Know what’s in your water with a free, fast, and accurate water test from DeAnza Water Conditioning, Inc. We offer free basic water testing in most local areas. We offer this basic mineral testing in most local areas.

Water Softener Systems

Water softeners remove extra mineral ions in your water, ensuring you don’t encounter hard water problems in your daily activities. DeAnza Water Conditioning, Inc. solves all your water softening needs, from water testing to installing the water softener and maintaining the water system to ensure your home or business gets a constant supply of quality soft water.

Reverse Osmosis Drinking Water

Protect your health with clean water purified with reverse osmosis technology. The semipermeable membrane in the system traps contaminants, and odor-causing impurities, leaving you with clean and odor-free water. Iron and hardness will need to be treated before reaching the reverse osmosis system.

Specialty Filters

Water problems are no match for our specialty solutions. Our systems can be used on well water or city water. Kinetico specialty filter systems will eliminate impurities, such as iron, sulfur, manganese, and arsenic, restoring your water to its most pure state. Kinetico Water Systems can take on and solve virtually any water problem.

Honestly, over the years of calling De Anza Water for service was never a headache.  They had always been responsive and came on time and when they said they would.  There were never any surprises.

When I sold my house recently, I needed to fix the Reverse Osmosis unit because of a leak which was due to the housing of the unit, no big deal, really.  I worked with Jennifer Administrative Assistant where she never ever left me high and dry.  She responded very quickly, was completely behind what she said, and she helped schedule an appointment with the new owner.  She is the best!!!

The unit is fixed and working properly! Thanks so much for the great service over the years!

I was looking for a good water softener for a long time. I finally had enough with hard water for water stains and hair loss. So I started shopping around again and read some good reviews about Kinetico. DeAnza was very knowledgeable about water softener and understood my concerns about using soft water for irrigation and proposed a perfect solution to install another irrigation pipe directly to my backyard. Considering all the unique features of Kinetico and my concern was resolved, I hired De Anza water to install a refurbished system.

The system looked very nice in my garage. They showed me how to by-pass the water softener to clean the water filter and also mentioned that where the system might leak. So far the system is working perfectly and I cannot be happier with how my water now feels.

Our family chose De Anza Water Conditioning for many reasons.  They were extremely responsive to my online Yelp quote request, super friendly on the phone, and they carry a very high end product.  They are an authorized dealer of Kinetico which is basically a 2 for 1 product you get soft water all the time and all of your entire homes water is filtered.

Installation was super easy and fast.  Plumbing was routed very efficiently and clean looking.  It took only a couple of hours to finish the install. It has been a little over a week now and we can definitely taste, feel, and see a huge difference. Soap is super bubbly, water taste is amazing, our hair is softer more clean feeling.  We are really excited about our water quality now.  In honesty I was not expecting this big of a difference.  We don’t like to mess around drinking and showering in poor quality water.  Thank you De Anza.

Mountain View, CA

Kristine L.

Requested De Anza Water to service our water softener and change out the whole house filter, and reverse osmosis water filters.  When our tech arrived, he suggested the possibility of replacing our 20 year old water softer. Technology has improved the softener to use 30% less water, 30% less salt, and less energy. Sounded like a win to us. We’re glad we did it! I’ve been with De Anza Water conditioning for 20 years. We always find them to be 5 stars for us.

De Anza water has been a great solution for a filtered water system for our office! They are professional and responsive, highly recommend!

San Francisco, CA

Karen M.

I highly recommend De Anza Water to anyone!! Great customer service!!!

We just had to place a service call (for something we caused… we still love the Kinetico system!!). Making the appointment was easy. We really appreciate that we got a message when our technician was on his way. It had his name, photo and a link to see how far away they were and when they would arrive.

They were so thorough with everything and respectful of our property!! And provided helpful info for extending the life of the system. 

Sunnyvale, CA

Vicki A.

I was very happy with the service and support from De Anza Water conditioning. Their package and service was not the least expensive that I considered but I was impressed by the long term support they provide their customers. I had a lot of questions and our sales person Tam was patient and addressed all my concerns. Installation went smoothly and I am SO happy with the system and the quality of our water.  I highly recommend De Anza Water.

San Jose, CA

Shijavi P.

Flow pressure of water is not compromised either, while ensuring great quality filtration and softening. Equipment does not use electricity either, compared to other brands that use electricity. Maintenance is not required every year for softener compared to competitors. This is a high quality product. Although expensive than other cheap brands, quality speaks for itself. In long run that additional expense does pay off.

Sunnyvale, CA

Catherine P.

I just LOVE these folks!  They have serviced my water softener for the better part of the last 15 years:  they are always on time, they are always thorough, the price is always what they said it would be when we scheduled the appointment, and they are always professional.  Patrick came out a couple weeks ago to change the carbon.  When he was doing it, he noticed a couple problems with the water softener and so he just fixed them without any extra charge.

Anna S.

We have been drinking their water since moved to California. we didn’t like the hard water and the quality, found De Anza Water and learnt that we could get water softener and filtered drinking water installed, we decided to go this path. They came out, got everything installed, Patric, the installer is extremely knowledgable and helpful, he’s really clean and efficient, got everything done in 4 hours! Now w can’t wait to take it first shower with this new water softener! If u want get good quality water, bath ur kids and take care ur water pipes, go to De Anza water!

Santa Clara, CA

N F

We have been a client for 10 years for water softener with De Anza and very happy.  After doing a lot of research, we had Kinetico RO put in for drinking water and LOVE the system.  It is amazing.  John came out to our house for consultation and we really learned a lot from him.  The water quality Exceeded our expectation.  Mike installed the unit and he was superb and we thank him for his amazing work.  Thank you John, Lynne, Mike, Judy and Ian.  The customer service is great.  If you are really looking to get an RO system, this is it.  It is expensive but WORTH IT. Every time I drink it, I think of John and how passionate he is about his work and company.
