RDWS-PH-MAX Low pH Water Filters
The RDWS-PH-MAX Series low pH water filters are an effective solution to neutralize acidic water, particularly found in well water. Acidic water can cause corrosion of your plumbing and is especially damaging to copper pipes. Copper corrosion manifests itself in causing blue/green stains on bathroom fixtures. Calcite dissolves calcium into the water as water passes through. This adds beneficial minerals to the water and adds to the total alkalinity of the water. Total alkalinity will reduce the risk of corrosion caused by otherwise unstable pH waters. Calcite filters can be added after sediment filters and before our iron removal filters to increase efficiency.

How it works:
The cylinder is installed into the water supply as near to the source as possible so that all the water from that point onward is neutralized. Water passes into the cylinder and permeates through the calcite pH correction media before passing out into the main water line again. The media dissolves into the water until the pH raises to a neutral level and stops dissolving once the pH is raised. 
Calcite is designed to add some calcium to the water that will contribute to water hardness.

This is a self-backwashing system that automatically cleans its filter bed. This is accomplished with the electronic control valve that is mounted on top of the RDWS-PH-MAX tank. This valve is controlled by a timer that on a regular interval, initiates the backwash cycle that cleans the bed of pH correction media and resets it for the next period of filtration. Periodic backwashing will prevent packing, reclassify the bed and maintain high service rates. 

The RDWS-PH-MAX systems are fully delivered with media already in the tanks. New: User friendly no-tools needed to attach control valve to tank - simply screw control valve on tank when ready for installation. This saves time, money, and headaches for the self installer, your local plumber, or dealer!


Easy maintenance: The RDWS-PH-MAX-10 and 13 Series use media tanks with Dome holes designed to make adding your pH correction media easier without removing the control valve. Calcite slowly dissolves in the water to correct the ph of your water. You will need to add more pH correction media approximately once a year. Usually 1-2 bags depending on water usage.
