Water quality in Des Moines: Des Moines has hard water — a water softener is strongly recommended. Scale buildup shortens the lifespan of water heaters, dishwashers, and washing machines while causing chronic dry skin and spotted fixtures.
Hard water above 7 GPG causes scale buildup inside pipes, water heaters, dishwashers, and washing machines — shortening their lifespan and increasing energy bills.
