Water heater anode rod

[drsteve]

My two year old Coachmen has a Suburban water heater. How long can I expect the anode rod to last? This is what the current rod looks like:



When I replace it, should I get a magnesium rod, or an aluminum one?

Thanks in advance!

Magnesium is the recommended choice, and should last for a year, or more, depending on water quality. If really bad water, and going through the mag rods quickly, then the aluminum rod is a better choice, and will last longer. The aluminum rod, does not give as much protection as the magnesium one.

If your current rod is mag, and looks that good after 2 years, you are doing very well, and likely using good water.

Looks fine to me.

Another year maybe.

Replace them when you can see the core rod. Click here for an example.
