Process could not have gone any smoother. Everyone we worked with was friendly, professional, and knowledgeable. Thanks, McCowin Water!

From Stacy to Brian to Matthew, what an amazing service! They had all such bright and friendly personalities. They make you feel like you're part of the family. Brian came over to our house to do the water test and asked a couple questions about what we wanted for our filtration system. Then he went on to suggest a couple systems and the pros and cons of each. After answering our questions, he gave us a card and we said we'll let him know our decisions. I called Brian the next day to say we'd like to install the system and he set it up quickly and easily. Matthew came a few days later and installed it quickly and correctly! A few days after Matthew had installed the under-the-sink filtration, Brian texted me to follow up. read more

What a great job! On time and worked hard! I'm really pleased with the water softener. Do doubt I'd highly recommend !

Loved that they were so quick to respond - especially with everything going on! We had a leak with our water filtration system and on a Friday evening they made it work. When Matthew arrived, he was professional and courteous! Answered all my questions and provided an estimate. No pressure and genuinely interested in helping in whatever direction we wanted to take! What a great guy!!! Then Brian (the owner) also stopped by. He wanted to make sure we understood what a great purchase we had made - even though we didn't buy it from them - over 15 years ago. Felt the team at McCowin went above and beyond! Thank you guys! Highly recommended!! read more

McCowin Water has great customer service and honest pricing. They offered to come to my home and test my water for free. They were very informative regarding the standard of water in my home and answered all my questions. I was able to choose the system that best fit my needs. They were also quick and efficient with the installation. I am very happy with my Hague Water System. read more

Brian McCowin and his team have consistently provided top quality service from the initial quote through every periodic check on the system. When he says, "Water quality won't be your problem anymore, it will be mine," he means it. Unmatched customer service that is both attentive and empathetic. read more

I have a Hague Watermax system that was installed in a home I recently purchased. The local company that services my area is no longer in business so I looked for an authorized provider on Hagues website. McCowin Water was the closest but was 90 miles away so not really practical to get them to service my system. I called them to explain what was happening and Dava put me in touch with their technician who walked me through the troubleshooting. I had the parts needed within a few days and my system is back to normal. This is customer service at its best. They now have a lifelong customer. I would highly recommend them to anyone that is looking for a honest company to deal with. read more

Super friendly and easy to work with! I had a whole house water softener system installed as well as a reverse osmosis in the kitchen for drinking. The installation was quick and I felt comfortable having the guys in my home. Would highly recommend McCowin Water! read more

We just had a soft water whole house system installed by this formidable company. We received a quick response time and a very knowledgeable salesperson in Scot. I would recommend everyone who is thinking about installing a whole house water system to call these guys. read more

When I went looking for a water system for my house, I had a serious problem. My daughter had been feeling ill and tests revealed that she had a high content of metals in her blood that a been leaching from the pipes that brought water to my house. McCowin Enterprises helped me solve that problem. I needed a guy that could fix the problem with an excellent water filtration system, and I was not looking for just any plumber that would push a system that they happened to have on the shelf. After extensive research, I came across the one guy that I thought was a true water expert and that was Brian McCowin at McCowin Enterprises. The three things that I look for in an expert is: I liked family-owned businesses, I want somebody who has been in the business a long time and finally who is not just pushing one particular kind of system. I found all of those things with this guy. Brian's dad started the business and now Brian is deep into a second-generation of experience. Brian is a consultant. He has access to every water system that is manufactured. It took a ton of time, but he was patient. He guided us through the process of purchasing the system that was just right for us. He guided us through our options from the cheapest to the most expensive systems and helped us find just the system that now provides us with crystal clear water every day with the flick of a tap. read more

McCowin was really amazing. We got their information from our neighbour and contacted them immediately. We got water softener and reverse osmosis installed by them. Scott and his team was very easy to work with. The best thing I liked about them was they weren't pushy as some of the other companies that we talked to and gave us time to decide. Also their rates were reasonable and very competitive. Scott responds immediately in case of any queries. We really appreciate their service. read more

