Don’t Replace Your System Until You Know What’s Really Wrong
Think Your System Just Needs to Be Plugged In? That’s the First Mistake.
Most water systems fail, not because they’re cheap…
but because they were never installed right to begin with.
Here’s what we see all the time:
⚠️ Leaks from poor connections
⚠️ Pressure issues from bad placement
⚠️ Systems underperforming, or breaking down years too early
That’s not on the system.
That’s on whoever installed it.
What Makes McCowin Different:
At McCowin Water, we don’t “plug it in and wish you luck.”
We design every install around your home’s plumbing, pressure, and water profile so it works the way it should… for as long as it should.
✅ Seamless integration
✅ Optimal placement
✅ Tested, calibrated, and explained, clearly and completely
You don’t have to chase techs.
You don’t have to guess.
You don’t have to worry.
What Homeowners Are Saying:
“The install was smooth and professional. McCowin Water explained everything thoroughly and made sure I understood the system’s features. They were respectful of my home and left everything spotless.”
– Mark S., Newport Beach
When You Choose McCowin, You’re Not Just Buying a System, You’re Buying Peace of Mind. Let’s check what you’ve got, or install it right the first time. Either way, we’ve got your back.

Think Your Water’s Fine? This Common Mistake Proves Most Homeowners Are Wrong
You Spent Thousands on a Water Softener... And It’s Quietly Failing Because No One Told You This...
Most homeowners think once their water softener is installed, it’s good to go.
But here’s the part no one tells you:
Without regular maintenance, that “set-it-and-forget-it” system becomes a silent liability.
❌ Filters clog and choke off performance
❌ Minerals build up and strain your system
❌ Salt or potassium runs low, making your softener useless
Over time, your system works harder, costs more, and eventually breaks down, way before it should.
At McCowin Water, we don’t disappear after install.
We keep your system running like it was day one, with zero guesswork on your part.
Here’s what our maintenance service includes:
✅ Scheduled Filter Replacements – to keep water quality consistently high
✅ Salt & Potassium Delivery – we handle the heavy lifting, literally

No mess. No downtime. No wondering if your system’s doing its job.
PROOF:
“We’ve had our system for over three years now, and McCowin Water has been amazing. From scheduled maintenance to answering our questions, their service is unmatched. We wouldn’t trust anyone else.”
– Lisa P., Laguna Beach

Posted onHenry NovellTrustindex verifies that the original source of the review is Google. Maaison does excellent work. I highly recommend. He is very experiences and could answer all my questions related to The Hague water softener and the RO water filtration system. Highly recommend Brian and his team of employees. He has low turnover which speaks volumes for a good operation.Posted onEthan BlairTrustindex verifies that the original source of the review is Google. No matter what you have installed or serviced, this company knows what they are doing. I’ve never know a company to have such intelligent and capable employees all around. From quotes, to scheduling, service and follow up you are in the most capable hands. We have been with McCowin water for 7 years and only encountered positive results. Employees are happy and love the company! It’s the coolest thing to witness. Thank you for being such a steady and loyal partner in keeping our water and home protected. You are family to us!Posted onTom PhillipsTrustindex verifies that the original source of the review is Google. Very friendly and professional technician. Great customer skills as well. He couldn't say enough nice things about the company. Answered all questions I had.Posted onMike MichinoTrustindex verifies that the original source of the review is Google. This is the most well run, professional, punctual, competent, and honest business I have ever encountered across any field. It definitely shows that it is a family run business that takes personal pride in its work, its employees, and its integrity. Every single service tech who has come out to our home has been the quintessential professional. All experts at what they do, meticulous, and complete in every detail. They do not cut any corners. I love tinkering with mechanical things and am very OCD when it comes to my water quality. I was especially pleased to discover them using the same and better “Hach” water testing equipment that I personally use, and making sure to perform all of the tests as part of their standard routine, with no prompting from me. What particularly left an impression on me was the visit from technician Maaison today. After thoroughly completing all of the annual checks, he courteously asked me multiple times if I had any questions. I could not think of any because he was already so thorough in all of his explanations and demonstrations. But then when he went to update the interface on my unit, he noticed me quip that I would have to consult the manual to learn how to do that myself. Maaison not only re-explained the procedure again, he actually jumbled the controls and allowed me to reprogram the interface myself to make sure that I could actually do it myself after he left. As I attempted to implement his teachings, Maaison continued to attentively pay attention and pointed out the mistakes that I made and corrected them in the kindest most respectful way possible. The employees of this company are not only great people, they are great teachers, and we all know what kind of person it takes to actually teach (I mean the good teachers, lol) and pass on knowledge. Kudos to McCowin Water, Inc! What an amazing company.Posted onJuliet WilliamsTrustindex verifies that the original source of the review is Google. Maaison was great and super helpful!
