If you’re wondering what to expect from a free in-home water test in Irvine, summer is an excellent time to schedule one. Hot weather often means higher water consumption, more guests, increased ice production, and heavier use of your home’s plumbing and water filtration system. A water quality check helps you understand your water quality, identify concerns such as hard water, chlorine, chloramines, or elevated Total Dissolved Solids (TDS), and determine whether your current water treatment system is still meeting your family’s needs, all with immediate results and absolutely no sales pressure.

Every summer, I notice something interesting. Homeowners start paying more attention to their water.
I’m Brian McCowin. My family has been helping Orange County homeowners understand their water since 1972. Maybe it’s because everyone’s drinking more, or the kids are home from school, or family and friends are visiting more often.
Whatever the reason, summer has a way of putting your home’s water system to the test. People suddenly notice things like: “The water doesn’t taste quite as fresh.” “Our ice doesn’t look as clear.” “The shower doors seem to have more spots.” “We’re buying bottled water again.”
Sometimes nothing has changed with your water, while other times your family’s water usage has simply increased enough to reveal issues that were already there. Think of summer like a stress test for your home. Your air conditioner and refrigerator work harder, and your water system often does too.
That’s why mid-summer is one of my favorite times to check a home’s water.
Why is summer a good time for a water quality check?
Most families naturally use more water during the warmer months.
Common reasons include:
- Drinking more water
- Filling reusable bottles
- Making more ice
- Hosting guests
- Preparing cold drinks
- Cooking at home more often
When water usage increases, it’s easier to notice changes in taste, odor, or performance. A mid-summer evaluation helps you understand whether your water treatment system is keeping up.
What happens during a Free, In-Home Water Test?
The appointment is designed to be simple, informative, and pressure-free. We begin by learning about your household and any concerns you may have. Then we perform professional on-site testing.
Depending on your home’s needs, we commonly evaluate:
- Water hardness
- Total Dissolved Solids (TDS)
- Chlorine or chloramines
- Taste and odor concerns
- Household water usage
- Your treatment goals
Everything is explained while we’re in your home. There’s no waiting for laboratory reports.

Will I receive my results immediately?
Yes. One of the biggest advantages of our process is immediate feedback.
We do NOT:
- Collect samples and leave
- Send water to a laboratory
- Make you wait several days
- Email technical reports later
Instead, you’ll receive your results during the appointment. We’ll explain what they mean and answer every question you have.
What if I already have a water filtration system?
A water quality check can still be valuable. Your household may have changed since your system was installed.
Perhaps you’ve:
- Added family members
- Started working from home
- Increased water usage
- Purchased new appliances
- Delayed routine maintenance
A professional evaluation helps determine whether your current system is still meeting your needs.
Will the appointment become a sales presentation?
No. Here’s an insider secret from more than fifty years in the business: The best recommendations never require pressure.
At McCowin Water, we believe in:
- Education first
- Honest answers
- Professional testing
- Customized recommendations
- Giving homeowners time to decide
A recommendation that’s right today will still be right tomorrow. You should never feel rushed.
Why do different companies recommend different water treatment 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 and not what’s sitting in our warehouse.
What questions should I ask during my appointment?
Some of the best questions include:
- Is my water hard?
- What does my TDS reading mean?
- Is chlorine or chloramine present?
- Is my current filtration system performing properly?
- Would whole-home filtration benefit my family?
- What maintenance should I plan for?
A good consultation should leave you feeling informed—not overwhelmed.

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!
