Scottsdale's hard water and your water heater

Scottsdale's water is hard, and scale builds up in tanks, tankless units and fixtures. The city calls it a scale and taste issue, not a health one. A plumber can tell you if scale is behind a failing heater.

Scottsdale hard water and meter questions

Questions Scottsdale homeowners ask before they get matched.

Is the water harder in south or north Scottsdale?

The 2025 report's ranges overlap: about 13 to 15 grains per gallon south of Indian School Road, 13 to 17 farther north. Check the latest report before you set a softener.

Does the city soften Scottsdale's water?

No. The city says extra treatment for hardness wouldn't be cost effective. Softening is up to you; a plumber can explain what a softener means for your heater.

How do I check for a leak with my water meter?

Turn off every tap and appliance, then watch the meter. Scottsdale says that if it moves while no water is in use, something on the property is likely leaking. Then get matched.
