If you’re wondering what to expect from a free in-home water test in Irvine, you’ll receive more than just a few numbers. You’ll get a clear explanation of what those results mean for your home and family. During your Free, In-Home Water Test, we evaluate key water characteristics such as water hardness, Total Dissolved Solids (TDS), and chlorine or chloramines, then explain how each one may affect your drinking water, plumbing, appliances, and daily life. At McCowin Water, you’ll receive immediate results with honest answers and absolutely no sales pressure.

Here’s a question homeowners ask me all the time: “Brian…what do all these numbers actually mean?”
I’m Brian McCowin. My family has been helping Orange County homeowners understand their water since 1972. I’ll never forget a homeowner who looked at their water test results and said, “I guess these numbers are supposed to mean something.” They were right.
The problem wasn’t the test, but that nobody had explained it. Think about getting blood work from your doctor. Seeing the numbers alone doesn’t tell you much. What matters is having someone explain what they mean and whether you should be concerned. Water testing works the same way.
The goal isn’t to impress you with technical data but to help you understand your home’s water in plain English.
Let’s walk through what you can expect.
What happens after my water is tested?
Once we’ve completed the testing, we sit down with you and review the results together. There’s no rushing, no technical jargon, no confusing charts.
Instead, we’ll explain:
- What each measurement means
- Whether it’s typical for Orange County
- How it may affect your home
- Whether any treatment options are worth considering
Our job isn’t just to test your water. It’s to help you understand it.
What does the water hardness result mean?
One of the first things we evaluate is water hardness.
Hard water contains naturally occurring minerals, primarily:
- Calcium
- Magnesium
If your water is hard, we’ll explain how it may contribute to:
- White spots on dishes
- Mineral buildup around faucets
- Cloudy shower doors
- Scale inside appliances
- Increased cleaning around sinks and fixtures
We’ll also discuss whether treating hard water makes sense based on your home’s needs.
What does the TDS number tell me?
Another important measurement is Total Dissolved Solids (TDS). TDS refers to the dissolved minerals and other substances naturally present in your water.
During your appointment, we’ll explain:
- What is your TDS reading
- Whether it’s typical for municipal water in Orange County
- How it relates to taste and overall water quality
TDS is one piece of the overall picture and not the entire story. That’s why we evaluate several water characteristics together.
What do chlorine or chloramine results mean?
Municipal water providers commonly use disinfectants to help keep drinking water safe as it travels through the distribution system.
Your test may evaluate:
- Chlorine
- Chloramines
If they’re present, we’ll explain:
- Why are they used
- Whether they may affect taste or odor
- Which treatment options may improve your drinking water experience
Again, our goal is education and not creating unnecessary concern.
Will I know immediately if something needs attention?
Yes. One of the biggest advantages of our process is immediate feedback.
We do NOT:
- Send water samples to a laboratory
- Make you wait several days
- Email confusing reports later
Instead, we review everything with you during the appointment so you leave with answers and not more questions.
Do abnormal results automatically mean I need a filtration system?
Not necessarily. Here’s an insider secret from more than fifty years in the business. Water testing tells us what’s happening.
It doesn’t automatically determine what you should buy. Every family has different priorities.
Some homeowners care most about:
- Better tasting water
- Appliance protection
- Reducing scale buildup
- Whole-home water quality
Others may be perfectly satisfied with their current water. That’s why recommendations should always follow testing and not the other way around.
Why do different companies interpret water tests differently?
Many companies only sell one manufacturer’s equipment. That creates a challenge.
At McCowin Water, we’re like an Auto Mall for water.
We’re not tied to one manufacturer. We carry a broad selection of premium water treatment technologies because every home’s water is different. That flexibility allows us to recommend what’s best for your water and not what’s sitting in our warehouse.
What questions should I ask when reviewing my results?
A good consultation should encourage questions such as:
- Is my water considered hard?
- What does my TDS reading actually mean?
- Is chlorine or chloramine present?
- Which issues are worth addressing?
- What treatment options are available?
- What maintenance would be required?
The more you understand your results, the easier it becomes to make confident decisions.

Posted on Google Henry 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 on Google Ethan 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 on Google Tom 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 on Google Mike 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 on Google Juliet WilliamsTrustindex verifies that the original source of the review is Google. Maaison was great and super helpful!
