I am so impressed with this team. Raul came out to our new 'old' home (built in 1946) to help us navigate several water issues, including the lack of a main shut-off valve. He followed up immediately to ensure they could handle the installation. Aidan Henderson was our amazing installer. He spent a considerable amount of time explaining the process and discussing the various scenarios that might arise with an older property. He took our concerns seriously and provided thoughtful, effective solutions. Aidan is clearly experienced and knowledgeable; he was responsible throughout the process and never took shortcuts. I don't usually write reviews, but this exceptional service earned one. Thank you! One very satisfied customer. read more

Anyone that needs a water conditioning system DeAnza Water conditioners are wonderful and excellent product. I've had mine for years. read more

We contacted them through yelp which also brought a number of other businesses. They were the second of 6 that came in. Tam was straightforward and clear with his product with very little competitive bashing. Straightforward enough that I was ready to sign. But no, I have 4 more companies come in. I realized that the engineering of their unit is good. It does not have all the reporting and smart home features but I am not sure I want that. I want a water softener to work. The tech was accommodating. Discussed the unit placement. We ended up putting it outside versus under the house. He was great, easy to speak with and knew the best way to do the install. They installed the reverse osmosis machine as well and it was done well. I now know every major manufacturer of reverse osmosis's and water softeners. I can say the mechanical only approach is the best. I can also say de Anza is a solid firm and treats customers well. I should have trusted the yelp rating and not looked at 4 others. Thanks Tam and my installer and the scheduling team. They are easy to work with. read more

We've had hard water for years, and it has taken a toll on our appliances and our soap consumption. We talked with a few soft water service providers before deciding that De Anza Water Conditioning offered the best system and services to meet our needs. Everyone from De Anza Water Conditioning who visited our home to assess, plan, and install the water softening system and reverse osmosis water purifier (for the kitchen) listened to our concerns and implemented a system that worked within our many constraints. Special thanks to Raoul, Dylan, and Jonathan for their care and professionalism. read more

Had an amazing experience with De Anza Water installing my water softener and RO water system. Tam helped me on the sales side and seriously made everything so easy. He explained the entire process from point A to point B and took the time to answer all of my questions without making me feel rushed. Aidan and Jose were the technicians who did the install and they were awesome. They showed up on time, walked me through my entire setup, explained exactly what they were going to do, and made sure everything was done clean and correctly. Before they left, they also explained how to maintain the system which I really appreciated. It's only been a few days and I can already tell a significant difference, especially with my skin. Super happy with the whole experience. Thank you guys! read more

Jose was professional and thorough. He was on time, performed the work very cleanly. I recommend his services.

I vetted a whole bunch of water softener companies, and De Anza Water's product resonated with me the most. Trust me, I love electronics and IoT devices more than the next guy - I even have a toaster that's connected to WiFi, but I did not want to have to be bothered changing settings of a water softener if we were ever going to be away from home for an extended period of time. Raoul did an excellent job making a compelling case to go with them, and Aidan did an awesome job installing the water softener as well as the K5 RO. My wife and I cannot be more pleased with the performance of the water softener and RO. Listen, you don't need to hear more from happy customers like myself; just do yourself a favor and schedule a consultation with them and see for yourself. read more

Benjamin Rodriguez came out to perform a repair for our 8 year old Kinetico K5 and was outstanding. He came on time, and I really liked the tracking app where we could see a map showing us how close he was to arriving. We had a leak on the top manifold, and upon arrival. he diagnosed it quickly and repaired the leaky valve in about 15 minutes. Five stars all the way. read more

The team was professional and completed the work quickly. I appreciate how they took the time to explain different options with me, without rushing me to make a decision. Benjamin was great and very polite, and make sure I understood the system after it was installed. read more

Mario, Answered all my questions about the water softener system and did a great job. He and his team member were courteous, organized and clean up after the job. Even the front office (Kim) help me with the payment process. read more

Dylan was very professional and friendly who helped us with installation of new RO system. We had problem with our pipes and he even went out to get the part for us to fix the problem. Overall it was a great experience. Thank you! read more

Benjamin did an outstanding job installing the Q850 system for us. Beyond the installation itself, he went above and beyond by helping resolve additional water leakage and air-gap overflow issues. There was some internal miscommunication noted in his work order stating that the ice line was not included in the scope, which was unexpected since I had written confirmation from the salesperson that it would be included. This came as a surprise to Benjamin and had the potential to delay his next project. Despite this, he remained professional and patient, completed the ice line installation for the A200 filtering system, and thoroughly addressed all of my questions about the systems. I'm very satisfied with the service provided. I look forward to following up later with feedback on our experience using the softened water and filtered drinking water. read more

