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.

Our Kinetico system was effecting a major water leak (600 gal over ~28 hours), and I tried reaching them at different numbers after hours; a representative contacted me from each of those lines and set up an appointment the following day, 8a-12p window. Our technician Sonny Vigil arrived at 9AM, very professional and respectful. He explained his triage per step, replaced parts and fixed everything up without hassle. Shared tips about the filtration system and general troubleshooting. He additionally performed a full system checkup and replaced our filters as part of the same service visit; we would've otherwise run out of potable water shortly. Serviced everything efficiently and effectively. I had originally planned to get to work in the afternoon, but everything was resolved and ready to go by 10:30AM.

Very disappointed with the communication and overall service from this company. I was told one…read morething, while my tenant was given different information, which created unnecessary confusion. After the technician completed the filter service, my water filtration system was not working properly. I contacted the owner expecting them to stand behind their work and help troubleshoot the issue. Instead, without performing an official inspection of the system, I was quickly told that the resin likely needed to be replaced and was quoted approximately $500 for another service visit. My system is only about 5-6 years old, so I was concerned that such an expensive repair was being recommended without properly diagnosing the problem first. We later discovered on our own that the actual issue was that the filtration system settings had not been set correctly after the technicians changed the filters. Once the settings were corrected, the system worked. My biggest concern is the lack of communication and proper troubleshooting. Before recommending a customer spend another $500, especially immediately after your technicians serviced the system, I would expect the company to first verify that the work was completed correctly and that the system settings were properly configured. Unfortunately, based on my experience, I would not recommend this company.

I felt a bit bad about asking him all sorts of questions years after the job was done but he always responded quickly, enthusiastically, and professionally.

I can't recommend Silk Water enough. Trung (the owner) is a licensed plumber who has the skils to…read moreprobably take on any plumbing job but he decided to focus on wafer softener/filters only. "I don't have a drain", "I don't have a soft water bypass", "Will soft water kill my plants?", "There is no electrical outlet nearby", "Will my water pressure drop?". If you are like me, you will be putting off installing a water softener because you are stressed over these things. My advice after this experience - DON'T. You don't realize how you have "tolerated" hard water until you finally experience soft water. The "feel" (for lack of a more scientific term) is just so different. And Trung will take care of EVERYTHING from start to end, in what is overall a very stress-free experience. He installed a sediment filter, a carbon filter tank, a 46 grain water softener, created soft water bypasses for all of my outdoor irrigation, a bypass for the whole softener/filter system in case anything ever goes wrong with it, and a drain (with p trap and air gap). He had a buddy who helped with installing an electrical outlet (also licensed). I was specifically looking for a softener with a Clack WS2 control valve (reputed to be highly reliable) and Trung supplied that. In fact he supplied everything. He also tested my water hardness to ensure I was asking for the right things. Price, quality of work and timeliness was 11/10 (I will add that his price is substantially fairer than those general plumbers who will quote you 10k off the bat - the audacity!). But here is the differentiator - Trung's sense of accountability. Everytime I requested something, I would apologize... but his response? "No problem it is my job". Wow. Please give your business to Trung. This is a 100% genuine review from a 100% grateful and satisfied customer.
