Hard Water Deposits

Hard Water SpotsWater spots on dishes, scaling on faucets and fixtures, buildup in pipes, dry skin, shortened lifespan of appliances, and reduced effectiveness of soaps and detergents are all signs of hard water. Did you know that over 85% of all homes in the U.S. have hard water? This common issue is a result of high concentrations of minerals in the water supply (typically magnesium and calcium). Having hard water is harmless to your health – in fact, calcium and magnesium are both essential to the human diet. However, hard water can wreak havoc on your water heater and other water-using appliances, significantly reducing their lifespans. A home water softener can solve your hard water problems.
