Water Softener Installation in Franklin, NH

Franklin is supplied by Franklin Water Works, which draws ground water. That one fact does more to predict whether a softener is worth it here than anything a salesperson will ask you on the phone.

Where the water comes fromGround water in Franklin

Water drawn from below ground has had time to dissolve whatever the rock will give it. Calcium and magnesium are the two that matter here, because together they are what the word hardness means.

Franklin Water Works serves 2,500 service connections. The system reports that figure to the EPA itself; this is the 2026 Q2 data.

What to do with thatGet your hardness figure

Franklin Water Works reports its hardness every year. Reading that one line takes a minute and it is the step most households skip. It will be given in milligrams per liter. Softeners are sized in grains per gallon, and one grain is about 17 mg/L.

Size it yourself first. A bigger unit is not a safer one; EPA is explicit that oversizing wastes water. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
