Whats the difference between naturally soft water and the water from my water softener?
A. There’s a great deal of difference! Naturally soft water is generally acidic and contains very few dissolved minerals. This tends to make the water quite corrosive to pipes and plumbing. The softened water from your home appliance is more like the raw water from which it is made. It is usually alkaline rather than acidic, and contains moderate amounts of dissolved minerals. Thus softening a hard water in the home does not significantly affect corrosion.
