Water softeners act to eliminate the problems caused by water that is high in calcium, magnesium, iron, and manganese. These conditions invariably result in water that is corrosive and which leaves reddish/brown stains on plumbing fixtures, clothes, dishes, and tile. A softener eliminates these problems and provides you with water that is cleaner, clothes that are whiter, dishes that sparkle brighter, soap that lathers better, and plumbing systems that last longer
