What to do with thatGet your hardness figure

The figure you need is already published: West Linn, City of issues an annual water quality report, and hardness is one of the lines on it. Whatever it reads in milligrams per liter, divide by seventeen before comparing it with anything a softener is rated at.

From there, the sizing math takes a minute and tells you what capacity actually fits the household. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
