We’re proud of our services and don’t like to brag—but
we like it when our customers do.

Here’s what our customers have to say…

We are very happy with De Anza Water Conditioning’s professional and timely execution of its installation.  Each and every member of their team did a great job.  Thanks to Ian for staying on top of things!

From start to finish, the most professional company I have ever worked with and who only sells and installs the most superior and highest quality water treatment systems available!
San Jose, CA
I love the taste of the RO Water!!! It’s so much better than the water straight out of the tap.
Cupertino, CA
We love our Kinetico Water Softener! Installation was quick and easy. The installer was professional and explained the installation and care of the unit. I wish we had installed a Kinetico water softener years ago! We saw results the same day. No more hard water stains! Softer skin and hair!