We had the best experience with McCowin Water! Scot was so wonderful to work with, explained our options well, and was patient with us finalizing what we wanted! We love our new water system so much and love that our family has clean water now, it's made such a difference! Even our coffee tastes better and our ice cubes are so clear! Go for the top system, we've had no challenges removing soap which we were worried about and can use much less product. Honestly couldn't recommend them enough! read more

I moved to my new home last week and I was looking for drinking water filtration. I called several companies and McCowin responded professionally and promptly. I worked with Scott and he tailored a program perfectly to suit my needs. Matthew, the person who did the actual installation, was very courteous and professional. Then came the follow-up regarding the service, which I really appreciate. This is a first-class company starting from the top. I highly recommend them and you will feel the same way once you call a few other companies. 5 STARS! read more

Great service , top notch equipment , ask for Scot , he is super knowledgeable and listens to what you need

We have used McCowin Enterprises for several years now, at home and work. When we moved into a new condo, Brian made it super easy for us to take the equipment to our new place. He came out, removed and replaced the old system in the original apartment, and then re-installed in our new home with no effort on our part. It makes me feel comforted to know that the kids have clean drinking water at home, and that I have clean water to cook with at night. I would definitely recommend this company. read more

Scot is an amazing sales person, who is very honest & upfront about the pros and cons of each system. Instead of bad mouting his competitors when asked to draw comparisons, Scot emphasized the value that McCowin brings to the table -- their personalized approach amongst others. Installation was handled directly by Brian McCowin, who thoroughly explained and answered all of our questions. I've been happy with the water system thus far! read more

Moved into a new place and was tired of buying bottled water. I called up McCowin Water and they were professional from beginning to end. Quick turnaround from first contact to install (3 days), and Matthew did a great job on the install. read more

Outstanding job! Scott and Matthew are truly professionals! Everything went smooth and we highly recommend this company!

If you want to work with a company that is genuinely passionate about good clean water for you and your family, it's a no brainer than to go with McCowin Water. From my first email with them, to their amazing sales rep Scot, and installer, to even the owner coming out to meet with us, you really feel like you're now a part of their family. I had a couple other water filtration companies come out for consultation, but I just felt like a potential customer, and not a person. We highly recommend McCowin Water, and if you don't believe us, trust our dog! She is drinking more water than she ever has before, and we believe it's because she enjoys the taste of our alkaline filtered water! read more

When considering a water filtration system, I met with several companies - it's a big investment. Brian's in-depth knowledge of the various options, patience with discussing the products and genuine interest in learning about my needs in order to choose the right system for me were evident. He was creative and thorough re: solving a challenge that I had regarding the plumbing. Brian was responsive when I had questions and personally saw the process through from start to finish. It's important to note that because McCowin is a well-established family business, you get personal attention at a level that none of the big companies offered - each of the others were just unimpressive sales pitches. I am very pleased with my water filtration system - and will definitely recommend McCowin Water to others. read more

I love Brian and my in house water purification system!! He is pleasant and professional to have in your home. The water tastes great and I feel good about using it for cooking and drinking. When I needed new filters, he sent them right away and talked my husband through how to install them, which was easy. We are moving to a new house and he is going to come re-install. Thank you to Brian and his water purifying team!! read more

I started working with Brian 6 years ago. I need high quality water for the businesses I have worked at. I've tried bottled water, cheap filters, etc. etc... They can be a pain to continually keep up with and aren't always reliable as to continual quality. I've had a big difference with Brian. The set up is clean looking. Easy to use and any maintenance needed is done within 24 hrs usually. The same with the filters. My clients need excellent water and I can make it a reality with Brian's help. read more

I wish more companies worked this way! Great service from start to finish. The installation went smoothly and no mess was left behind. And the water tastes great too! read more

