What to do with thatGet your hardness figure

Davis Junction reports its hardness every year. Reading that one line takes a minute and it is the step most households skip. That figure comes in milligrams per liter. Divide by about 17 to get the grains per gallon a softener is rated in.

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.
