Water Softener Installation in West Greenwich, RI
West Greenwich is supplied by Kent County Water Authority, which draws surface 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
Kent County Water Authority supplies West Greenwich from a surface source. Surface water has had far less contact with rock, so it is more often soft enough to leave alone. Hardness is published annually by the supplier, and that one figure is what a softener decision should rest on.

What to do with thatGet your hardness figure
Ask Kent County Water Authority for its water quality report, or find it online — hardness is on it, and it is the number the rest of this turns on. Reports use milligrams per liter, installers use grains per gallon, and mixing the two up is how people end up oversized.
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.
