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.

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!