I doggedly researched whole house water treatment systems. I am on a very large community water well system, O'Connor Water Tract which is high in manganese and very hard water. I chose the Kinetico system which does not require power and does require salt bags to be added occasionally. I have had it about 10 days and notice a positive difference. I also have the Kinetico A200 RO under sink system for dedicated drinking water and it's great. Bottom line is I do recommend the Kinetico system especially if you have hard water and want a kinder water experience. I did the research so you don't have to... :]] read more

Deanza Water Company absolutely crushed it--from sales through implementation. Tam was very helpful and the sales process was clear, honest, and zero pressure. They took the time to understand our needs, explained the options in plain English, and made sure we felt confident in the solution we chose. Benjamin led the installation of our water softener and was just as impressive. He showed up on time, worked efficiently, and clearly knew his craft. Everything was installed cleanly and professionally, and he walked us through how the system works before leaving. No rushing, no shortcuts. The difference in our water quality was immediate--softer water, better tasting, and a noticeable improvement throughout the house. You can tell Deanza truly cares about both the product and the customer experience. If you're considering a water softener, stop shopping and call Deanza Water Company.

We had the carbon filter, water softener, and reverse osmosis system installed today. Jose was very professional and helpful in explaining the operation and maintenence of the system. He worked straight through to have it all done in a relatively short amount of time. This is the easiest system that I have ever had to work with. Great value over the long run. read more

Super happy with our new RO system! Our sales person, Tam Doan was very friendly and knowledgeable as he helped us pick the right system for our household.

We had an RO under-sink filter (Kinetico K5) installed by Kai and the process was seamless. As renters, we weren't sure if we could get this done but with the increased levels of Chromium-6 in our city's annual water reports, we eventually decided it was worth the effort. And it was actually very little effort. Kai explained step by step as he was installing everything so we could figure out how to make sure everything was returned to normal after we vacated our rental in the future. He was fast, clean, polite, and good at his job. We are very picky with installations and he even reinstalled a the spigot from scratch once he was finished with the first installation because our sink had an odd installation feature which required he include this sort of plastic cap to make it perfectly aligned. I don't know the terms to describe how he did it, but he took the extra time and it looks perfect. He even trimmed the gasket so no extra was showing under the spigot. Thanks Kai! read more

I wanted a water softener system for the whole house and ended up calling De Anza. Jose Hernandez was a treat to work with from De Anza. He explained everything thoroughly. Installed it all with no problems. And was a joy to have around during the installation. The salesman Raoul was also a pleasure to work with. He didn't try to upsell me and explained everything in detail and gave me all the options. Would use them again in a heartbeat. read more

I am so so so happy with my new water system. I was skeptical at first because I had purchased a Lifesource water system 7 years ago and it did nothing for my water. In my area, the water is incredibly hard. De Anza sent Chris Emam to install my water system and the under sink RO system. It took a few hours, but since my tandem garage is so tight, he got crafty and did some carpenter work to get it to sit nicely on the side of my garage. The plumbing work was super clean. He was detailed and friendly and made me feel confident about my choice. He also took my old system to dispose it for me. It may seem pricey, but they threw in the RO system under the sink for free. I wake up everyday now and I can't believe I have good water. So worth it. read more

Mario Contreras did an excellent job with the installation of our Kinetico water softener and RO filter. Mario was respectful and communicated well about every step in the process. He answered my questions thoroughly. I have really enjoyed my entire process with DeAnza Water Conditioning. They came highly recommended by my neighbor and I can see why. read more

Extremely pleased with both the water softening system and under-sink water filter after 3 months. As one example, I attached two photos of the same glass but one has been washed in the dishwasher before the water softener and one has been washed after the water softener. It's actually clean now?? I'd also love to shout-out our technician, Tomas Romo, who was extremely nice and professional, and who found a way to do an optimal installation with minimal visible pipes etc. He even went above and beyond to do this despite some difficulties in our crawl space. read more

We love our water filters. The Kinetico system is the best there is. De Anza water has such great service. I love the service. They are extremely fair, and they bring out my filters to me when I'm in a rush. Whoever does the filing does a great job, they always have my info ready to go. I forget if I bought two filter sets or one last time, but they can tell me in a wink. We just had a second system installed and the installer - Chris - was top notch. We accidentally had him install the wrong faucet and had forgotten we hadn't even purchased one. Chris said no problem, and like Santa Clause he went out to his truck and got the most perfect matte black faucet! He installed and uninstalled one faucet, then installed a second like it was a huge pleasure. He put a water sensor, a tray, and tucked everything neatly under the sink. Then he showed me how to maintain the system, and gave me a STELLAR tip on changing the RO filter that had been plaguing me every time. read more

