What to do with thatGet your hardness figure

You do not need a test kit to start. Notus City of publishes hardness in its annual water quality report, free to read. That figure comes in milligrams per liter. Divide by about 17 to get the grains per gallon a softener is rated in.

Put it through the sizing calculation and you will know what to accept and what to refuse. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
