Water Softener Installation in Lakewood, CA

Lakewood is supplied by Lakewood - City, Water Dept., 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.

Where the water comes fromGround water in Lakewood

A ground water system on this scale is usually pulling from a well field rather than a single bore, and the hardness of what it delivers reflects the aquifer underneath it rather than anything the treatment plant does.

Lakewood - City, Water Dept. serves 20,041 service connections. That is the system's own return to the EPA, as of the second quarter of 2026.

What to do with thatGet your hardness figure

You do not need a test kit to start. Lakewood - City, Water Dept. publishes hardness in its annual water quality report, free to read. It will be given in milligrams per liter. Softeners are sized in grains per gallon, and one grain is about 17 mg/L.

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.
