Hard water is the most common problem found in the average home.
S oft water greatly reduces the scaling of pipes, faucets, and bath fixtures, and reduces spotting of glasses, dishes and flatware. For many uses, it would not matter. For instance, to put out fires, water your lawn, wash the mud off the streets or float your boat, water would have to be pretty hard to cause a problem. When hard water is heated, the hardness minerals are re-crystallized to form hardness scale. This scale can plug your pipes and hot water heater, causing premature failure, necessitating costly replacement.
