Water Softener Installation in Frankfort, IL
Frankfort is supplied by Frankfort, 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.
The short version
Frankfort supplies Frankfort from a ground source. Water out of the ground has picked up whatever the rock holds, and calcium and magnesium are what hardness means. Hardness is published annually by the supplier, and that one figure is what a softener decision should rest on.

Where the water comes fromGround water in Frankfort
A ground water system on this scale is usually pulling from a well field rather than a single bore, and the hardness of what it delivers reflects the aquifer underneath it rather than anything the treatment plant does.
Frankfort serves 10,823 service connections and is one of 2 community systems in the town. The system reports that figure to the EPA itself; this is the 2026 Q2 data.

What to do with thatGet your hardness figure
Start with the published figure. Frankfort reports hardness annually, and that number is what any honest quote gets built on. That figure comes in milligrams per liter. Divide by about 17 to get the grains per gallon a softener is rated in.
Then run the arithmetic: it tells you the capacity you need rather than the capacity you are offered. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
