Kern County Bakersfield Plumber

Bakersfield is the one place on our list where we don't lead with hard water. Cal Water's numbers here are soft to moderate, so the work is about permits, old lines and the plumbing on your side of the meter.

Plumbing In Bakersfield

Cal Water serves Bakersfield from three sources: local wells, Kern River water filtered through membranes, and water bought from the Kern County Water Agency. Its wells average 105 mg/L of hardness, moderately hard, and its river water about 49, which is soft. Next to the Santa Clarita Valley, that's easy on a water heater.

Cal Water's Bakersfield wells run from 52 to 380 mg/L, so hardness varies a lot by address and by source, and a softener isn't the automatic answer. What does come up: the City of Bakersfield requires a permit to install a water heater, and plumbing on the house side of the meter is the owner's to repair.

  1. A Permit For Every Water Heater

    The City of Bakersfield says a permit fee and special permit are required for several kinds of residential work, and lists installing a hot water heater among them.

  2. Where Cal Water Stops

    Cal Water says it's responsible for repairs within its distribution system, and property owners are responsible for repairs to plumbing on their side of the water meter.

  3. Three Kinds Of Water In One System

    Cal Water blends groundwater from its Bakersfield wells, Kern River surface water treated by membrane filtration, and treated water from the Kern County Water Agency.

Easier Water Than Most Of SoCal

Cal Water's own scale calls water soft under 75 ppm and moderately hard from 75 to 150. Its Bakersfield wells average 105 and its Kern River water 49. That puts most Bakersfield taps between soft and moderate, a long way from the 20-plus grains of the Santa Clarita Valley's groundwater.
