One Water Systems in Carlsbad, I love my water system and the service at One Water Systems , it's great to have clean water throughout the whole house.... Open

We switched from Culligan (see review as to why), and purchased One Water. I cannot tell you how HAPPY I am that we did!  First of all, they are very professional, extremely knowledgeable (not just about their own system, but told me why other systems like Culligan are unable to perform well), and reasonably priced. But the water??!  The WATER IS CLEAN!!!  We have had countless allergies and skin issues from San Diego County water, but NOT ANYMORE!! (Doing the happy dance!). Research before you buy from any company...or call One Water and they will come to your home, give you a full presentation (with charts and visuals), and even test your water (Culligan did too, but they suck as a business, so there's that). I am happy and healthy now, thanks to their magnificent machine! Open

This is the way all companies should be run!  Owner is responsive and i can promise you that they WILL call you back!  In these days its rare that a company is so responsive! Our water system is two years old but we have really been using it for the last month full time, so far so good!  As an informed consumer, we looked for the best reviewed whole house water system and i think we found it!  The company NEVER claims this is a soft water system!  Its exactly as advertised, its a water conditioning system....

We have had our system just under a month now. We live it. The water is amazing. So much better then the old salt filtration system we had. The whole family... Open

Did order one for me and my brother and it's the best water filter available. My wife loves the taste and the feel of her hair in the shower. My daughter had a rash before the installation, from the chemicals in SD water and now all gone. Thank you for the great service and product. We will continue telling all our family and friends that they need one.. This is great and everyone agrees. Open

I have been singing the praises of One Water ever since our unit was installed in 2012.  Prior to that time I was an Evian addict and never considered a water system.  Since then, I have enjoyed great water for drinking, cleaning and for a generally healthy environment.  Further, and equally important has been the service following the purchase.  One Water has contacted me for period tests of the water to insure continued purity. Finally, an issue I had with a bypass valve was solved with an on-site visit the same day I called for help.  These are people with whom you want to do business. Open

We just had a One Water filter installed in our house and I have to say, it's incredible! Prior to installing it, we had a strong chlorine/chemical taste. Now, I literally drink from the faucet every day and it's truly unbelievable how good the water tastes! I now have peace of mind bathing our newborn in water that I know is clean and healthy for her skin. Thanks Kevin and everyone at One Water Systems! Open

Management, Kevin, and installer were everything one could hope for. They were punctual, profession able and personable. We love our system. All the hard water spots are gone or ever. Could not have asked for more. Open

We are so pleased with our new water system from One Water. They were professional and helpful with answering all of our questions and we love our new system! The installation was quick and easy as well. Thank you One Water System! Open

One Water Rules!!! I decided to go with this system because of the low maintenance and warranty. The cost is slightly cheaper than a water servicer overtime and we do not have to worry about the soft water killing our plants and making our animals sick anymore. We have been drinking about 3-5 cases of bottled water per week and now, I only buy it to keep on my work truck.  The water from this system tastes great! I have drank water ranging from the High Sierras to the Mohave Desert and beyond. Tap water, well water, all bottled water services, store bought water, cactus water, river/stream water and rain water...some of those made me sick, ruined my clothes, destroyed pipes, water-heaters, dish-washers, refridgerators, coffeemaker machines, faucet valves and fixtures and the like in my previous residences...I just got sick of replacing, rebuilding and fixing items in which fell victim to natural and municipal water. I am anticpating an annual savings of $800-$1800 in plumbing repairs alone.  Imagine what that stuff is doing to us on the inside...One Water System's staff answered all of my questions, was courteous, prompt and professional. I highly recommend the One Water Whole House System for anyone considering or not yet considering a truly worth it water conditioning system for their home... Open

Now, a month later, we're even more pleased with the system. All promises made have been fulfilled. It is so wonderful to have pure drinking water from every faucet in the house. No more bottled water or filters for the refrigerator. You can "feel" the softness when you shower. For showering and, especially, for laundry, less soap is necessary. Laundry comes out much cleaner looking. At first we had spotted glasses coming out of the dishwasher but Finish JetDry has taken care of that. Our very old dishwasher now does a much better job. We've always used Clorox tabs in the toilets and such are still necessary, probably even more so. But now there no longer is a hard-water ring in the toilets. No special cleanup necessary. All in all, we think we've made a terrific investment. Open

