Can't help, but just wonder what a neutralizer is.

A neutralizer is a device that goes in the water system. Sort of like
a softener. But is makes the water more neutral (in terms of acid).
Neutral is a pH of 7. Acid has pH lower than 7 and alkaline has pH
above 7.

In my case the water coming out of the ground has pH of 5 (acid). And
the neutralizer (when it was working) bring the pH back to 7 so it
doesn't corrode the pipes and such.

Hope the explanation is clear.
