Water quality in San Antonio: San Antonio has very 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. In San Antonio, a properly sized water softener installed by a licensed plumber is one of the most cost-effective home improvements for long-term savings.
