Family Owned Business for Four Decades

Over 40 years ago, founder and president of De Anza Water Conditioning, John Schafer entered the water treatment business with a California State Contractor’s license combined with a wide and deep understanding of problem water. To compete in this industry, John knew that he needed to provide customers unique and special solutions. He chose to build his business on the strength of Kinetico© Water Systems, supported by a highly specialized technical team and supportive, knowledgeable office staff. Our goal is to satisfy the need of each customer, providing a customized solution for each water problem.

To become a customer of De Anza Water Conditioning is to become a member of our family. We invite you to join our family of more than 20,000 satisfied customers, from San Francisco to Monterey, including residences, apartment complexes, car washes, manufacturers, fitness centers, golf and country clubs, hospitals, hotels and motels, industrial boilers, laboratories, nursing homes, restaurants, universities, custom and town homes, and wineries.

Superior Products: Kinetico Water Systems

Family-owned De Anza Water Conditioning sells, installs, and services Kinetico water softeners, whole house water filters, and reverse osmosis drinking water systems. Kinetico products are the only patented, non-electric, demand-generated water treatment equipment manufactured today. Additionally, the Kinetico water softener is truly unique, being the only one on the market today that delivers an uninterrupted supply of soft, conditioned water, while competitors interrupt the supply during the regeneration cycle, thereby exposing your infrastructure to the harsh effects of hard water. Our small-footprint, high-efficiency, low-maintenance Kinetico Water Systems are able to deliver the quality and volume of water you need to service your entire home or business.

Kinetico products are tested and certified by the Water Quality Association (WQA) for safety and performance in accordance with all applicable industry standards.
