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, Scot, 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.

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 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!

Linda W – Mission Viejo

We needed to replace a reverse osmosis water system. I went to a local water store in San Clemente. They did not call me back and there was poor service. I put a request in the internet for a quote on a new system and Brian McCowin responded right away. He came to my home and showed us several options to replace our old system. He installed it next day. He charges a fair price, and he does a great job. Fast and efficient. he even adjusted our water softener system. I highly recommend him for your water systems and plumbing.

McCowin Water is an exceptional provider of water solutions and a great company to do business with. We have used McCowin Water for 15 years and continue to be impressed and highly satisfied with their professionalism, strong ethics, product value and expertise in this specialized field.
The ownership and the employee staff are conscientious, knowledgeable and customer oriented.

Terry & Denise S – Huntington Beach

We have been doing business with Brian since we moved to southern California 19 years ago.  Our first water purification home system lasted 18 years and performed above our expectations.  We replaced it last year and Brain was our first choice.  Our new system incorporates more advanced technologies (to offset the less pure water we now get from the city line), and we are very pleased with its performance.  The quality of Brian’s systems is very high, and the price is very competitive.

Rick V – Huntington Beach

Brian and the entire McCowin Water team have been extremely professional, caring, and courteous to my family for over five years now. The water filtration system you utilize is a very important decision for any family, and we are very pleased that we chose McCowin Water over all of the other companies. The customer service has been very responsive and outstanding at all times. They are always timely with their follow up and maintenance program to ensure we always have the safest and cleanest drinking water possible.

Clay S – Mission Viejo

Brian is a pleasure to work with, he is honest, extremely knowledgeable about water and the various systems to treat it. He is positive and always follows through! Brian installed systems for my family many years ago, years later, as an interior designer, I am confident to recommend McCowin Water to my clients for their homes!

Chelsea S – Los Angeles

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 R – Newport Beach

I was extremely satisfied will McCowin water system The Hague 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 Brian for offering the best.

Art L – Newport Coast

Great company!!! I’ve been doing business with them for years. I highly recommend them.

Michelle E – Orange

McCowin Water has serviced our home for over 10 years.  Brian has always given us “Best-in-Class” service and had our best interest in mind.  He is very knowledgeable, friendly, and professional.  We highly recommend McCowin Water for your water servicing needs.  You’ll be glad you did!

Greg E – Trabuco Canyon

I love this guy. He’s been handling my water filtration at home and work for years. Our office just moved last month and he came right out and de-installed our filtered water and took it out and sanitized it all and then re-installed it at our new location right away.  I forgot to tell him the Landlord wanted copper piping.  He installed poly (which is better in my opinion) and I had to call him to come back out because I had forgotten to check and the Landlord does insist on copper.  He came right back out.  Always cheerful and businesslike. Use this guy!!!

I love that McCowin Water reminds us when it is time to change out the filters.  They explained how we could do it on our own, or have them come out to do the maintenance for us.  Personally, I’m happy to have them take care of it.
We looked at other companies before selecting McCowin Water.  Their science made sense, where the other companies couldn’t really back up the science behind their process.  This is a solid company, providing outstanding service!

I used them for a whole house water system 3 years ago and they have followed up every year to maintain the system, Great Job!
I recently added a drinking system and used them again and another great job.

Michael R – San Clemente

We acquired a custom Commercial Whole Home System with GAC (granular activated carbon).  We also got the reverse osmosis system under our kitchen sink for our drinking water.  Brian was very hands on in educating us on our options and customizing our preferences.  We love the feel of the water, which we would describe as “satiny” versus the super slick feeling that other soft water systems can give you.  We love how our skin feels, how sparkly our dishes are out of the dishwasher and how soft our laundry turns out.
Our system removes the hardness (hard minerals) causing our water to be “soft” and also removes chemicals and other toxic additives, such as Chlorine and Chloramines, protecting not only your pipes, appliances and your home and our family’s health too. Our system uses potassium which means the water is healthy to use on plants and landscaping.  I can attest that our plants seem to love it too!  We highly recommend Brian’s company.  The installation was smooth and efficient and it’s very low maintenance.  We even got an email reminder for our annual follow up service call which was handled very well.

Rita S – Irvine

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!

Sue M – Mission Viejo

I purchased a water conditioner from McCowin in 2000 and I have to say that I am very happy with the product and the service.  I even brought my unit with me when I moved. I absolutely love the clean water and the savings.

Brian was excellent.  My wife and I had recently moved into our home and fortunately, Brian had been to our house with the prior owners.  He knew what our reverse osmosis system needed and repaired it with ease.  We now have great tasting water.  We also had a tankless water heater and a new water softener system placed and Brain recommended another provider for that service.  He came and monitored that installation and made sure that all was in working order before he left.  He is always friendly and easy to work with.  I would recommend McCowin without hesitation.

Craig R – Huntington Beach

I am so happy with this company.
They claim to create water snobs and I have to admit, I’ve become one! The pure water created by their filtering system tastes so good and I know that it is safe for my family. Pricing was better than competitive and they are very knowledgeable and honest.