I have had the One Water system for 1  1/2 years now. I wanted to wait before writing a review, to make sure I was really happy with it first. Here's what I've got to say: ~Great tasting water in the entire house. I like being able to get up in the middle of the night & drink from the bathroom sink if needed. Call me crazy, but I also like drinking it when I'm taking a shower too lol. ~There has only been one person in my entire 1  1/2 yrs of ownership that says he can tell that it's "tap water" & tastes weird. However, he has a hangup of not drinking water unless it's out of a store-bought plastic bottle, and he has other weird quirks too, so I discount his complaints lol. I have a huge extended family & friends and they all like it. ~No more carrying heavy jugs from stores that sell filtered water. I had a shoulder injury and lifting those 5 gallon jugs were killing me! ~No more water cooler taking up space in my kitchen. ~Yearly service calls, and they remind ME when it's due...no chasing them down. ~LOVE LOVE LOVE that there's no chlorine. I noticed an immediate difference in my hair and skin. In fact myself and 2 sons all had weird rashes on our skin (and kids on scalp too). I had an elderly friend move in before I bought the system and she got the same skin irritations within one week. So I knew it was our water. After the system was put in, my skin cleared up within a couple weeks, my elderly friend within a few days, and my kids' skin was clear in a couple weeks, scalp a couple months. ~Everything stays cleaner longer. I don't have to scrub as hard to get grime off my shower, sinks or toilets. Dishes/dishwasher is cleaner. Laundry is cleaner. I never thought to do this before, but I just stopped using fabric softener 3 weeks ago, and haven't noticed a difference. I could have been saving money all along lol. ~I had to get my tank installed outside, so they put the pipes to drain out onto my lawn inconspicuously, so it wouldn't be wasted but could water my lawn when it went through the clean cycle. ~Speaking of clean cycle. I read the other reviews that talked about how bad it is to remove the chlorine. When they install the system they set an auto clean mode, where it flushes the entire system on a regular basis, thus clearing out any possible bacteria in your tank. I think they based it on how many of us lived here and our water usage.  The water doesn't sit in your tank or pipes stagnating for 5 yrs growing bacteria like the reviewer stated. I know my water would taste nasty after 1  1/2 yrs if there was that much bacteria festering in it! ~I kinda forgot about the system until one day I noticed my water tasted like chlorinated disgusting tap water again. I called and a tech came right out & figured out the problem (a house sitter had turned it off thinking it was broken when water drained during the clean cycle). He reset it to drain every 5 days instead of 7, and I have liked it even better now than before. ~I called the company based on my own search, the owner came out and zero pressure! I find it hard to believe the reviews that said he's high pressure, because I got nothing of the sort. ~I wish it cost less, but considering it has a long warranty, and is still less money than some other filtration systems out there, has no upkeep of salts or under sink systems to worry about... the price of my system is worth it to me. I know I can think of other reasons why I like this system. But this seems like a thorough enough review! :) Btw, I did not know anyone at the company before calling by myself to inquire about the system. I'm not writing this review as a friend of the owner, like some other reviewers are accusing. The owner is very nice, and the plumber and tech have been great too. But I have had zero contact with them of any sort, except with this purchase. I'd buy this system again if in the market looking for one! Open

For you one liners:  noteworthy from A to Z! For the rest:  Kevin and his staff at One Water Systems are awesome.  Many months ago I called One Water to ask some questions about my existing water softener.  The owner (Kevin) not only answered the phone and my questions, but volunteered to come out and give me a free water and air test. He arrived promptly and analyzed my water.  He educated me about the problems with a water softening system that used salt.  He also educated me about the reverse osmosis system that I also had.  He then analyzed my air quality both inside and outside (around) my house. Next came the recommendations.  He never tried to sell me anything or use those high pressure sales techniques on me.  His passion for what he was doing, the systems that he sells and believes in sold me on getting some of what he had to offer. I then agreed to purchase both the air and water purification systems.  However, my budget was a bit tight and although O had agreed to purchase the systems and had a scheduled install date, Kevin put my order on hold until I was ready!  WHO DOES THAT??? Anyway, fast forward 3 months and as of today, I am the proud owner of a One Water purification system as well as a Healthway pure air system!  The installer was awesome as well, he knew his stuff and was very thoughtful and thorough. I don't want to steal Kevin's thunder by telling you all the specs, and features of these systems, but my quality of life is already improving.  My shower was awesome, no residue.  I tested the water tonight with some fish strips and it is right in the middle, not to low or high on the PH level.  I could go on and on, but let me close by saying, if you have any health issues, especially regarding breathing, allergies or skin issues, then you should give One Water Systems a call! Thank you Kevin and One Water Systems for your kindness, knowledge, passion, patience and professionalism!  5 stars all the way!!!!! As perfect as it gets! Open

We found out about this system at a Home Show in Del Mar.  Kevin came over to our home and checked our water, identified the potential location for the filter and answered all our questions (we had many!). The system was installed right before Thanksgiving by Juan and Gerardo.  They expertly plumbed (our regulator was in a tricky location) the system and took their time to make sure everything was working properly and explained what to expect over the next few days. It's now a month later and we are tremendously happy with our clean water! No more moldy tasting water, no more stinky water, no more bottled water :-) The One Water Systems team has been professional, friendly, and flexible. Open
