    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.

He took the time to explain everything clearly, gave me all the information I needed, and answered every question I had without making the process feel rushed or pressured. I spent a good amount of time researching different water softener systems because I wanted to make sure I was getting the best system for my money. After comparing several options, I decided to go with Diamond Pure, and I'm really glad I did. The installation process was smooth, quick, and very professional. The technician showed up on time, worked efficiently, and made sure everything was installed correctly. He also walked me through how the system works and answered all my questions so I would know what to do if anything ever came up. What I really like is how simple and easy the system is to understand and maintain. Overall, the entire experience from getting information, to purchasing, to installation was excellent. I highly recommend Diamond Pure to anyone looking for a reliable water softener system and great customer service.

Water seems soft but it doeant seem to remove any other toxic elements no more or does less This was especially disappointing because they advertise that these tanks should last 5 to 10 years. Based on my experience, the performance declined much sooner than expected, and I did not feel like the issue was taken seriously or properly evaluated.

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.

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.

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!
