My water heater has 2 magnesium anodes, should I replace both?
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.
What about an aluminum rod? My water heater has two aluminum rods, can I leave one in and install the powered rod in the other spot?
Yes, the Corro-Protec can be installed with a magnesium, aluminium or zinc anode rod without any problem.
Why is this the case? Don’t the bacteria still interact with the magnesium? Is this also the case if you have a water softener and two anodes?
Hello Thor,
If the smell came from the reaction between the magnesium rod and your water, our Corro-Protec anode will create a protection around the second magnesium anode rod that will stop this reaction.
If the smell came from the bacteria, our Corro-Protec create an environment where the bacteria is not able to survive. Having a magnesium rod or not won’t make any difference.
Hope this helps,
Vincent
