Water Softener Installation in Loma Linda, CA
Loma Linda is supplied by Loma Linda, City of, which draws ground water. That one fact does more to predict whether a softener is worth it here than anything a salesperson will ask you on the phone.
The short version
Loma Linda, City of supplies Loma Linda from a ground source. Water out of the ground has picked up whatever the rock holds, and calcium and magnesium are what hardness means. Hardness is published annually by the supplier, and that one figure is what a softener decision should rest on.

What to do with thatGet your hardness figure
Before anyone visits, pull the hardness figure out of the annual report Loma Linda, City of publishes. It settles most of the question on its own. It will be given in milligrams per liter. Softeners are sized in grains per gallon, and one grain is about 17 mg/L.
With the figure in hand, sizing is one multiplication — water per person, times hardness, times people. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
