What to do with thatGet your hardness figure

Mosier, City of 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.

With the figure in hand, sizing is one multiplication — water per person, times hardness, times people. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
