Plumber Speaks Out: What's Building 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 shiny? No bad smell?

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

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

Until the day the toilet just won't flush anymore.

Steve Hansen knows this better than anyone. The master plumber from Vancouver has repaired over 15,000 clogged toilets in 28 years. In private homes, hotels, offices, and care facilities.

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

What's Actually Happening in 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 realize:

Not everything flows along with it.

On the inside of your drain pipes, a paper-thin layer is left behind with every flush. Grease, limescale, 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 buildup.

Steve Hansen calls it the “Biofilm Armour.”

“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 really gross:

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 centimetre than on a public toilet seat.

And the worst part: When you clean your toilet — with Lysol, Clorox, drop-in tablets, or the toilet brush — you're only cleaning the porcelain. The visible surface. The pipes behind it? You're not reaching those. Not with a brush. Not with a gel. Not with a tablet.

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)

Steve Hansen explains how a clog actually forms:

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

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

But: The pipe's diameter is already narrowing. From 100 mm to 90 mm. Then 80 mm. Imperceptibly.

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

The water drains a bit slower. Sometimes it gurgles. Occasionally an unpleasant odour 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 returns 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. $250 to $500.

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

Why Regular Cleaning Products Don't Solve the Problem (And Often Make It Worse)

Steve Hansen has seen it all over his 28 years. And he has a very clear opinion on the common methods:

Lysol, Clorox, 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 can use Lysol every single day — your pipes will still be full of buildup.”

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 doesn't fully remove it. And the worst part: These products attack your pipes. Especially in older homes with plastic or cast-iron pipes, it can get really expensive.”

Plunger: “Works on 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: “It bores a hole through the clog. Fair enough. But the biofilm on the inside of the pipes? The snake doesn't reach it. 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 $250 and $500. And I tell every customer: I'm happy to come. But if you just maintained your pipes, you'd never need to call me again.”

The Discovery That Made Steve Hansen Skeptical — And Then Convinced Him

“A colleague from the Netherlands 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.”

Steve Hansen 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. Steve watched how the powder, upon contact with water, expanded into a dense foam that worked its way down into the pipe. After 20 minutes: a 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 — 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 inside walls of the pipe.

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

As soon as the powder hits the water, millions of microscopic foam bubbles form. 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 single pore, every nook, every bend in the pipe system. Into 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 surrounds the biofilm. The micro-bubbles press against the pipe walls and envelop 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, limescale, cellulose, bacterial colonies — at the 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 Realize: 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 Steve Hansen. “The porcelain is spotless. But right behind it, inside the pipe, there's a centimetre-thick layer of bacteria. And every time they flush, microscopic particles from this biofilm are launched upward.”

The phenomenon is called “Toilet Aerosol.” When flushing, the finest water droplets are propelled up to 1.8 metres into the air. These droplets contain bacteria from the pipe — not just from the toilet bowl itself.

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

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

FizzClean doesn't just clear clogs — it removes the entire biofilm inside the pipe. The source of the bacteria 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 those spots under the rim where no brush can reach. Limescale, urine stains, discolouration — all dissolved and flushed away.

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

What Users Report After the First Use

Wayne K., from Calgary: “Our toilet had been draining slowly for months. Slower and slower. My wife was 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 $20 you've ever spent.”

Margaret S., from Ottawa: “I had the plumber out twice a year. Always the same spot, always the same clog. $300 every single time. My grandchild gave 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.”

Henry B., from Edmonton: “I had tried everything. Plunger, drain cleaner, even boiling water. Nothing helped long-term. FizzClean was different. You can actually see the foam working in 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.”

Ingrid W., from Winnipeg: “It was the hygiene aspect that convinced me. My daughter is a nurse, and she explained to me what builds up in 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.”

Erica D., from Toronto: “Emergency plumber on a Sunday night. $450. 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 drains: 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 residue? 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 stink.

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

“I used to have five different cleaning products in the house,” says Steve Hansen. “Now I only recommend one thing to my customers: FizzClean. For anything that involves pipes.”
