What to do with thatGet your hardness figure

Gresham, City of reports its hardness every year. Reading that one line takes a minute and it is the step most households skip. 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.
