If you’re wondering what to expect from a free in-home water test in Irvine, it’s important to understand one thing: a standard Free, In-Home Water Test cannot directly identify PFAS (per- and polyfluoroalkyl substances). Detecting PFAS requires specialized laboratory testing using advanced analytical equipment. However, a professional in-home water test is still an excellent first step because it evaluates your overall water quality, explains your home’s water characteristics, discusses any concerns you may have about PFAS, and helps determine whether additional laboratory testing or filtration options are appropriate.

One of the questions I hear more often today is: “Brian…can your free water test tell me if I have PFAS?”
I’m Brian McCowin. My family has been helping Orange County homeowners understand their water since 1972.
It’s a great question and it’s one that deserves an honest answer. The answer isn’t simply “yes” or “no.” It’s understanding what a free in-home water test is designed to do and what it isn’t.
Think about visiting your family doctor. A routine checkup tells you a lot about your overall health: blood pressure, heart rate, weight, general wellness. But if your doctor suspects something very specific, they may recommend specialized laboratory testing.
Water testing works the same way. A professional in-home water test provides valuable information about your home’s water, while certain contaminants like PFAS, require advanced laboratory analysis. Honest advice starts with explaining the difference.
What are PFAS?
PFAS stands for per- and polyfluoroalkyl substances.
These are a large group of man-made chemicals that have been used in various industrial and consumer products for decades because they resist heat, water, and oil.
Because PFAS are measured at extremely small concentrations, detecting them requires specialized laboratory equipment and testing methods. They cannot be identified by appearance, taste, or smell.
Can a Free, In-Home Water Test detect PFAS?
Here’s the straightforward answer. A standard Free, In-Home Water Test is not designed to directly detect PFAS.
Instead, during your appointment we evaluate important water quality characteristics such as:
- Water hardness
- Total Dissolved Solids (TDS)
- Chlorine or chloramines
- General water quality
- Household water usage
- Your water treatment goals
If PFAS is one of your concerns, we’ll discuss it with you honestly and explain whether specialized laboratory testing would be appropriate. We believe it’s better to be transparent than to promise a test can do something it cannot.
Why can’t PFAS be tested during a home visit?
Here’s an insider secret from more than fifty years in the business.

Some things simply require laboratory equipment. PFAS testing involves detecting substances at extremely low concentrations using sophisticated analytical methods.
That’s not something a handheld meter or kitchen-sink demonstration can accurately measure.
Any company claiming to instantly “test for PFAS” during a routine in-home visit deserves careful questions about how that testing is being performed.
What should I expect from a Free, In-Home Water Test?
Your appointment is designed to help you better understand your water.
We perform professional on-site testing and explain:
- Water hardness
- Total Dissolved Solids (TDS)
- Chlorine or chloramines
- Your household’s water usage
- Your family’s concerns
- Potential treatment options if appropriate
You’ll receive immediate results for the tests performed on-site. We do NOT send these routine measurements to a lab and ask you to wait for answers.
If PFAS requires lab testing, why schedule a free water test?
Because it’s still the smartest first step. A professional consultation allows us to:
- Understand your concerns.
- Review your home’s water source.
- Evaluate overall water quality.
- Discuss whether specialized PFAS testing makes sense.
- Explain treatment options if additional testing confirms the need.
Water treatment should never begin with assumptions. It should begin with understanding.
Can filtration systems help address PFAS?
Some water treatment technologies are designed to reduce certain PFAS compounds when properly selected, installed, and maintained.
However, recommending a system before understanding your water or before confirming whether PFAS is actually a concern wouldn’t be responsible. That’s why we believe in:
- Professional evaluation.
- Honest conversations.
- Customized recommendations.
- No-pressure consultations.
Every home deserves a solution based on facts rather than fear.
Why do different companies recommend different systems?
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, not what’s sitting in our warehouse.
What questions should I ask if I’m concerned about PFAS?
A trustworthy water professional should be willing to answer questions like:
- Can your in-home test detect PFAS?
- Would laboratory testing be appropriate for my situation?
- What does my routine water test tell us?
- Are there filtration options designed for my concerns?
- What maintenance would those systems require?
- How do I know which solution fits my home?
Honest answers build confidence. Pressure never does.

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!