Quick and well done from quote to install. Benjamin did a great job putting in the unit and got it exactly where I wanted it (which was in a somewhat narrow location). The water has been fabulous since - all the hardness and iron has been removed. Amazing job and many thanks to Benjamin. read more

update: I want to update this review based on De Anza's follow-up of my original post. They reached out to me the day after I wrote the 2 star review and sincerely apologized for my experience. They also sent another technician to my house on the same day double checking everything and gave us a new set of filters. While the water damage to my kitchen cabinet can't be fixed, I appreciate their swift response and professionalism. -------- original--------- De Anza Water installed Kinetico softener and RO filter at my place last Wednesday. I initially had a good experience with the sale agent and installer who were really friendly (I give 1 extra star for that) However, just 2 days later, on Friday I noticed large volume of water leaking under the sink where RO was installed and causing water damage to my wife's favorite cabinets. When I called them, instead of assuring me the situation would be handled, dispatcher emphasized to me that there will be extra charge if the leak is not caused by them. And they initially planned to send someone to me on Monday, that's THREE days after we already notice a water damage. Eventually another employee was able to show up on Friday afternoon(I do really appreciate that) and fixed the leak that was caused by a loose connection. He did agree that such a level of leak should have been noticed during the installation if it already existed before Wednesday. However, he insisted that the leak is not caused by them, because it's a hot water pipe that they don't need for RO, despite the fact that the pipe is in a convenient position that someone would definitely touch to finish the installation. I've attached the photos so you can make your own judgement. I wanted to like them, they had good review and good initial attitudes which seems to warrant long term trust. I picked them even when they were the most expensive choice I got, and I told the installer that I will leave fabulous reviews, which unfortunately I can't do anymore. What's worse is I'm stuck with them for next 6-10 years since Kinetico is proprietary. It's too late for me, but I suggest anyone seeing this message to avoid locking yourself to such a proprietary products, and absolutely check for leakage several hours after any plumbing work. read more

I moved to San Jose a few months ago and did not realize how hard the water is here! I wanted to make sure our appliances could continue to run smoothly so made an investment in a water softener. I had some door to door salesman from various companies reach out, felt pressured by their sales pitch, and ultimately refused them because of cost and ongoing maintenance. Instead, I did some research and stumbled upon De Anza because of their stellar reviews all over Yelp and Google. Raoul was great in explaining the benefits of the system and showing me the difference in water hardness. I use way less soap to get more of a lather than I was currently, and now no longer need to use a water filter for my espresso machine. The install is well worth the value knowing that De Anza has been around for decades and will continue to give support. Benjamin did a great job finding the optimal installation spot for the water softener and faucet for the reverse osmosis system. He even installed an access for hard water before it goes through the system so I can easily fill up a watering can for my plants. Overall, the demo took about 45 minutes. The install was scheduled a week later and was completed in about 7 hours. The team is super friendly and is more than happy to walk you through the process. Highly recommended and a great trustworthy business. read more

At our previous home, the water was so hard and constantly left water rings, marks, and calcifications everywhere! The water did not taste drinkable either, therefore we resorted to drinking out of plastic water bottles (which is super wasteful and costly!). Fast forward to moving into our new home, we knew that getting a water filtration system was a priority. I didn't know the first thing about water filters, and our consultation with Tam made me feel more at ease. Not only was he incredibly friendly and knowledgeable, he addressed any questions and concerns we had. Niko also did an amazing job installing the filter, which fit perfectly next to our water heater in the garage. We instantly felt a difference in our water quality after the installation. Now I can confidently drink water straight from our tap and no longer need to deal with calcifications! Thank you Tam and Niko for making this a great experience :) would definitely recommend De Anza Water!! read more

I recently purchased a house in Morgan Hill and needed a water softener. I've heard great things about the service and product from DeAnza water. I spoke with Chris Tran, who was very knowledgable about the product and gave me a thorough explanation about the products that they have. He walked me through what the installation process was going to be like and what to expect from the product i was purchasing. He was very patient, friendly, and easy to work with. All of my questions were answered and i was very pleased with the assistance. At the end of it all, i felt confident about the purchase and that was all thanks to Chris. On the day of the appointment, Dylan stewart came by to install the water softener. He was very friendly and knowledgable as expected. He also installed the reverse osmosis for my sink. He gave a good suggestion on placement and confirmed with me before anything was done. Everything turned out great and after he gave me a good explanation about maintenance and also referred me to some of the company's videos in case i would forget. Everything was cleaned up and no mess was left. He even stayed around to make sure no leaks. The whole installation took only a couple hours. Dylan was an amazing tech and i was happy to be able to have him for the installation. Overall, great customer service and amazing employees . i will be recommending all of my friends and family to DeAnza Water for sure! read more

Purchasing a new water softener isn't something I expected to do on a regular Tuesday--but I'm really glad I met Dylan. As a first-time homeowner, I appreciated how friendly and approachable he was. There was no pressure or hard selling at all. He took the time to explain how water softeners work and gave me a clear picture of the water quality in my area. Dylan also inspected my existing setup and walked me through several affordable options that would work for my home. The installation itself was quick and smooth--done in about two hours--and afterward, he patiently explained everything I needed to know about maintenance. Highly recommend if you're looking for honest service and professional support! read more
