Avoid the headaches associated with acidic water with a simple pH neutralizer solution. Increase your water’s alkalinity by filtering it through calcium carbonate media. Install a Pentair pH Neutralizer Water Filter to raise the pH of your acidic water back to optimal levels.

How it works

Acid Neutralization

Occurs when water passes through the media tank that is filled with calcium carbonate media, neutralizing the pH. It reduces the metallic taste from the water, delivering fresh water to the home. The media should be cleaned and reactivated on a regular basis through engaging the backwash cycle in order to keep the mineral bed clean from contamination.


The system will periodically the system will go through a backwashing cycle where water is flushed through the system and up through the media, then discharged to the drain. Backwashing lengthens the life of the media and maintains the performance of the filter.


Backwashing cycles are controlled by the electronic meter on the top of the system’s tank. The backwash cycle can be set to a specified number of days or as the electronic head recognizes that a certain amount of water has been used.
