John Schafer

Family-owned business for four decades.

Almost four decades 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 water— the benefits of its best and the challenges of its worst. To compete in this industry, John knew that he needed to provide customers with 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.

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.
