You’re standing in a half-inch of lukewarm, grey soapy water because your shower decided to quit draining. It’s gross. Your first instinct is probably to grab that jug of liquid "drain cleaner" sitting under the sink, but please, put it down. Seriously. Those chemicals are basically acid in a bottle; they’re terrible for your pipes, worse for the environment, and honestly, they rarely work on a tough clog. You need a snake. But here’s the thing: if you go to Home Depot and just grab the first "snake" you see, you might end up scratching your expensive porcelain toilet or, worse, snapping a cheap cable off inside your wall.
Not all types of drain snakes are created equal.
Some are delicate little plastic strips with teeth. Others are heavy-duty monsters powered by 120-volt motors that can chew through tree roots. Picking the wrong one isn't just inefficient—it can be a literal disaster for your plumbing. I’ve seen DIYers use a closet auger in a kitchen sink and wonder why they can't get around the P-trap. It’s because plumbing is a game of geometry and torque.
The Basic Hand Auger (The Gateway Snake)
Most homeowners start here. This is the classic drum auger. It’s got a canister, a crank handle, and a cable—usually about 25 feet of it. You’ll find these at any hardware store for twenty bucks. It’s designed for "simple" clogs. Think hair. Think a bit of grease buildup in the kitchen line.
You feed the cable in by hand, tighten the lock, and spin. It’s tactile. You can actually feel when the tip hits the obstruction. If it feels mushy, it’s probably hair. If it feels solid, you might be hitting a pipe bend or a "solid" object like a toy. The trick with a hand auger is patience. If you force it, the cable kinks. Once a cable kinks, it’s basically garbage because it will never feed smoothly again.
Why the "Zip-It" Tool is Actually Brilliant
Before we get into the heavy stuff, we have to talk about the plastic hair snatcher. You know the ones—long, thin, barbed plastic strips. They cost about five dollars. Professionals sometimes scoff at them, but for a bathroom sink clogged with three years of shaving cream and hair? They are undisputed kings. You don’t even have to take the pop-up stopper out half the time. You just slide it in, wiggle it, and pull. It’s disgusting. It’s effective. It saves you from dragging a 10-pound drum auger into your bathroom.

The Toilet Auger (Do Not Use Anything Else)
This is the big one. If your toilet is backed up, do not—I repeat, do not—shove a standard drain snake down there. Standard snakes have thin cables with sharp, exposed coils at the end. They will leave ugly, permanent grey scratches on the bottom of your toilet bowl. These are called "crazing" or "chatter marks," and you can't just scrub them off.
A closet auger (the pro name for a toilet snake) is different. It’s a short, rigid pole with a "J" curve at the bottom. That curve is encased in a rubber or plastic sleeve. This sleeve protects the porcelain. The cable inside is much thicker than a sink snake—usually 1/2 inch—because it needs to push through heavy stuff. It’s only about 3 to 6 feet long. Why? Because most toilet clogs happen in the "trapway" of the toilet itself, not deep in the pipes. If a 6-foot auger doesn't clear your toilet, the problem is further down the line, and you’re looking at a main line issue.
Top-Handle vs. Floor-Based Power Snakes
When things get serious, we move to power. Power snakes take the manual labor out of spinning the cable.
Handheld Power Augers
These look like a hybrid between a drill and a drum auger. They’re great for 1-1/2 inch to 2-inch pipes. Think kitchen sinks and laundry lines. The motor provides consistent torque, which is way better at breaking up grease "slugs" than your shaky hand-cranking. Brands like Milwaukee and Ridgid have dominated this space lately with cordless versions. Being able to snake a drain without worrying about a power cord near a puddle of water is a massive safety win.
The Floor Machine
Now we’re talking about the "K-400" style machines. These sit on the floor. They have 50 to 100 feet of cable. If you have a floor drain in your basement backing up, or your bathtub is gurgling when you flush the toilet, this is what you need. These types of drain snakes are dangerous. If that cable catches on a root and you keep the motor running, the cable can "loop" back on itself and break your wrist in a heartbeat.

