The Proof

Why Do San Diego
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 San Diego.

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

Surface water, like rivers and snow melt, absorb contaminants that can be harmful for consumption as well as annoying around the home. Most of these contaminants include naturally occurring bio materials and minerals. This means water quality can worsen seasonally when warming temperatures contribute to algal blooms, or heighten water sensitivity to microorganism growth.

Ground water presents its own treatment challenges and filtration issues, so San Diego residents with primarily ground water service may see different water problems than those using water from San Diego’s surface water sources. Most often, these manifest as hard water problems which cause buildup on faucets and fixtures, and can be hard on appliances and plumbing.

One of the biggest water challenges facing San Diego and greater Southern California is water scarcity. As climate changes continue to intensify droughts, communities can expect to see cities invest in — and use — a greater variety of water resources to supplement unpredictable rivers and aquifers. As this process expands, the need for dependable, effective water filtration will become increasingly important.

At Culligan San Diego, we’re dedicated to providing the highest quality drinking water and whole home water filtration solutions, no matter where you live in the city, or what kind of water you have.
