Why Does My Drain Keep Clogging?

(And Why It Always Seems to Happen at the Worst Time)

If your sink, shower, or tub keeps clogging like it’s got a personal vendetta against you… you’re not alone. Around here, we hear this question all the time:

“Wally, why do I keep clearing my drain just for it to clog again a week later?”

Well pull up a chair and grab some sweet tea, because there’s usually a reason that stubborn clog keeps coming back. Let’s talk about what might be happening in those pipes.

1. You’re Only Clearing Part of the Clog

A lot of store-bought drain cleaners or quick plunges only poke a small hole through the blockage. Water starts draining again, so it looks fixed… but the rest of the gunk is still hanging around in the pipe.

Think of it like punching a tunnel through a mud pile. The water may squeeze through for a while, but eventually that tunnel collapses and the clog returns.

Common leftover clog materials include:

• Hair
• Grease
• Soap scum
• Food particles
• Toothpaste buildup

When that leftover debris grabs more stuff flowing by… boom 💥 you’ve got another clog.

2. Grease Is Sneaking Down Your Kitchen Sink

One of the biggest repeat offenders is cooking grease.

You might pour grease down the drain as a liquid, but once it cools, it turns into a sticky, waxy mess that coats the inside of your pipes.

Over time, that grease layer becomes the perfect trap for:

• Food scraps
• Coffee grounds
• Rice
• Pasta
• Soap residue

Before long, your drain pipe starts narrowing like an old country road.

Tip from Wally:
If it came out of a frying pan, it doesn’t belong in the drain. Pour it into a disposable container and toss it in the trash instead.

3. Hair Is Building a Net in Your Bathroom Drain

If your shower drains slower than molasses in January, hair is usually the culprit.

Hair doesn’t dissolve, and once it gets into the pipe it acts like a fishing net catching everything else:

• Shampoo residue
• Soap scum
• Conditioner
• Dirt and oils

That combo slowly forms a nasty little knot that keeps growing.

A simple hair catcher for your shower drain can save you a whole lot of trouble.

4. Soap Scum Is Coating the Pipes

Even if you’re careful about what goes down the drain, soap itself can cause problems.

Traditional bar soaps combine with minerals in water to form soap scum, which sticks to the inside of pipes. Over time it creates a sticky layer that catches debris and slows down water flow.

This is especially common in:

• Bathroom sinks
• Bathtubs
• Showers

5. There May Be a Bigger Plumbing Issue

Sometimes the clog isn’t in the drain you see—it’s deeper in the plumbing system.

Recurring clogs can be caused by things like:

• Tree roots in sewer lines 🌳
• Pipe scale buildup
• Pipe bellies (sagging pipes that trap debris)
• Improper pipe slope
• A clogged main drain line

If multiple drains in your home are slow, the problem may be in the main line, not just your sink.

6. Store-Bought Drain Cleaners Can Make Things Worse

Those chemical drain cleaners might promise miracle results, but they can actually:

• Damage pipes
• Eat away at seals
• Harden grease clogs
• Leave debris behind

And if the clog isn’t fully cleared, it’ll just keep coming back.

So What’s the Real Fix? 🛠️

The real solution is removing the entire blockage, not just breaking a hole through it.

That might involve:

• Professional drain clearing
• Drain augers (snakes)
• Hydro jetting
• Inspecting the line with a camera

Once the buildup is fully removed, your drain should flow like it’s supposed to.

Final Thoughts from Wally the Walrus

Drains don’t clog overnight. It’s usually a slow buildup of everyday stuff that eventually blocks the pipe.
