    Water softener and water conditioner (they have more specialized names that I can't remember)
    Cary C.

    Although they are very busy and you may need to schedule out about 2 weeks+ before they can help install a system for you, it's worth the wait. I had our water softener system installed along with the water conditioner and a reverse osmosis drinking water system that has remineralization(important). The three brothers did an amazing job. A dominant competitor in SGV will use Puronics system which after some research, I would highly discourage. CWS uses Pentair/Fleck which are amongst top tier. Their pricing was actually lower then what the dominant competitor used for a higher quality system and work done!

    We had our water softener and conditioner system installed by Phil and his team. Phil was very responsive, professional, and knowledgeable. He took his time to explain how the system works and answered all of our questions. He did not try to upswell us on anything and was very honest, which I appreciated. The team wore masks during COVID-19, and were very safe and professional. After having our system for 3 weeks now, I can see a complete difference in our water quality- from the drinking water filtered through our fridge, to our clothes, skin, and hair. I am loving it! I would recommend CWS, Phil and his team to everyone who asks!

    Phil and Mike installed a water softener/conditioner at my house this past weekend. They took their time to make sure everything was installed accurately, up to code, and cleaned up. Phil answered all of my questions with no hesitation and came back to ensure everything was in working order. Phil was extremely competitive and gave you the best price/performance deal that you can find. Phil and Mike are high caliber individuals, and I would recommend them over and over. The wife and I already notice a massive difference in our water. I wish we found Phil and Mike sooner.

    Clean, secure, and easy on the eyes.

    Phil is THE MAN! I wish more businesses/vendors could be like these guys! As a first-time homeowner i knew i wanted a water softener for my newly renovated home but was frustrated and lost in my search for an installer - especially since I needed one installed on the exterior of my home. I called plumbers, handymen, and "Big Softener" companies like Culligan. But they were all so expensive (marked up) or untrustworthy in their practices. I was at the end of my rope until i found CWS on Yelp. Enter Phil: friendly, informative, no BS, straight-to-the-point, and TRANSPARENT. From the get-go he was extremely upfront about the equipment, prices, and what to expect on the low to high end - and never tried to unnecessarily upsell me. One good byproduct of my endless search before CWS was that I gained a lot of knowledge about equipment and the "softener biz" and it was clear that Phil's quotes were extremely fair and reasonable. I was pleasantly surprised by the fact that his prices were not much more than just buying the equipment on my own (except with CWS I get a professional installation). Installation day was smooth as softened water - Phil's crew was friendly, quick, organized, and always communicative. One last thing: these guys are young and knowledgeable. I mention that because they are not like the "salty" old boomers who see uninformed customers as easy targets. The CWS guys have a "disrupter" vibe (like in the tech industry) who will hopefully take Big Softener down! Forget Culligan, Lifesource, etc. who all try to "hook" you with constant maintenance calls. CWS is who you're looking for if you want savvy, easy to talk to, fair prices, and high quality!

    I had both water softner and water filtration system installed by Phil about 2 months ago. I waited until now to make sure everything is in working order before I write up. I was really impressed with his workmanship and professionalism. He took time to complete the job, clean up after done. One time I saw too much water in brine tank. I texted him and within 30min he showed at my door to check it out. It turned out there was nothing wrong. I highly recommend him if you ever want to put a new system in your house.

    New faucet that matches perfectly to our sink.

    Phil and Mike were very helpful. The install was done very professionally and we are happy to use our new alkaline water system. Great family owned business and we would highly recommend them if living in the area.

    Phil and team did a great job at setting up our whole house water system along with purified alkaline drinking water. Very knowledgeable staff and very time efficient with their work. Phil will take the time if needed to help you understand what it is that you're getting so don't be shy to ask question as it is an investment for yourself.

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.

When he came out to assess my home and provide an estimate, he took the time to thoroughly educate me on my water quality and the available solutions. I left that visit feeling much more informed and confident in my decision-making. After comparing a couple of other quotes, I decided to go with Pro Water Solutions--and I'm glad I did. Brad's knowledge really stood out. He tested my water, along with the bottled and filtered water we had been using, and the results were honestly shocking. Installation was scheduled and completed in less than a week after I gave the go-ahead. Daniel, the installer, was excellent--professional, detail-oriented, and made sure everything fit perfectly. He also walked me through the entire system and made sure I understood how to use it. Overall, a smooth, professional experience from start to finish. Highly recommend.

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!

I also had to take apart the faucets and get the gunk off the screens.

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!

That company came out, didn't provide any literature and verbally explained what they offered and quoted some ridiculously high prices. Then I was driving home one day and saw a service truck for MCS in my neighborhood that had graphics on it that said they installed Puronics systems. I spoke to that technician and he came over to look at my existing worn out system. He had literature explaining all their offerings and quoted prices that were much lower than the other authorized installer had offered. He gave me the quote on a Friday and three days later on Monday, they finished the installation in about 3 hours. The completed installation looked very professional. In setting up and testing the system, the installer (Jun) fine tuned the settings for the hardness of the incoming city water, the number of people in the household, the system regeneration timing (# of days), etc. while continuing to check the outgoing Puronics water for the correct softness (with a chemical test) after each adjustment. He then explained to me the functions and operation of the control panel. In summary, I'm very satisfied with MCS Water Technology for their pricing, installation and quality of technicians. My lesson learned is to check if there are other authorized installers in neighboring areas for an item you're shopping for. In my case, I found a gem of a company in MCS that was just a few miles away in Rowland Heights.
