Anode Rod Wear

[Mr__C]

What would cause severe wear to the rod at the connection end? Almost no wear on the rest of the rod. I use teflon tape on the threads. Two brand new rods, two years in a row.

lots of life left for those two rods

Yep, if thats from one season of use it looks like they would be good for another 8-10 years, but if folks feel better wasting money every year for a new rod more power to them. Those rods will perform just as well as a new one.

I would change them at about 50% use. there cheep insurance.

its a little deciving how they wear out, mine look simular to his after 1 season. after the next they are about 50% gone. it also depends where I go camping nd what the water is like there.

Changing rods sure beats changing large heaters and tanks every 4-5 years! Craig

^^^ I agree with everybody. I've changed a bunch of rods in commercial heater/tanks and sometimes they do that. I always change them, as long as I have the water drained down. Craig

That's what the rods from my heater look like after 1 year.

They are not expensive so I just put in a new one in the spring.

I use the Suburban rods, they seem to hold up better.

Those rods look good, if each had a years use. You can easily get another year of use out of either of those. Looks like 80% or more left, and should be able to use down to 25-50% with still good protection.

Your money, you decide, but changing to aluminum not necessary.

I agree, I switched to magnesium because I was getting a lot of the slimy aluminum compound in the bottom of the tank. Changing to magnesium took care of that issue.

I tried changing to an aluminum rod once. After two years it still looked new. Didn’t seem to be doing its job so I switched back to magnesium.

If you have very hard corrosive water that quickly eats magnesium anode rods, then a switch to aluminum is reasonable. If it takes years to do in a magnesium rod, then the magnesium rod is the best choice and provides the best protection.

Ours always erodes quickest nearest the threads, which I believe is the reason: closest connection. But just a guess.

Mine too, and same guess.

Same with mine. I continue to use it as it will still sacrifice for a time.

Thanks for the advice. I'll just reuse the better of the two.

You may want to switch to an aluminum rod. Keep an eye on it to see if decays more evenly.
