What Is Hard Water?
As rainwater passes through the earth into lakes, streams and ground water, it picks up certain “hardness” minerals such as calcium and magnesium – minerals that will clog pipes, and may damage your appliances. Iron can be particularly troublesome, leaving rust stains.
The ion-exchange process in a water softener removes hardness, commonly known as “softening” the water. This reduces the maintenance associated with cleaning or replacing processing pipes and appliances that are clogged with hardness deposits.
