Hard water is usually caused by dissolved calcium, magnesium, and iron. Most homes, regardless of whether their water comes from a municipality or a well, suffer from hard water. Unfortunately, most homeowners are unaware of the costly consequences of hard water.
Some of the telltale signs of hard water are dry skin, dry hair, bathtub rings, residue left on glass or silverware, water-using appliances that fail earlier than expected or do not perform as expected. The expenses caused by hard water are usually not realized until it is too late – a failed washing machine or dishwater, etc.