Shaun H – Fullerton

My daughter kept telling me I should get a drinking water system like the one she has at her kitchen sink from McCowin Water, But I was fine buying cases of bottled water whenever I went to the grocery store.  I didn’t really mind picking up the cases of water, I would just carry them on my walker from the car to my house. Then I had some health problems involving my back and I was told that I couldn’t lift anything heavy so now my daughters had to get water for me.  That’s when I decided to go ahead and get a reverse osmosis drinking water system from McCowin Water.
I am so happy I did! I can’t believe how much better this water tastes. And now I only have to go to my kitchen sink to get it whenever I want.
I like that they are a family owned company. I should have done this a long time ago.

Patsy B – Seal Beach

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.

Sam S – Lake Forest

Our reverse osmosis unit in our home and business from Brian at McCowin Enterprise gives us great tasting water. We have been using both of these now for a few years and have never had a problem. New filters are delivered without having to call. We always take plenty of our water with us when we are on the road, because we are so use to good quality water.
The service is a great and everyone we have referred them to has been very happy with them and their products.

Ron D – Fullerton

We recently purchased the WaterMax system through McCowin.  While I can’t comment on how the system has changed our lives just yet, I can say that their customer service and professionalism has been great.  From the first contact with Tammy, the sales call with Scot to the installation with Matthew and Spencer – they were all very responsive, answered all our questions, explained the system, provided references and were a pleasure to work with.  I will post another review when we’ve lived with our new water system for a while and taste and feel the benefits…..can’t wait!

McCowin water has been wonderful to work with! Brian, in particular is always very responsive, timely and organized. He’s very knowledgable with the products they offer as well as water purity in general. We have a purified water system installed in our kitchen with the Insta-hot boiling water which comes in very handy almost everyday! We feel great knowing our family is drinking pure water without wasting plastic bottles or endangering babies/children with the choking hazards of plastic bottle caps. Thanks McCowin water for being a reliable vendor for us!

I had a Hague Watermax water softener and a reverse osmosis drinking water system installed by McCowin water on 07/30/2018. Brian McCowin came to my home and presented my options prior to making the decision to buy. He was very pleasant, patient and did not pressure me into buying. I felt comfortable doing business with McCowin Water because I feel the genuinely want to help their customers get great water and will be there in the future to help maintain your water system. They are a local family business that is based close to where I live in South Orange County. The work was done in a timely manner. I am very happy with the product I believe that I was given a fair price.

I was so tired of living with the terrible hard water here in OC California. I have been plagued with pinhole leaks in my Copper Pipes. I have had hard water stains on my plumbing fixtures. In the past I used to buy bottled water and was concerned about plastic leaching into the water from the bottles. Now I have drinking water that is better than bottled water in my opinion and can shower, wash dishes, and do my laundry with great soft water! Buying a water treatment system has greatly improved my quality of life! I highly recommend McCowin Water.

Brian and his team did a great job. They carry multiple filtration/RO systems from different brand, and Brian will explain to you their difference and find the best one for you. The installer did a fantastic job to finish everything in a tight time frame, and kept everything nice and clean.

The improvement in water hardness and quality is quite instant. I’ve been using the system for a week now and everything works well. I would definitely recommend McCowin Water to anyone!

I’ve been searching for a whole house water filtration system and requested quotes via Yelp. Brian responded via phone and advised me that I was out of their geographic service region but proceeded to assist me in understanding the industry and the different systems out there. He broke it down into plain English and was up front. He knew he wasn’t getting the business but helped me through the selection process answering any questions I had via email or phone. I wish I could’ve of done business with him because Brian has the integrity and the generosity with his time to help those in need. He has a passion for water treatment and lives and breathes this stuff. If you live in South OC and need water purification service, McCowin Water should be on your list of vendors to call.

Highly recommended water filter system! We have been experiencing it for one month. So far, everything is great: soft feelings from water, shiny surface inside water boiler (white layers of materials could be seen before), sweet drinking water, smooth skin after bathing, and so on. The other great thing is from the customer service experiences: quick response about any questions and problems, kind and courteous and easygoing Brian, effective installation and various follow ups. I will definitely introduce this company to more friends. However, a little reminder: make sure the main pipe to the filter system is separated from the irrigation system outside your house. We are suffering this headache: soft water goes out to water the greens. What a waste!

We love McCowin Water! Brian was very courteous and very funny when he installed out Water Filter. He explained everything to us in very non-technical terms and even discouraged us from trying to read the manual because it was too technical! Who does that? 🙂 Anyway, about the product, just as a warning, you’ll be spending in the 4-digit range, but it is worth it! My wife and I can taste difference, and we can bathe the difference too. When the water comes out of the sink, it almost feels like you are washing your hands in lotion. The water feels soft and you can clearly feel the difference taking a bath or shower. Also, we don’t need to use a lot of laundry detergent for laundry and we don’t have to use very much washing dishes either. Furthermore, it’s very easy to disable the filter if you have problems and go back to the old water if you need to do some type of service, which you shouldn’t have any at all. I highly recommend McCowin Water!

