The reality is in North Carolina we have many locations with varying degree of hard water. It can have all kinds of affects on us as humans as well as our home piping and water delivery and heating systems.
Hard water is caused by dissolved minerals calcium and magnesium and is measured as grains per gallon (gpg). Since we live above and around rocks which contain these elements, it is a natural part of life here.
North Carolina typically in the triad area, can have a range of Moderate hardness from 3.6 to 7.0 grams per gallon.
The good news is, Water Purification Consultants has been for years addressing this problem since 1990.
