What to do with thatGet your hardness figure

Start with the published figure. Wilsonville, City of reports hardness annually, and that number is what any honest quote gets built on. Utilities publish milligrams per liter; the trade talks in grains per gallon. Seventeen of the first make one of the second.

Work out your grains per day before anyone quotes you. Oversizing is the common and expensive mistake. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
