What it does for your home
- Removes acidic / low-ph water from your water
- Stops blue-green staining and pinhole pipe leaks
- Protects copper pipe, solder and fixtures
- Brings pH into a safe, non-corrosive range
- Self-backwashing calcite bed
How it works
Calcite dissolves slowly to raise low, acidic pH toward neutral, so water stops eating copper pipe and fixtures. It is self-limiting and is topped up as it is used.
Media benefits
Calcite pH-neutralizing media
- Raises acidic, low pH toward neutral
- Stops blue-green stains and pinhole leaks in copper pipe
- Self-limiting: it will not over-correct the pH
- Easy upkeep: simply top it up as it is used

Pentek Acidic / Low-pH Water System
A complete Pentek system — control head valve, tank and the right media — engineered to solve acidic / low-ph water for good.
The Pentek system that solves it
This is a full Pentek system built on three parts that work together: a Pentair Autotrol Logix backwashing control valve on top of a backwashing calcite tank, filled with the media matched to your water. The valve backwashes the bed on schedule to keep flow strong and the media working — no cartridges to change. One consistent Pentek platform means parts and service stay simple for the life of the system — fully serviceable, never a sealed throwaway unit.
