    Was researching for months to find the best and most cost efficient soft water system. My coworker…read moretold me about this place so I called to request a quote. The lady that answered said she would forward my info to an Oscar. Oscar called me about an hour later and went over the entire system and the cost. His price was about $500-$1000 cheaper than local competitors. With good pricing and probably the best yelp reviews I decided to go with him. Installation was about a week later. The installer came around 11am and took about 8 hours to install the entire system. His install time too longer than originally quoted but I'm glad he took his time and didn't miss any steps. When it was all done he educated me on the entire system. It's pretty much a set it and forget it system except for maintaining certain salt levels. Within days I felt the difference in my skin. It wasn't as dry as before and the water really did feel soft. Highly recommend them!!

    The water quality has significantly worsened in just over half a year. When I contacted this place…read moreabout the issue, they only performed a basic water softener test and then advised me to take my water somewhere else for a proper water quality test. 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.

They only serviced the entire house or their R/O b/f water cooler standard or deluxe model (if they had water coolers) had to be purchased, they didn't rent. If they rented the monthly and install rate for 1 room was insanely high. Then I called CWS, talked to Phil, friendly helpful guy. Gave me unreal affordable quotes. I had to repeat back to be sure. They had various R/o b/f water cooler models. Standup unit or counter. Set a quick install date, Phil came and answered all my questions, showed me around the R/O b/f water cooler, the filters were inside the cooler. Who knew? Didn't have to go under the sink. The landlord wouldn't allow the R/O faucet install. Everything was great. Phil cleaned up. Made sure his install was fine even though he had another big job in south OC yet to drive to after my job. I was in IE. I highly recommend CWS to those who want filter clean water for just their kitchen fellow Yelpers. My cooler has 3 settings. Hot, cold, regular. If you want a Rental standup unit ask for a 'new' one. They'll know what you're talking about. My roommate will especially use the regular temp setting for her sunroom full of plants. I'm sure they'll (plants) thrive & be happy as I will. Call (CWS) them today. They're very friendly and courteous.

The water system I got 3 years ago from them had warranty so they stated they would come out and replace everything & add a resin filter. Once they came, they started to clean out all the faucets/shower heads since these little resin beads were stuck inside, cleaned the toilet tanks, checked my washing machine/ fridge water lines and even offered to assist changing out all the kitchen/bathroom valves (got the water valves via Home Depot myself). In addition, they flushed out my hot water tank as well. Now my house has 4 bathrooms, several sinks and faucets so a lot of this took some time but I never heard them complain and they went straight to work. They even replaced my drinking water filters. This company is A++ Now the water is back in my house and coming out even stronger. Thank you Tony, Andy and your team for all your hard work. Side note: I called a plumber before Crystal Clear Water and he said it was the PRV valve issue.. Changed the PRV valve and it wasn't even the problem so money was wasted there... so CALL CRYSTAL CLEAR WATER FIRST!!

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.

    I ended up choosing Pro Water Solutions for a whole-house water softener system and reverse…read moreosmosis, and I couldn't be happier with the experience. From the very first phone call, Brad was responsive and promptly returned my call. 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.

    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!

    After over 10 years with them I decided to research and look around for other options as price…read moredifference between Lifesource and EVERYONE else was significant. I started questioning because few years back, I was quoted over $4k for a water softener system that is not much different from what you can find elsewhere....then finally came the end of the tank cycle (approximately 10 yrs) and the quote to change it came close to $10k. Asked for a discount (which it was provided) but the final price still came above compared to a new system from other companies (installation included). My recommendation to everyone that is shopping for a whole water system is to do your own research and talk to at least other 2 to 3 companies within the industry. On the other hand EVERY single installer that came to perform any work was impeccable and we had a great experience with them.