Professional plumbers, like the guys at Roto-Rooter, use machines with "sectional" cables or "continuous" cables.
- Sectional cables: You snap 10-foot pieces together. If one breaks, you only lose 10 feet. It’s easier to transport.
- Continuous cables: One long 100-foot piece in a drum. It’s cleaner because the mess stays in the drum, but man, those drums are heavy.
The Secret World of Flat Tape Snakes
You don't see these much in residential work anymore, but they’re cool. A flat tape snake isn’t a coil; it’s a flat strip of spring steel with a small spearhead. They are specifically for straight runs and very narrow pipes. They don't rotate. You just push. They’re almost exclusively used for clearing out small-diameter floor drains or older "sand traps" in garages. They don't have the "grabbing" power of a coiled snake, but they can push through sand or silt like nothing else.
What about the "Electric Eel"?
That’s actually a brand name, but it’s often used to describe any heavy-duty sectional pipe cleaner. These are the beasts used for 3-inch to 6-inch main sewer lines. If you have a maple tree in your front yard and your sewer is backing up, you need an "eel" with a C-cutter blade.
The blade literally saws through the tree roots. It’s a violent process. It sounds like a jackhammer inside your pipes. But it’s the only way to clear a root intrusion without digging up the whole yard. Note: This is not a DIY job. Renting one of these from a big-box store is possible, but without a slip-clutch or experience, you can destroy your main sewer line, especially if it’s older clay or Orangeburg pipe (which is basically tar-paper pipe—yes, that was a real thing in the 40s and 50s).
Choosing the Right Head for the Job
Most people think the end of the snake is just a "hook." It's not. If you’re renting a pro-level snake, you get a toolbox of attachments.

- The Boring Auger: Looks like a corkscrew. It’s for grabbing hair or wet wipes.
- The C-Cutter: Shaped like a "C" with teeth. This is for grease and soap scum. It scrapes the walls of the pipe.
- The Spade Cutter: A flat blade. This is for cutting through roots or solid blockages.
- The Arrow Head: For starting a hole in a complete blockage so the water can drain and you can see what you're doing.
Why Some Drains Just Can't Be Snaked
Sometimes, the types of drain snakes you use won't matter.
If your pipe has "bellied" (sagged), standing water will always collect there, catching debris. No snake fixes a sag. Or, if you have "scale" buildup in old cast iron—where the inside of the pipe gets crusty and narrow—a snake will just poke a small hole through the gunk. Two weeks later? Clogged again.
In these cases, you’re looking at "Hydro-Jetting." That’s essentially a pressure washer for the inside of your pipes. It uses 4,000 PSI to scour the pipe walls back to nearly new condition. It's expensive, but it's the "nuclear option" when snaking fails.
Actionable Steps for Your Next Clog
Before you go out and spend money, follow this logic tree. It’ll save you a headache.
- Step 1: The Plunge. Use a bellows-style plunger (the accordion looking one), not the flat "cup" plunger. If it’s a sink, plug the overflow hole with a wet rag first. No pressure, no progress.
- Step 2: The Zip-It. If it's a bathroom sink or tub, try the $5 plastic barbed strip. 90% of hair clogs live in the first 12 inches of the drain.
- Step 3: The P-Trap. Honestly, just take the trap apart. Put a bucket under the sink, unscrew the large slip nuts by hand (or with pliers), and just dump the clog out. It’s faster and more effective than any snake.
- Step 4: Identify the Snake.
- Toilet? Use a Closet Auger only.
- Kitchen Sink? Use a 1/4" or 5/16" Hand Drum Auger.
- Main Line/Floor Drain? Rent a 1/2" or 5/8" Power Floor Machine.
- Step 5: The "Feel." When using a snake, if you hit resistance, don't just ram it. Back it off, spin it, and move forward slowly. Let the tool do the work. If the cable starts to bow or twist under your hand, stop immediately—you’re about to kink the cable.
Always wear heavy-duty leather gloves. Do not wear thin rubber gloves; the rotating cable can catch the rubber and literally "wring" your finger into the machine. I’ve seen it happen. It isn't pretty. Safety glasses are also a must because when that cable comes out of the drain, it’s going to whip around and spray "black gunk" (a mixture of bacteria and old waste) everywhere, including your eyes.
Snaking a drain is a dirty, smelly, and weirdly satisfying job. Just make sure you're using the right tool for the specific geometry of your plumbing, or you’ll be making a very expensive "emergency Sunday" call to someone like me.
