    So after 5 years with Culligan, we switched to Pro Water's state of the art system to clean up the…read morewater coming into our home. 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.

    This was honestly one of the easiest and best purchases I've made. From the beginning, Mike was…read moreextremely helpful and professional. 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.

    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.

    Imagine being able to drink water straight from the tap, with no more hard water stains, less itchy…read moreskin, softer hair, better tasting coffee, and appliances that last longer. That is what we got with carbon filtration and water softening. If you live in Southern California, you know what I am talking about. I really wish we'd installed it years ago. If you own your home, investing in a good system can improve resale value. After a lot of research and discussions with several service providers, we went with Pure Water Filtration. 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.

    I must say that if I ever have any more soft water system problems that I will call pure water,…read morefiltration, and specifically ask for Brandon for my needs! I recently had a situation where the salt was not going down in my brine tank and the water didn't feel soft in the shower any longer. Brandon asked me for a couple pictures and description of the situation and then instead of charging me $150 fee to come out and fix it (which many might do)... He verbalized to me over text what amounted to a five minute fix. Just don't find people in this world today who are that kind anymore and I greatly appreciate Brandon and Pure Water Filtration for their kindness. There is no need for me to get competing offers anymore from Yelp... Pure Water Filtration is my one stop shop for my soft water system needs Do you won me over thank you!!!

He provided me with all the details of the water system that our city requested to pass inspection upon installation. His installation team is professional. They have the eye for the little installation details. I said this because of where my system had to be installed, and the team worked hard to make it happen. This morning, my inspection passed in flying colors. Edward was confident it would pass. We purchased the Premier Twin-Tank Non-Electric Softener, Premier Twin-Tank Non-Electric Chlorine/Chloramine Filter. There are only two of us in the household, and the product is sufficient enough for us. We couldn't be happier. It's a great system from a great company. As for value, I have said it all.

    I was running my hand through my hair this morning and thinking "whoa my hair feels so soft"…read more Thanks Kinetico! I've had three systems installed by them and the process is always great. They recently helped me take my reverse osmosis system with me from my old house to my new one when I moved. I love the peace of mind I feel when I'm refilling my kids water bottles before soccer practice. The whole house water softener system is something I've been planning and saving for. My new old house (built in 1958) needed two systems instead of one, which would have been out of my price range. But they worked with me to finally make it happen. Roman is a great technician and his installs are super tidy.
