Washington County Water Quality: Hard Water
Water sampled across Washington County averages 156 mg/L of calcium-magnesium hardness — classified as hard water. For water heater work specifically, this matters more than for any other fixture: calcium and magnesium precipitate out as the water is heated, forming scale on the tank bottom and heating elements. At 156 mg/L, sediment buildup can cut a water heater's efficiency by 10–25% over a few years and shorten its lifespan. Annual tank flushing is essential here, and a tankless unit should always have a softener or scale-inhibitor upstream — scale in a tankless heat exchanger is the #1 cause of premature failure.
