Source and coverage
Scottsdale Water water quality informationThis is municipal water information, not a test of your home. Check the utility on your water bill, particularly near city boundaries or if you use a private well.
How we verify sources and handle estimatesChoosing a softener for your home
Start with a hardness test on the water entering the softener. Next, estimate the household water use that actually passes through it. Outdoor irrigation is usually a separate demand and should not automatically be included.
A softener needs enough usable exchange capacity between regenerations and enough service flow for fixtures used at the same time. The advertised grain capacity is not necessarily the capacity at an efficient salt setting. Compare the manufacturer's capacity and salt-dose table, ongoing salt use, installation requirements and warranty.
