My water heater has 2 magnesium anodes, should I replace both?
Our response
The answer is no and that is why Corro-Protec offers different models adapted to tank sizes.
If your water heater has two anodes, you can replace one of them with our Corro-Protec imposed current anode and leave the other one in place. Even if you install the Corro-Protec anode to eliminate the rotten egg smell in your hot water, you don’t need to remove the second magnesium anode.
