Households in Chino Hills are served by Chino Hills, City of, drawing surface water. Surface water has had far less contact with rock, so it is more often soft enough to leave alone. Read the hardness line in the annual report before letting anybody specify a softener for the house.

What to do with thatGet your hardness figure
Chino Hills, City of reports its hardness every year. Reading that one line takes a minute and it is the step most households skip. Utilities publish milligrams per liter; the trade talks in grains per gallon. Seventeen of the first make one of the second.
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.
