Anode Rod Wear
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.

I agree that those rods are still good for another year.
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.MFL wrote:

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 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.
Jerry - You may want to switch to an aluminum rod. Keep an eye on it to see if decays more evenly.
magnesium anode link from OP - It's this rod. I'll just plan on buying a new one before camping season.

yes, basic chemistry and electrolysis. I will corrode from the end closest to where it is attached to the tank and progress down towards the far end.fj12ryder wrote:
