    Professionally installed
    Daryl N.

    The engineers were reasonably prompt and very concise with the water softener replacement options and considerations. They handled much of the disposal and installation, as well as the preparations for the replacement. They got to work right away on the day of the job. The price is what you would expect for a full replacement of the water softener and salt container, but we were shown the features to back it, such as better filtration and easier maintenance. The project was fairly painless. We look forward to working with them in the future.

    Thank you, MCS water technologies

    The technician was outstanding willing to get the job done, clean, correct and efficient and the products are very good. We've used them for years.

    I had water filter system installed by MCS Water before so immediately contacted them when I need a water softener system. Michelle, the sales representative, was knowledgeable and patiently explained and answered my questions and concerns. The technician who came to do measurements gave me valuable advice on how the pipes should be installed and explained the details. There are two technicians who came on the day of installation and they did a diligent job on drilling holes and connecting the pipes to make sure everything worked. This is totally worth the value. My neighbor saw their work and wanted to install one as well.

    MCS Water offers excellent service and is easy to schedule for water purification filter replacements and water softener system installations. This is the third unit I've replaced in 26 years. The Hydronex water softener system lasted about 10 to 15 years. The installer is highly professional and meticulous in their work.

    I had my LifeSource water system for over 12 years (I now live in a condo so couldn't bring with me…read moresadly) and absolutely loved it - the no filter changes, truly set-it-and-forget-it convenience was amazing! My parents recently purchased the Elite ScaleSolver PowerPac and absolutely love it. They've noticed significantly less buildup on their fixtures and appliances, and the water tastes amazing from every tap. My mom especially loves not having to go downstairs in the middle of the night if she forgets her water...she can simply drink straight from the tap! Best in class, and I love the peace of mind that it's NSF/IAPMO certified from top to bottom. Highly recommend!

    We live in Oxnard and have very very hard water. Before installing Lifesource, I had to wrap bags…read morewith vinegar and water in them around the and parts frequently to remove scale. I also had to take apart the faucets and get the gunk off the screens. I would say I had to do every couple of months now after years of Lifesource once a year and it's not nearly as bad as it ever was before. Service calls are wonderful people show up on time know what they're doing fix what they're there to fix and are incredibly friendly. The infrequent need to change the canisters is a real plus. While, you do have to plan for those expenses, they are long lasting. over time it was less that our collective monthly expenses, especially if the maintenance by hand that was required was considered. When we were evaluating the system. It sounded expensive until I did the math on what we were paying for soft water which my husband dislikes the feel of. The difference is immediately recognizable in showers for hair and skin is something far better than I was .expecting. The water coming out of the tap is great! We do have a reverse osmosis for ice. The grey water every two weeks is used for the lawn and outside plants, so no waste and no big delivery trucks on the street on a regular basis. Jonathan our rep is always available and we are very happy with Lifesource!

We also got the reverse osmoses system under the kitchen sink to further clean the water. This was such an easy and smooth process. We put in the order with Brad, scheduled an appointment for installation and our installer was Maurice. These guys know what they are doing and they made it very easy for us. The set the expectations and we didn't have to do anything. It took us about a couple hours where we couldn't use the water but then all we had to do is flush out the air from the new system. It's the third day now and everything is working great. WHY WE CHANGED: Just got tired of increasing monthly rates and having to open the garage for the techs to switch out the tanks. Also the Pro Water system does filter out more than the water softener we had.

Very friendly and explained everything he was doing. Love the system and everyone we have interacted with from the company has been great! I should add that when the system was originally installed Brad and I had a discussion about my vegetable garden and what would be the best solution so as not to get too much salt into that water as it would affect and potentially burn them. The installer was able to route our hose line so that it would continue to use unsoftened water and not affect my veggie garden. We are SO appreciative of this as we love eating our home grown tomatoes!!!

The workers came to the door and said that some machines needed to be replaced, and I was also very active in replacing them immediately. But recently, I called on June 30th and said that the filter needed to be updated, and I immediately agreed to replace it. They came to change the filter on July 1st the next day. After replacing the filter, the worker said that if there was a problem, I would contact them. I said yes. But last night, on August 6th, I found that the bottom of the pool was leaking and the water flowed out of the cabinet. When I checked, I found that a tube of the filter was slowly dripping out little by little. I contacted them and sent them video messages, but they didn't reply to messages and calls. I called them again the next day, and a Chinese woman answered the phone. She said that there was a fee for door-to-door maintenance. I said that it was because your workers did not install it after changing the filter water, and the water was a little flow. If it didn't flow outside, it would not be found. She said it's been a month, because it didn't happen before, and they didn't tell me that there was a deadline. This Chinese woman's attitude is very unfriendly, saying that the machine is old and needs to be replaced with a new one. But the worker didn't say that he needed to replace it. Every time I replaced the filter, the worker would tell me that some of them needed to be replaced, but he didn't say it this time. Now if there is a problem, I will replace it with a new one. And this is because the workers didn't install it well when replacing the filter, so it started to drip. Then she told me that she was driving and it was inconvenient to talk. It's inconvenient to answer the phone. Why didn't you say it at the beginning? I'm waiting for their follow-up now. I'll update...

Brandon came to the house and designed a system that would work with our plumbing situation. Unlike others who came by, he recognized a potential issue and offered a reasonable solution. He did not try to upsell us (again, unlike others). They use Clack Systems, so there is no lock-in to a particular system. Maintenance is minimal (add "salt" every so often). Brandon and his assistant showed up for installation as planned. With minimal fuss, the unit was installed within a couple of hours. We went about 90 minutes without water. Once the unit started functioning, the difference was immediately noticeable. Service, price, and performance are why you should choose Pure Water Filtration. We could not be happier.

The filters hadn't been changed since 2021, and the tank had completely lost pressure.

Richard and Greg came out and immediately offered to swap the tank just to see if it would salvage the old unit. When we realized the GE system wasn't worth sinking money into, we decided to upgrade and had Richard install one of his own systems. The installation was unbelievably fast, clean, and seamless. Beyond the quick service, not only are Richard and Greg incredibly knowledgeable, but they are also super nice and funny. We had a lot of laughs while learning more about drinking water and getting thoroughly educated on the new unit. We even opted to add an alkaline filter, and the difference is night and day. Now we have incredible, crisp-tasting water running straight to both our sink and our fridge, and we love it. Their pricing was exceptionally fair.