I had NO idea there was so many water filtration systems out there! I was so overwhelmed by other companies until Brian came to our house. He was amazing, patient, honest, and took the time I needed to fully understand what we had in our water and what systems would be good in our home. Our installer Vinnie was great. We were so excited to have clean water but didn’t realize the difference we’d feel, taste, and see. We have no more water spots on our glass YIPPEE. If you are looking for a water system and great company you have found it! Thank you Brian McCowin @ team!

We are highly satisfied with McCowin Water after installing their customized system for our home a few years ago. I remember when Brian first installed the system and we purposely put aside a pitcher of water from our regular tap and then after his system was up and running did a taste test against our new filtered water system. UNBELIEVABLE difference. So much better after the filtration process! We chose to do a whole house water filtration because our tankless water heater was creating big mineral deposits that were clogging up our aerators. I love that McCowin Water reminds us when it is time to change out the filters. They explained how we could do it on our own, or have them come out to do the maintenance for us.

“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. “

They were also quick and efficient with the installation. I am very happy with my Hague Water System.”

“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.”

We have been using the sink filtration system from McCowin Enterprises for about 4 years now and we would not go back to any other way of getting great drinking water! The taste is sooo good and the service is great! They will explain everything to you, and I also really like that they are not pushy sales people. I recommend them to our family and friends.

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.

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.

I did my research with several local water purification companies around Orange County and I was very impressed with McCowin Water and felt that Brian was not only knowledgeable about water purification systems but he was also a true master of his craft in this industry. He took his time to educate me on the different types of systems that were available and that each household has different needs and he won’t try to oversell you on what you don’t need. He was also one of the first companies to reach out to me through yelp before any other company. Through our interaction, I got the feeling that the company is very family oriented and that if you go with them, then they don’t consider you as just a customer but also as a family member as well. They were one of the top water purification companies that I can say that I would recommend to others. If you’re thinking about purchasing a home water system, you should definitely reach out to them and give them some consideration.

Brian and McCowin Water have been exceptional in all our interactions with them. We had them install a general water softening and filtration system in our house, and the service and results were impeccable. It makes a huge difference to us when dealing with someone who truly loves and cares about they do, and Brian is one of those people – he took us through all the available options, and made honest suggestions on what would best suit our needs, while speaking very knowledgeably about the field. Our water feels and tastes amazing now! We’re not only happy with the installation work, but we’ve had him back twice now to make sure the system is running properly and to replace any filters that were due. Brian is always a pleasure to talk to, and you can tell their business is built upon customer satisfaction and taking the long view – we know we’ll keep coming back to them, and refer others as well.

After literally months of research and talking to all the top rated Water guys on Yelp, I found Brian’s products to be the most price competitive for the quality you are going to get. There is soooo much hype out there and lot’s of guys trying to sell you slippery-slick snake-oil. Good clean water is just that: good clean water. If you’re reading this review then chances are water is important to you in some way. Then, do all your research, call all the other guys, and do yourself a favor and call Brian last. He’ll set you up with the best system for whatever you were going to pay the other guys. Brian is a second generation Water guy and has access to more choices than any other company I came across. Brian always answers my phone calls and can be reached via text. Here’s my favorite thing about McCowin Water… the service. A+ for service. 2 calls for minor check-up’s: the first call and Brian showed up the next day. The second call he was able to superhumanly stop by within 10 minutes and problem solved. Brian and his wife Dava are the best in the water biz, hands down. Thank you Brian for giving us water that is sooooooooooo good. Our entire house has water that is zero chlorine and zero chloramine. Wow! No other system out there can promise you that in writing with a warranty!!!

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!!

When we moved into our home about 6 years ago we discovered it had a very complex and somewhat outdated water system. We had Brian come out to service it, explain it, and update it. He did a great job – he obviously knows his stuff – and we now have him over yearly to do routine maintenance (but he did show us how to do it ourselves, if we wanted to go that route). Brian is always punctual and he’s a super nice guy to boot. I would highly recommend him!

I love this water! I have it in my home and office and it is great! Brian and McCowin Water is amazing and they truly cared about getting me the product that I needed. I got a great water system that fit all my needs at a good price. Honestly, he is so easy to work with and he will tell you straight up, I love that about him.

Brian is an amazing person. I actually had compared several companies two years ago, and went with McCowin Enterprises for our filter and salt water system. Brian was not pushy, and he patiently provided me with articles and other helpful information to help me make a decision that was right for our family. I recommended him to at least four other friends/family, who also ended up using him. About a month ago, Brian calls me, from out of the blue, to say thank you for all the referrals he has received. He also offered to put in an RO system for me, at no charge. Wow! Who does that?! I tried to dissuade him, and told him that I recommended him bc I was happy with him and their company, and I did not need any reciprocal action from them, but he insisted on doing something for me. (Again, he wasn’t pushy. He said he would love to put in the RO system, but if I didn’t want it, he would find a way to do something else nice for me.) Anyway, long story short, he did install the RO system. Our water was great before, but is even better now! I would whole heartedly recommend Brian and McCowin Enterprises.
