The Proof

Why Do El Cajon
Homeowners LOVE Us?

We have used Culligan San Diego for over 10 years. We rented a softener for 4 years and then purchased a system when we bought our home. We have always had great service! They are friendly and helpful on the phone and quickly send a repair guy when needed (and we’ve only needed a repairman 1 time in 6.5 years of owning our system).

Product quality is great. Taste is wonderful. No more buying water at the store. No more refilling jugs. No more running tap water through filter devices. I am particularly impressed by the technicians who make the installation quick, safe, and invisible. And when I moved, they were there to move my equipment at no charge.

A great company. The communication is on point and prompt. Everything has been so smooth. They send reminders (really helps me) and they do what they say. My favorite water delivery company.

The Best Water Softeners and Water Filters in El Cajon.

With this combination of water resources, El Cajon water quality often faces our share of water filtration and treatment issues:

Helix Water District is committed to providing you with safe and reliable water. Our water is a blend of water purchased from the San Diego County Water Authority and local surface water.

SDCWA’s water sources are a combination of imported water from Northern California via the State Water Project and the Colorado River, along with local supplies including saltwater desalination. Over the past 30 years, imported water has accounted for 86 percent of our water supply, on average, due to limited local precipitation. The remainder of our water supply comes from local water runoff collected in Lake Cuyamaca, El Capitan Reservoir and Lake Jennings.

Residents of El Cajon may notice problems with hard water, as their average hardness is 166 PPM and 9.7 grains per gallon.

Whether you’re dealing with a stale, chlorinated taste or odor, or looking for ways to increase the efficiency of your home, Culligan of San Diego has a water filtering solution designed for the type of water problems El Cajon deals with most. Learn more about our filtering solutions for tap water, and find the resources you need to address issues with your drinking water, today.
