What to do with thatGet your hardness figure

Before anyone visits, pull the hardness figure out of the annual report Manassas, City of publishes. It settles most of the question on its own. Utilities publish milligrams per liter; the trade talks in grains per gallon. Seventeen of the first make one of the second.

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.
