DeAnza Water is our local water softening company and I'm glad we chose them. Our technician,…read moreBenjamin and Salesperson Raoul were extremely helpful throughout the entire process of getting our system installed. We really appreciate the thoroughness in explanation and responsiveness of the office. The kinetico system also feels great because it draws no power and we don't have to deal with regeneration interrupting water use every so often. Great value considering we got piping for a bypass valve done as well. Would recommend!

De Anza Water Conditioning installed a water softening system and reverse osmosis (RO) filter…read moresystem in Spring 2026. The installation includes a 1-year service warranty, which has proven very helpful. Side note, if you add a mineral cartridge to your RO system and that RO system supplies an existing copper water/ice line to a refrigerator, be sure to have the ice line replaced with polyethylene tubing. If not, the minerals will degrade the copper ice line, resulting in leaks. Many thanks to José for the super job he did capping our old copper ice line and replacing it with under cabinet-mounted polyethylene tubing--works great, can't see the tubing, no leaks! Many thanks to Niko for resolving a problem we had with melted potassium in the reservoir tank for our softening system. Niko was very patient as he explained the problem and showed me step-by-step how to fix the issue myself if it happens again. He also tested the water until the results confirmed that the problem was resolved. Many thanks to Angel for taking service calls cheerfully and with kindness and efficiency. I really appreciate the great service my family has received from De Anza Water Conditioning. I would hire them again without reservation.

I contacted the company and complained about how long it was taking to receive my order. They…read morechecked into the problem and as it turned out the issue was with the California(CA) United States Postal Service(USPS). I checked into that as well and there is definitely a problem there. Even listened to interviews where employees described mail and packages sitting in distribution locations for over a week. And the new California Postmaster General has made cuts to save money but also severely damaged the service reliability of the CA USPS. In summary the delivery delay is not the fault of the Clean Water Systems & Stores. The Clean Water Systems & Stores sent another package of the same parts, at their cost, via UPS, which did arrive promptly!

About a year ago my Rheem water softener died so I decided to up my game and purchase one from the…read moreClean Water Systems because I thought they would carry a better product and I would get better service if needed than from a big box store---NOPE! First-I paid almost 3 times as much for the system than if I would have purchased one from Home Depot or Lowes. Second-The installation I had done on this new product was done by a pro and the programming of the unit went well. Third-Soon after the system was installed it began doing erratic things like regenerating at different times than the one that was set. The regeneration time was cleared and reset multiple times only to have the softener revert. Fourth-I called and Emailed the customer service rep. and he tried to correct the regeneration problem by walking me through the steps but none of those fixes worked. He then contacted the manufacturer and they responded with a new fix but that did not work either. Fourth-The owners manual is THE WORST!!! It is just a cobbled selection of random instructions, almost like you walked into the middle of a conversation and then try to understand what is the gist of that conversation. Early on when I commented on this I received a call from someone at the Clean Water Store and she wanted to know and understand how they could improve the manual. I suggested she look at how Rheem or Whirlpool or GE does it. Their instruction/owners manuals whether printed or online are clear and concise. Doing so would probably eliminate many questions and Emails to the service reps. Fifth-Here I am a year later with an outstanding service ticket. A few days ago the rep. contacted me and said he was going to close out that open ticket. I replied the manufacturer never helped us correct the regeneration problem. He stated, they never got back to him. Sixth-My impression and experience shows that once you purchase from the Clean Water Store you are on your own. The service rep. tried his best but like me he was left in the lurch. The warranty on the product from the manufacturer is worthless, it means nothing. The owners of the Clean Water Store should take heed, they can not ignore ongoing product problems that affect their customers. If they continue to not serve their customers, their customers will find a company that does. STAY WAY! You would be better off throwing your hard earned money in the street.

My family used to drink LOTS of individual bottles of water, but we got sick of hauling it from…read moreCostco and then having to deal with lots of empty plastic bottles. I looked into getting water delivered in jugs from Costco, but I didn't like the idea of being locked into a subscription plan for the water AND paying them a monthly fee to rent the water dispenser. I found Paradise Water and they've been great. I just send a text message when I'm running low, and they deliver exactly the jugs I need to my house. There's no subscription, so if we need more or less it's no problem. I ordered a Bottle Buddy water bottle stand from Amazon, which has been a great solution. It's cheaper, the water tastes good, AND it's more environmentally friendly.

Jose is responsive and very reliable! After sending him a text to request for waters, I am able to…read moreget waters the next day, or at the latest, within a week which is great service. I have requested water deliveries in San Francisco and Oakland and all deliveries are smooth. He delivers the waters to your apartment, which is much better than lugging gallons of water from the store to the apartment. Would recommend!
