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!

The 3 Changes
That Happen After Perfect Water Hits Your Pipes
The 3 Changes
That Happen After Perfect Water Hits Your Pipes

Chlorine & Chloramines Keep Working
Great for killing bacteria during transport. Still working on your copper plumbing when it reaches your faucet.
Bleachy smell. Skin irritation. Pipe corrosion.

Minerals Accumulate Over Time
Safe to drink every day. But calcium and magnesium build up in your water heater and appliances over months and years.
Scale buildup. Reduced efficiency.
Early appliance failure.

Pressure & Sediment Effects
Your city maintains consistent pressure. But your home’s plumbing has unique flow characteristics.
Iron, rust, and particulates stress fixtures and reduce appliance lifespan.
Your water department delivers quality.
Your pipes deliver the final experience.
But you’re paying for the damage… every month.

The Truth About Orange County Water
(That Nobody Talks About)
The Truth About Orange County Water
(That Nobody Talks About)
Most water companies aren’t bad at water treatment.
They’re bad at listening.
Their business model isn’t built around understanding your water, it’s built around moving inventory. And that single difference explains why so many Orange County homeowners end up with systems that don’t solve their actual problem.
At McCowin Water, everything starts with a free in-house water test in Orange County. We listen first, test your water in your home, and only then recommend solutions that match your real water conditions.
The Water Industry Is Product-Driven, Not Problem-Driven
Proudly offering free in-house water testing across Orange County including Irvine, Mission Viejo, Newport Beach, Huntington Beach, and surrounding areas.
Orange County Water Is Treated Well, Until It Reaches Your Home
Orange County Water Is Treated Well, Until It Reaches Your Home
Orange County has some of the best municipal water treatment systems in California. The water leaving the treatment plant is clean, regulated, and balanced to meet safety standards.
But that’s only the first part of the journey.
Before that water reaches your tap, it travels through:
- Miles of aging city pipelines
- Neighborhood distribution lines
- Your home’s internal plumbing system
By the time it reaches your faucet, it’s no longer the same water.
This is why a free in-house water test in Orange County is so important, it shows what actually arrives at your home, not what left the treatment plant.
Chlorine Protects the Water But Attacks Your Plumbing
Chlorine Protects the Water But Attacks Your Plumbing
Chlorine is added to city water for a good reason:
It keeps water safe as it travels long distances.
But once chlorine enters your home, it starts doing something else.
- It reacts with copper and metal pipes
- It dries out skin and hair
- It contributes to unpleasant taste and odor
Over time, this chemical interaction can weaken plumbing and reduce water quality, issues you won’t notice right away, but that build slowly.
A free in-house water test in Orange County can measure chlorine levels at your tap, not at the city source.
Minerals Are Safe to Drink But Not for Your Appliances
Minerals Are Safe to Drink
But Not for Your Appliances
Orange County water often contains hardness minerals like calcium and magnesium. They’re not dangerous to drink but they are destructive to appliances.
Over time, these minerals:
- Build up inside water heaters
- Reduce efficiency of dishwashers and washing machines
- Damage coffee machines, boilers, and fixtures
- Shorten appliance lifespan
Most homeowners only realize there’s a problem after expensive repairs or early replacements.
That’s why scheduling a free in-house water test in Orange County is so important. Testing your water early helps prevent long-term damage instead of reacting to costly breakdowns later.
Water Pressure Isn’t One-Size-Fits-All
Water Pressure Isn’t
One-Size-Fits-All
Here’s something most people never consider:
The pressure designed to serve an entire neighborhood might be perfect for your neighbor but too high for your home.
High water pressure can:
- Stress fixtures and valves
- Cause leaks behind walls
- Reduce appliance lifespan
- Increase plumbing repair costs
During a free in-housee water test in Orange County, pressure and plumbing characteristics can be checked alongside water quality, something a lab test alone can’t do.
The City’s Job Ends at the Meter, Ours Starts There
The City’s Job Ends at the
Meter, Ours Starts There
This is the part no one explains clearly.
The city is responsible for delivering water to your meter. Everything after that, the pipes, pressure, appliances, and fixtures is your responsibility.
You wouldn’t expect:
- Your car to run perfectly without maintenance
- Your HVAC system to last decades without service
Yet many homeowners expect water to flow through decades-old pipes without protection. That assumption quietly costs thousands over time.
