Plumber Speaks Out: What Builds Up in the Pipes Behind Your Toilet Is Something No One Wants to See — and It's the Real Cause of Clogged Toilets

He’s repaired over 15,000 toilets. What he finds in the sewer pipes makes even his stomach turn. Now he reveals why most clogs don’t actually happen suddenly — and how a German cleaning powder solves the problem where no tool can reach.

The Disgusting Truth Your Plumber Never Tells You

Does your toilet look clean? Is the porcelain shining? No bad smell?

Then take a closer look. Or better yet: Look where you can’t see.

Right behind your toilet, a pipe system begins that you never get to see. A dark, damp labyrinth of drain pipes, bends, and joints. And it’s precisely there that something is happening that most people never discover in their lifetime — until it’s too late.

Until the day the toilet won’t flush anymore.

Mike Reynolds knows this better than anyone. The master plumber from Columbus, Ohio, has repaired over 15,000 clogged toilets in 28 years. In private homes, hotels, offices, and nursing homes.

“People call me and say: The toilet suddenly clogged. But that’s almost never true. A toilet doesn’t just clog out of nowhere. The problem builds up over months and years. Deep down in the pipes, where you can’t see it and you can’t smell it — until it’s too late.”

What Actually Happens Inside Your Pipes (and Why You Don’t Notice It)

Every time you flush, water flows through your pipes. So far, so good. But what most people don’t know:

Not everything flows along with it.

On the inside of your drain pipes, a paper-thin layer is left behind with every flush. Grease, lime, soap residue, organic matter, cellulose from toilet paper. Individually, it’s barely measurable. But over weeks and months, this layer hardens into a tough, sticky coating.

Mike Reynolds calls it the “Biofilm Armor.”

“Imagine your pipes are like arteries. And this biofilm is like cholesterol. It builds up layer by layer. Slowly. Invisibly. And at some point, the pipe is so narrowed that nothing can get through anymore.”

And now it gets truly disgusting:

This biofilm isn’t just grime. It’s a living ecosystem of bacteria, fungi, and microorganisms. In an average toilet drain pipe, there are more bacteria per square inch than on a public toilet seat.

And the worst part: When you clean your toilet — with Clorox, bleach, drop-in tabs, or the toilet brush — you’re only cleaning the porcelain. The visible surface. The pipes behind it? You can’t reach them. Not with a brush. Not with a gel. Not with a tab.

You’re polishing the front door while the rats are breeding in the basement.

The 3 Phases of a Clogged Pipe (and Why Phases 1 and 2 Are Invisible)

Mike Reynolds explains how a clog actually develops:

Phase 1: The Invisible Buildup (Month 1–12)

The biofilm begins to deposit on the inside of the pipes. Thin as a membrane. Invisible. Odorless. Your toilet works flawlessly. You notice nothing.

But: The pipe’s diameter is already narrowing. From 4 inches to 3.5 inches. Then 3 inches. Imperceptibly.

Phase 2: The First Warning Signs (Month 12–24)

The water drains a little slower. Sometimes it gurgles. Occasionally, an unpleasant smell rises up — especially in warm weather. Most people think: “It’ll be fine.” Or they pour some drain cleaner down.

The drain cleaner dissolves the top layer. But the biofilm underneath? It stays put. The smell comes back two weeks later.

Phase 3: The Clog (Sudden, But Predictable)

The pipe’s diameter is now so narrowed that a single slightly larger piece of toilet paper, a wet wipe, or a slightly firmer stool blocks the remaining passage.

The water rises. Panic. Plunger comes out. Emergency plumber on a Sunday night. $200 to $500.

“And then I tell people: This didn’t have to happen. If they had just cleaned their pipes regularly — not the toilet, but the pipes — this never would have happened.”

Why Ordinary Cleaning Products Don’t Solve the Problem (and Often Make It Worse)

Mike Reynolds has seen it all in his 28 years. And he has a very clear opinion about the common methods:

Clorox, Lysol, and similar products (Liquid toilet cleaners): “They clean the porcelain. Period. The liquid runs through the pipes when you flush, but it has no contact time. The biofilm in the pipes isn’t even touched. You could use Clorox every single day — your pipes will still be full of gunk.”

Chemical drain cleaners (Drano, Liquid-Plumr): “They’re aggressive, yes. They dissolve the top layer of the clog. But the biofilm that’s been building up for months is so firmly attached that even caustic soda won’t remove it completely. And the worst part: These products attack your pipes. Especially in older homes with plastic or cast-iron pipes, that can get really expensive.”

Plunger: “Works for minor clogs. But it just pushes the blockage further down. The biofilm stays. The next clog is guaranteed. And for more stubborn clogs? Completely useless.”

Drain snake: “Bores a hole through the clog. Fine. But the biofilm on the inside of the pipes? The snake doesn’t reach that. You’re boring a tunnel through the gunk instead of removing it. The pipe keeps narrowing.”

Emergency plumber: “Of course I solve the problem. But it costs between $200 and $500. And I tell every customer: I’m happy to come out. But if you just maintained your pipes, you’d never need to call me again.”

The Discovery That Made Mike Reynolds Skeptical — and Then Convinced Him

“A colleague over in Europe told me about a cleaning powder. You pour it into the toilet, and the foam crawls down into the pipes on its own. Dissolves the biofilm. Clears clogs. No tools needed.”

Mike Reynolds laughed.

