What to do with thatGet your hardness figure

You do not need a test kit to start. Parma City of publishes hardness in its annual water quality report, free to read. It arrives as mg/L. Equipment is rated in grains per gallon, roughly a seventeenth of the number.

Next, the calculation — people, gallons, grains. It is the difference between a checkable quote and a trusted one. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
