Is a softener actually necessary in Maple Grove?

Maple Grove's own water quality report puts hardness at 19 to 22 grains per gallon, roughly 370 ppm, and the report states that most homes here install a private softener. Anything above about 7 grains is considered hard. This is three times that.

That is not a sales pitch, it is the city's published number. The same water plant serves Osseo, part of Dayton and Corcoran, so the hardness story is identical in those cities.

What does hard water actually cost you?

Scale on water heater elements and tank bottoms, which means the unit burns more energy and dies younger. Crusted aerators and shower heads. Spotted glassware. More soap and detergent to get the same result. Shortened life on dishwashers and washing machines.

None of those show up as a single bill, which is exactly why people put off the softener for a decade.

What drives the installed price?

Where the water service enters the house and how much plumbing has to be built to loop the softener in. A house that was plumbed with a softener loop is a straightforward install. A finished basement with the service entering behind drywall is not.

After that: grain capacity sized to your household and your hardness, metered versus timer regeneration, whether a drain and an outlet are already nearby, and whether you are also addressing iron.