We have installed a whole house water filtration system through McCowin Water. You may think it's expensive, but it actually saves money and effort as you no longer need to buy bottled water. AND you NEVER need to use your squeegee on your shower door as soft water does not create water stains! We are 100% satisfied!! Brian and Dava, the owners of this business are the nicest and most reliable people that you can always count on their after-service. read more

I just got a whole-house water filtration/softening/reverse osmosis system installed in my new home. Two installers arrived at my house promptly and explained exactly what they were going to do. After completing the job at the promised completion time, they provided an in-depth explanation of the system. The installers were very friendly and pleasant to deal with. The installation was done neatly and professionally and they cleaned up afterwards. The sales manager, Scott, followed up after the installation to ensure I was satisfied. The fact that the company is local gives me a piece of mind that I can call on them in an emergency and that they will respond quickly. I'm a satisfied customer and would highly recommend this company to anyone wanting ultra clean water. read more

I had a Kenmore water softer that worked like a champ for over 23 years without fail. Once it gave up the ghost I was at a loss on how to "fix" it or obtain a suitable replacement. Along came Brian with the most perfect filtration system. I was able to choose the equipment that fit my budget and was pleasantly surprised at how fast and efficiently my issue was addressed! Brian was a pleasure to work with and was very understanding and patient with me...a non-technical person! The system is performing flawlessly and I couldn't be any happier!! Brian, his team, and everyone in the back office were a true pleasure to work with. If you are thinking of replacing or upgrading your system, get a bid from Brian. You won't be disappointed! read more

Our family has been a customer of McCowin Water for over 5 years. Brian installed 2 new water purification systems in our home and has been maintaining them over that entire period. They have performed flawlessly and we couldn't be happier with the service we receive from the entire McCowin water team. Brian has also serviced our water softener because the company that sold it to us originally is no longer in business. The model we purchased happens to be a model that has recurring issues. Brian has been been able to resolve the issues and get our unit up and running every single time, which has prevented us from the cost of a complete replacement. Most recently Brian returned my call promptly and went out his way to help me get my problem solved. Thank you to Brian and the McCowin Water team for good, old fashioned customer service! read more

Brian and his company did a whole house soft water system and under the kitchen sink drinking water system for us. He provided us with a lot of guidance on the different systems available and took something that is quite complex and made it understandable and intuitive. We love having clean glass and fixtures by not having hard water anymore! Even more, we love knowing that we are consuming the best water possible, especially in an area where the water is known for having a lot of unwanted "stuff" in it. Brian has come to service our drinking water filter and to assess any issues with our whole house system and has been a lifesaver. You've never seen someone so passionate about clean water as Brian McCowin! Thanks for everything Brian. read more

We recently bought a house and were lucky to have the water softener system which already had been installed. Later, we felt even much happier when we found out that Brian did the job! He educated us about the system, and answered all and every question that we had in a very friendly and professional manner. We were so comfortable working with him and decided to install the filter system for drinking water as well. He did an excellent job from the installation, educating and customer service. we would definitely recommend him to all friends and family if they need the water system. He is great... Thank you Brian for your superb customer service ! read more

I purchased a home purification system and alkalizing Reverse Osmosis machine for our household and for those of my two (adult) children who live nearby. We are all so happy with the actual machines and what they do (water tastes fabulous and clothes - and bodies! - are so much cleaner with so much less soap!) but the real boon is to have bought these systems through McCowin Water. What a wonderful company! Expert advice as to which units would best suit our needs, expert installation, perfect coordination of services. I truly feel our 3 families have made a friend who has our health and maintenance of our machines listed as a high priority. We couldn't be happier. Mary Robinson, Newport Beach read more

I was extremely satisfied will McCowin water system The Hegge is remarkable I have had for a year and it has consumed less than 1.5 bags of salt, to think how much my 17 year Culligan system wasted down the drain is just sad at 8.00 a bag! Thank you Bill for offering the best. read more

I am so happy I used McCowin Water for my whole home softening system! Brian was so easy to work with, answered all our questions and made this whole process so easy!
