Hard Water. “What is hard water?” That is a question we get a lot. The answer is simple. The problems generated by hard water are a bit more complex. It has been said that “Water is the universal solvent”. That means it dissolves just a little bit of everything it touches. When water passes through the deep underground rock deposits, it dissolves and carries with it small amounts of calcium & magnesium along with smaller amounts of other minerals. These minerals dissolved into the water, make the water “hard”. They will later fall out of solution and leave their mark all around your house in the form of “water spots”. These water spots can cause a host of problems from spots on you black car after washing to deposits in your hair making it heavy and stiff… even brittle.
