About

Water Purification Equipment
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 10,000 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.

    Benjamin came to remove our previous water filter that was not working well prior to our install of new system through DeAnza. He came when we were not home, into our garage, left the place tidy and finished so quickly! Thank you so much

    Benjamin did an excellent job installing our water conditioning systems. He was meticulous and did not hasten the installation. He completed the install in the said time and also explained how everything works and how to maintain it! De Anza also did an excellent job showing me the options for water conditioning and also tested our water.

    Great company for your water system service needs. They are friendly and reliable. Their technician Mario Contreras was very knowledgeable of the service needed to be done. First thing he noticed water softener filter needed change. it was all black inside. After he finished this task he moved to our drinking water filters and replace those as well. He kept the area wet free!
