If you’re wondering why does my drain keep clogging even after snaking it, plenty of homeowners run into the same thing. Snaking pulls out the chunk blocking the flow, but it often leaves the layer stuck to the pipe walls. That layer grows back fast.
Why a Drain Snake Doesn’t Always Solve the Problem
A drain snake, also called a plumbing auger, works like a can opener, not a bottle brush. It breaks through the clog and creates a path. But grease and soap scum coating the inside of the drain pipe usually stay put.
This is why my drain is still clogged after snaking is such a common question. The snake did its job. It just didn’t do the whole job. For a deeper clean, hydro jetting uses high-pressure water to strip buildup from the pipe walls instead of just poking through it.
Common Reasons Your Drain Keeps Clogging
Several things cause repeat clogs. Some are simple. Others point to a bigger issue in your plumbing system.
The Clog Was Only Partially Removed
A snake can push part of the clog aside without breaking it apart fully. Leftover material sticks near the P-trap and catches new debris fast. This is one common answer to what causes a drain to keep clogging.
Grease, Soap Scum, or Hair Buildup
Your kitchen sink drain deals with grease buildup and food waste daily. Grease cools and hardens inside the pipe, narrowing it bit by bit. Your bathroom sink drain collects hair, clogs, and soap scum instead. Both build slowly, so a quick snake job rarely clears them for good. That’s often why does my kitchen sink keep clogging and why does my bathroom sink keep clogging get asked so much.
Tree Roots Blocking the Sewer Line
Yes, tree roots can cause repeated drain clogs. Roots search out moisture, and a small crack in your sewer line is an easy target. A snake might cut through roots temporarily, but they grow back unless the crack gets sealed.
Pipe Damage or Misaligned Drain Pipes
Old pipes shift, crack, or sag over time. A dip in the drain line collects wastewater instead of letting it flow through. Pipe scale and mineral buildup from hard water make it worse. No amount of snaking fixes a structural pipe problem.
A Main Sewer Line Blockage
Can a sewer line problem cause recurring drain clogs? Absolutely. If every drain backs up around the same time, the issue is likely in the main sewer line. This usually needs a sewer camera inspection to find the exact cause.

Warning Signs the Problem Is More Than a Simple Clog
Watch for these signs. Multiple drains back up at once. Water drains slowly even right after snaking. You hear gurgling from the drain vent. Odors keep returning from the drain line. Any of these points to a bigger issue inside your plumbing system, not just stuck debris.
When Professional Drain Cleaning Is the Better Solution
So, what is the best solution for recurring drain clogs? In most cases, it’s professional drain cleaning. A licensed plumber has tools a homeowner doesn’t, including hydro jetting equipment and cameras that show what’s happening inside the pipe.
Does drain snaking remove the entire clog? Rarely, especially with grease or scale buildup. Hydro jetting clears the full width of the pipe, not just a narrow channel through the middle.
When should I call a plumber for a clogged drain? If snaking hasn’t worked twice, or multiple drains are affected, it’s time to call in help. AAA Auger offers professional drain cleaning services that go beyond a basic snake job, using camera inspections and jetting to clear the entire pipe and find the real cause.
How much does it cost to fix a recurring drain clog? Cost depends on the cause. Hydro jetting costs less than a sewer line repair. Catching the problem early almost always saves money.
If store-bought chemical cleaners haven’t worked either, it’s worth reading whether store-bought drain cleaners are safe for older pipes before trying another bottle. They can damage aging pipes further with repeated use.
Conclusion
A drain snake is a good first step, but it isn’t always a permanent fix. Grease, roots, scale, and structural pipe issues all cause clogs to return no matter how many times you snake them. If your drain keeps clogging, the smarter move is a full inspection and a cleaning method suited to the actual cause.
AAA Auger is a trusted plumbing company serving Texas homeowners with licensed plumbers, camera inspections, and hydro jetting for stubborn, recurring clogs. Don’t wait for a small clog to turn into a sewer line emergency.
FAQs
Can frequent drain clogs damage my plumbing system over time?
Yes. Repeated clogs strain pipe joints and can lead to leaks if left untreated for too long.
Is it safe to keep using chemical drain cleaners on recurring clogs?
Not really. They can corrode older pipes and don’t fix the underlying cause.
Can hard water contribute to recurring drain clogs?
Yes. Hard water leaves mineral buildup and pipe scale inside drain lines, narrowing the pipe faster.
How long does professional drain cleaning typically take?
Most jobs take one to two hours, depending on severity and whether a camera inspection is needed.
Can recurring drain clogs reduce my home’s plumbing efficiency?
Yes. Slow drains strain your plumbing system and can lead to backups affecting multiple fixtures at once.