“I’ve been doing this for 28 years. If a miracle product like that existed, I’d know about it.”

His colleague sent him a video. Mike watched how the powder, upon contact with water, swelled into a dense foam that expanded downward into the pipe. After 20 minutes: a completely clear drain. Without lifting a finger.

“I watched the video three times. Then I ordered it.”

The product: FizzClean.

Why FizzClean Works Where Everything Else Fails — Deep Down in Your Pipes

FizzClean is not a liquid cleaner. It’s a concentrated powder with a special micro-foam technology. And that’s exactly where the crucial difference lies:

Liquid cleaners flow downward — right past the pipe walls.

FizzClean foam expands — and presses outward against the pipe walls.

As soon as the powder touches water, millions of microscopic foam bubbles are created. This foam actively expands and fills the entire pipe — 360 degrees, from wall to wall.

The foam doesn’t stay on the surface. It crawls into every pore, every crevice, every bend in the pipe system. To places where no brush, no drain snake, and no liquid cleaner can ever reach.

What happens over the next 20 minutes:

Step 1: The foam envelops the biofilm. The micro-bubbles press against the pipe walls and surround the years-old biofilm from all sides.

Step 2: Enzymes break down the biofilm from within. The formula contains specially developed enzymes that dissolve organic deposits — grease, lime, cellulose, bacterial colonies — at a molecular level. The biofilm is literally eaten away from the inside.

Step 3: The foam carries everything away. When you flush, the foam takes all the dissolved biofilm, bacteria, and deposits with it. What’s left behind: clean, exposed pipe walls. Full diameter. Free-flowing drain.

The result: Not only is the current clog resolved — but the very biofilm that would have caused the next clog is completely gone. Your pipes are as clean as the day they were installed.

What Most People Don’t Know: Your Pipes Are a Breeding Ground for Dangerous Bacteria

And now we get to the part that’s truly alarming.

The biofilm in your pipes isn’t just the cause of clogs. It’s also a massive hygiene problem.

“People clean their toilet every single day,” says Mike Reynolds. “The porcelain sparkles. But right behind it, inside the pipe, there’s a half-inch-thick layer of bacteria. And every time they flush, microscopic particles from this biofilm are launched into the air.”

The phenomenon is called “Toilet Aerosol.” When flushing, the finest water droplets are propelled up to 6 feet into the air. These droplets contain bacteria from the pipe — not just from the toilet bowl itself.

That means: Even if your porcelain is spotless — bacteria from the biofilm deep in your pipes are landing on your towels, your toothbrush, your bathroom floor.

You can clean the toilet as much as you want. As long as the biofilm is sitting inside the pipes, your bathroom isn’t truly clean.

FizzClean doesn’t just remove clogs — it removes the entire biofilm inside the pipe. The bacterial source is eliminated. Not masked, not covered up — eliminated.

And as an added bonus: The foam also cleans the toilet bowl itself on its way through the pipe — including the spots under the rim where no brush can reach. Lime, urine scale, discoloration — everything is dissolved and flushed away.

One product. Clear pipes. Clean toilet. Bacteria gone.

What Users Report After the First Use

Gary K., from Phoenix: “Our toilet had been flushing slowly for months. Slower and slower. My wife was already about to call a plumber. I poured FizzClean in, waited 20 minutes, and flushed. The water shot through like there was no tomorrow. And the smell that had been coming from the drain for weeks — completely gone. My wife said: That’s the best $30 you’ve ever spent.”

Margaret S., from Portland: “I had the plumber out twice a year. Always the same spot, always the same clog. $250 every single time. My granddaughter got me FizzClean as a gift. I now use it preventatively once a month. It’s been 8 months without a single clog. The plumber is probably wondering why I haven’t called.”

Brian H., from Tampa: “I’d tried everything. Plunger, drain cleaner, even boiling water. Nothing helped in the long run. FizzClean was different. You can literally see the foam working inside the pipe. After 20 minutes, everything was clear. And the best part: It doesn’t come back. Because all the gunk in the pipes is gone, not just the blockage itself.”

Linda W., from Denver: “It was the hygiene aspect that convinced me. My daughter is a nurse, and she explained to me what builds up inside the pipes. Since then, I’ve been using FizzClean every two weeks. Not because there’s a clog — but precisely so it never gets to that point. And the smell in the bathroom? Completely gone. It just smells like nothing. And that’s exactly how it should be.”

Donna D., from Chicago: “Emergency plumber on a Sunday night. $400. Just because the toilet was clogged. My son said: Mom, this is not happening to you again. So he ordered FizzClean for me. That was 6 months ago. Since then: Zero problems. Zero dollars to the plumber.”

FizzClean Works Everywhere Pipes Can Clog

What many people don’t realize: FizzClean doesn’t just work in the toilet.

Bathroom sink drain: Hair, soap, toothpaste — the same biofilm layer builds up here too. Powder in, water on, wait 20 minutes. Clear drain.

Shower and bathtub: Clogged shower drains from hair and soap scum? FizzClean dissolves the blockage and the biofilm behind it.

Kitchen sink: Grease deposits in the drain? The foam crawls through the pipes and dissolves everything. No more stench.

Washing machine drain: Lint, detergent residue, bacteria — all dissolved.

“I used to have five different cleaning products in the house,” says Mike Reynolds. “Now I recommend just one thing to my customers: FizzClean. For everything that has to do with pipes.”
