Water with a pH of less than 7 is considered to be acidic and potentially damaging causing staining and corrosion, Using a pH correction unit balances the acidity of the water and eliminates the threat of staining and corrosion.

Treatment by means of a pH correction filter involves the use of a neutralising media, generally composed of crushed and processed limestone. This media dissolves into the water as it passes through the filter and the natural alkalinity of the filter media raises the pH.            

The system that is right for you depends on the maximum flow capacity in your home.
See the technicals tab for a technical information table for the pH Correction Unit.
