New water softener system
Joe C.

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.

Did a good job
Christine C.

We had a great experience getting our water softener installed. The service was fast, professional, and everything was explained clearly. Our water feels so much better already and the whole process was easy from start to finish.

Terminator
Jane ..

We recently installed the Terminator water softener with a tankless RO system from MCS Water, and the whole experience has been excellent. From the start, Michelle was wonderful to work with--she was patient, knowledgeable, and very clear in explaining the options. She helped us choose the Terminator system with NASA-inspired MicroSilver Bacteriostasis™ technology, which gave us confidence we were investing in one of the best systems available. When it came to installation, Master Wong did an outstanding job. His workmanship was precise, professional, and very efficient. He also took the time to explain how everything works and left the setup neat and clean. I highly recommend MCS Water, Michelle, and Master Wong to anyone considering a water softener or RO system. The combination of excellent customer service, high-quality products, and professional installation is hard to beat.

Clear communication, fast, nice to my dad. Good prices and local!!!! Only take a couple hrs to install my filter and I love it

I got the water softener installed today by MCS water technology. The two technicians did a great job. They also explained well on the machine and maintenance. They also cleaned up the garage afterwards. Overall good experience and would recommend.

Good service and excellent quality jobs. I have been with them more than 20 years. Will still go with them whenever I need.

water softner

Had a great experience installing our water softner system. The team was professional, punctual, and explained everything clearly. Installation was clean and efficient, and the water quality difference is noticeable right away. Highly recommend their service.

Puronics Terminator soft water system.

Walked into the San Gabriel MCS showroom and was help by Tinny. She is very knowledgeable and was able to help us with what we were looking for. We decided to purchase a soft water system from MCS. The process was smooth. Tinny contacted me to confirm installation date and time. Everything was installed on date that was promised. Highly recommend MCS for your soft water system needs.

Water Softener
Eric S.

The MCS team is informative, professional and credible with a solid reputation. After shopping around for a while-house water softener system, I went with MCS for the install. Michelle, the rep, provided competitive pricing and didn't try to oversell or pressure me into other solutions, which I appreciated. Ultimately, I chose them because they have been around since the 90's, served my dad since, and have a good reputation in SGV. The installers were patient and knew what they were doing, and stayed for over 8 hours to get the job done (my install was particularly complicated, and cost extra but reasonable for the work entailed). Would recommend them to others interested in a water filtration system.

MCS did a great job on helping my house to add a water filter system, they were quick and efficient and offered professional experience.

Had water softener installed. The installation was easy and fast. The technician was easy and installation was fast . Great service from the company.

Jack C.

Just got a water softener from MCS installed -- super smooth process and it works great! My water feels softer, no more scale on faucets, and even laundry feels fresher.Big thanks to Tinny for being so helpful. Highly recommend MCS if you want better water at home!

Got new water machine.  Everything so far so good.

See all

I begin searching for the home best water filter companies because several homes in our neighbor…read morebegan having pin-hole copper tubing leaks - with the accompanying water damage & expenses to completely fix the pipe & patch up the holes made while locating the leak. One of the companies I called was Diamond Pure Water and I spoke with Mike. He mentioned that chloramine is the corrosive chemical in municipal water that eats through thin copper pipes (type-M) & that a catalytic carbon filter system would remove all chloramines. I also called a number of other companies & it was clear they weren't interested in spending the time texting & on the phone with me that Mike did. He set me up with a great dual catalytic carbon filter (to completely remove chloramines) & a soft water filter ( to treat hard water & remove calcium & magnesium). The system looks good & fits perfectly in a corner of our garage. Diamond Pure Water was also the lowest estimate of the 3 that I got.

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.

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.

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.

I had done some research ahead of time and knew basically what I needed. Chuck came by and didn't try to sell us anything more than we needed. He was quick with testing the water, reviewing the space, and providing a quote. The quote was competitive and he answered all my questions with everything I was looking to understand. During the install day, the team showed a bit late but still made it. They got to work and did a very clean job. No mess and everything is neatly installed. All piping works for my space and doesn't require me to sacrifice my garage. The crew was professional and even made a wiring change when I requested. I couldn't believe they managed to get the equipment in the small space beside my existing shelves. I previously had an under the skin RO but decided to upgrade since mine was 10 years old. The new filtered water is great, not much better than the previous RO though. It does take significantly less space under the sink. The softened water is great too. I wouldn't drink it, it has a briny taste, but I've noticed significant improvements to my fixtures I'm trying to protect plus my hair feels so much nicer. I'm happy with the purchase and experience.

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.

The communication was very clear. I received text updates regarding time of arrival. Tony text me prior to coming and I sent him a picture of the system. I'm assuming he brought parts along based on this because he was able to replace a big part on the spot. Tony was very knowledgeable. He could tell what was potentially wrong in my house just by looking at the system. He even fixed my sink upstairs that no longer had water flow. All in all, the whole service took about 2 hours. He was able to reset my water softener, replace a part, and fix my sink. He even gave me some water test strips. Spending $200 for a 5-year maintenance is completely worth it. Now I don't need to think about it again until 2031!
