments)
*atwood does have a cheap adjustable optional t-stat


Is it time for your medication or mine?

Old biscuit, yes it is a 6 gallon Atwood. It is hotter than the dickens. Fortunately, it is well insulated so we run it for 15 in the morning and we are good all day or until we do dishes.

Yes. For the small price of the anode rod keep it. I have gone as much as 3 years on one anode, very little damage. It only dissolved at the end of the 3rd year.


3 yrs?

Mine came with the trailer when I bought mine in 2010 and is still mostly there. [emoticon]

T-stat controls heat cycles......OPENS at 140*F/Closes for reheat at 110*F
ECO (Energy Cut Off---HIGH temp t-stat) Opens at 180*F/triggers FAULT Light (t-stat recloses at 150*F but FAULT Light has tobe manually reset)

Options are available>

Atwood has a 130*F optional T-stat (Atwood 91470)
Some websites will list it as 120*F but that is incorrect.....no 120*F available discontinued years ago)

Atwood Adjustable 110*F - 150*F T-stat (Atwood 93105)

I've heard that. I've never had one go over 3 years. One lasted me 1 year. This was on the same trailer. Not sure what makes them last longer? On my current MH it came with a new one. I just drained the water tank to get out some nasty campground water and the rod was already coming apart down by the threads. I kept my trailer plugged in at the house so not sure if being plugged in caused them to wear out faster.

If using the same water heater and same water then the difference is either fluctuations in the makeup of the water or in the makeup of the rods.

Aluminum anode rods last longer than magnesium but offer less protection. The water quality is a big factor in anode longevity. If you are using the same water as your home, how often do you change the anode in the house water heater?
