Very Hard WaterNewer Homes

Hard water runs through most Phoenix plumbing calls. Scale shortens water heater life and clogs tankless heat exchangers and aerators, and slab homes put supply lines where leaks are hard to see.

What Phoenix homeowners call plumbers about

  • Water Heater Repair

    At 10 to 17.6 grains per gallon, sediment builds fast in tank heaters. Rumbling, lost hot water and leaks follow.

  • Water Softener Installation

    Many Phoenix households soften to protect water heaters, fixtures and appliances from scale.

  • Leak Detection

    Supply lines under slab foundations hide leaks until the water bill or a warm floor gives them away.

Phoenix's very hard water and your plumbing

Phoenix water comes mostly from the Salt, Verde and Colorado rivers, with about 2% from roughly 20 city wells. Hardness in the city's 2025 report ranged from 172 to 302 ppm (10 to 17.6 grains per gallon), and the city notes hardness can cause scaling in pipes, water heaters and fixtures. [1]
