If you’re wondering what to expect from a free in-home water test in Irvine, one of the important things we evaluate is whether your water contains chlorine or chloramines. These disinfectants are commonly used in municipal water systems to help keep drinking water safe as it travels through the distribution system. During your Free, In-Home Water Test, we’ll explain whether they’re present, how they may affect your water’s taste or odor, and whether treatment options make sense for your home. All this with immediate results and absolutely no sales pressure.

Here’s a question I hear all the time: “Brian…why does my tap water sometimes smell like a swimming pool?”
I’m Brian McCowin. My family has been helping Orange County homeowners understand their water since 1972. Sometimes homeowners notice it first thing in the morning. Others notice it when filling a glass of water. Some only notice it while taking a hot shower.
The first assumption is usually: “There must be something wrong with my water.” Most of the time, what they’re noticing is the presence of disinfectants like chlorine or chloramines. These substances play an important role in municipal water treatment. But that doesn’t mean you shouldn’t understand how they affect your home’s water.
That’s exactly why professional testing is valuable. Think of your annual physical. Your doctor doesn’t simply tell you whether you’re healthy. They explain what the numbers mean. That’s exactly how we approach water testing.
Why are chlorine and chloramines added to drinking water?
Municipal water providers commonly use disinfectants to help protect drinking water as it travels through pipes to homes and businesses.
The two most common disinfectants are:
- Chlorine
- Chloramines
Their primary purpose is to help control harmful microorganisms within the public water system. By the time the water reaches your home, however, some homeowners notice changes in taste or odor that they’d like to improve.
What’s the difference between chlorine and chloramines?
Although they’re both disinfectants, they aren’t the same.
- Chlorine: Chlorine has been used for many years in municipal water treatment. Some homeowners describe its presence as a noticeable “pool-like” smell or taste.
- Chloramines: Chloramines are created by combining chlorine with a small amount of ammonia. Many water utilities use chloramines because they remain effective longer throughout large distribution systems.
The important thing for homeowners isn’t memorizing the chemistry. It’s understanding what’s in their water and what options are available if they’d like to improve its taste or odor.
Will my Free, In-Home Water Test check for chlorine or chloramines?
Yes.
During your professional water evaluation, we’ll assess several important water characteristics, including disinfectants when appropriate.
We commonly evaluate:
- Water hardness
- Total Dissolved Solids (TDS)
- Chlorine or chloramines
- Household water concerns
- Your treatment goals
Everything is explained while we’re in your home. There’s no waiting for laboratory reports.
Will I get the results immediately?
Absolutely.
One of the biggest advantages of our process is immediate feedback.
We do NOT:
- Collect samples and leave
- Mail water to a laboratory
- Ask you to wait days for results
- Send confusing reports later
Instead, we perform professional on-site testing right at your kitchen sink.
You’ll see the results. We’ll explain what they mean. And you’ll have plenty of time to ask questions.
How can chlorine or chloramines affect my water?
Many homeowners notice:
- Changes in taste
- Changes in odor
- Less enjoyable drinking water
- Coffee or tea that doesn’t taste quite right
Some families also notice these characteristics when:
- Filling reusable water bottles
- Making ice
- Cooking
- Preparing beverages
Not everyone notices these differences. But if you do, it’s worth understanding what’s causing them.
If chlorine or chloramines are present, does that automatically mean I need a filtration system?
Not necessarily. Here’s an insider secret from more than fifty years in the business. Testing tells us what’s in your water.
It doesn’t automatically determine what you should buy. Every homeowner has different priorities.
Some families are primarily concerned about:
- Drinking water taste
- Cooking water
- Whole-home water quality
- Protecting plumbing and appliances
The right recommendation depends on both your water and your goals. That’s why we always start with testing and not with sales.
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 water test?
Some helpful questions include:
- Is chlorine present in my water?
- Are chloramines present?
- Could they affect my water’s taste or odor?
- What treatment options are available?
- Do I need whole-home filtration or a drinking water system?
- What maintenance would be required?
There are no bad questions. Our goal is to help you understand your water and not overwhelm you with technical terms.
Why is professional testing better than relying on taste alone?
Taste is subjective. One person may notice chlorine immediately. Another person may not notice it at all.
Professional testing provides objective information about your water so you can make informed decisions based on facts rather than assumptions.
What is the smartest first step if I’m concerned about chlorine or chloramines?
The smartest first step is scheduling a professional Free, In-Home Water Test.
Don’t guess or rely on internet forums. Don’t buy equipment before understanding your water. Start with facts. Everything else becomes much easier after that.

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!
