The McCowin Guarantee™

“If It Doesn’t Work, We Pull It Out.”
No gimmicks. No fine print. No B.S.

I’ll tell you a little story.

A few years back, I met a woman in Irvine… let’s call her Sharon.

She had that nervous look I’ve seen hundreds of times.
The look of someone who’d spent thousands on the “top-rated” water system from a big-box brand…
…only to realize months later it wasn’t doing the job.

Her water still smelled like chlorine.
Her skin still itched after every shower.
Her dishwasher was wrecking her glassware.

She called the company.
They said “just give it some time.”
She waited.

She called again. They said she was using it wrong.
Let that sink in.

She didn’t need more customer service.
She needed someone to take responsibility.

So I sat down at her kitchen table and said the words that McCowin Water is built on:

“If it doesn’t do what I say it will do, we’ll pull it out and replace it. No charge. That’s the McCowin Guarantee.”

She looked at me like I was lying.

And I get it.

Because most companies talk big before the check clears, and disappear after.

Not us.


We Don’t Sell Filters.

We Sell Peace of Mind.

Here’s what you need to know about how we operate:

When we recommend a system, we’re not guessing.
We don’t push random brands or mark up generic models.

We engineer solutions based on your water chemistry, home layout, lifestyle, health priorities, and local infrastructure.

We know where your water comes from.
We know what’s in it.
We know what it’s doing to your pipes, your skin, your family’s long-term health… and your home’s value.

When we say it will work, we don’t hope.
We guarantee it.


So What’s the Guarantee, Exactly?

Let’s make it plain:

If the system we install doesn’t perform the way we promised…
If your water doesn’t taste, feel, or behave the way we said it would…
We’ll pull the whole system out. And either replace it or refund you.

Because your trust is worth more than the sale.


Why We Created This Guarantee (And Why Nobody Else Offers It)

Most companies treat your home like a transaction.
We treat it like a temple.

It’s where your kids grow up.
Where your spouse makes coffee in the morning.
Where your dog drinks from the bowl.
Where you shower before a job interview or rinse produce for dinner.

That water matters.

But here’s the part nobody wants to say out loud:

Most systems on the market are either overpriced junk or outdated tech; designed to look good on paper, not to protect your family for the next 20 years.

We’ve ripped out “brand name” systems that failed within 18 months.
We’ve saved families from $12,000 floods caused by low-grade installs.

We’ve replaced systems sold by people who didn’t even bother to test the water.

That’s why the McCowin Guarantee exists.

Because in a world full of noise and nonsense, you deserve one company that tells the truth and stands behind it.


Why You’ll Feel Different the Moment We Start

The truth is, the real “product” you get with us…
…isn’t the system.

It’s the feeling you get when you know you’re in good hands.

It’s the sigh of relief you’ll breathe when the itch stops, the stains disappear, and your glassware sparkles again.

It’s the quiet confidence of knowing you made the right decision, and you won’t have to think about it ever again.

No more guessing.
No more Googling.
No more plumbing surprises at 2am.


Here’s What You Actually Get with McCowin Water:

  • Customized, not cookie-cutter: We design every system based on your exact home and local water conditions.
  • Sales tax? We pay it. You won’t see it. We absorb the cost. Why? Because you deserve transparency.
  • Drain lines, power, plumbing? We handle it. Our install team is white-glove only. No corners cut.
  • Full parts & labor warranty. Most companies hide behind the manufacturer. We stand behind our install.
  • Lifetime service support. If something isn’t working, we’re one call away. No runaround. No robots.
  • 100% system performance guarantee. That means: if it doesn’t work, we fix it or remove it.

No stress.
No mess.
No “please hold.”


What Happens If You’re Not Happy?

You call.
We answer.

No third-party. No waiting weeks.
We’ll come out. Test the system. Check the water.

If it’s not performing?

We fix it or pull it out. No drama. No invoice. No B.S.


This Is Bigger Than Just Water

The McCowin Guarantee isn’t about plumbing.
It’s about how we treat people.

It’s about restoring the kind of service that’s gone missing from this world:

  • Doing what we say we’ll do.
  • Showing up on time.
  • Never selling what someone doesn’t need.
  • Making it right, even if it costs us.

Because we’re not in the water business.

We’re in the trust business.


What Customers Say After the Install

“My dishes haven’t looked this clean in years.”
“My daughter’s eczema cleared up in a week.”
“I didn’t believe you at first… now I tell everyone I know.”
“It’s the best thing I’ve done for my home since I bought it.”

People feel it.
See it.
And taste it.

That’s why over 85% of our business comes from referrals alone.


Final Word from Brian

Look…

I’ve seen too many families get burned.

Too many seniors overcharged.

Too many single moms misled by slick sales guys with scripts and quotas.

That’s not how we do it here.

We built this company like we built our name: one family at a time, one system at a time, one promise kept at a time.

If you’ve been burned before, I get it.

Let me earn your trust, and guarantee the result.

Because at McCowin Water…

If it doesn’t work, we pull it out.

You’ve got nothing to lose.
