How to Use a Plumbing Snake (Drain Auger)
A plumbing snake, also called a drain snake or drain auger, is a flexible coiled cable you feed into a pipe to reach a clog a plunger cannot move. You turn a handle so the tip rotates, then either chew through the blockage or hook it and pull it out. The right snake depends on the drain: a small hand auger for sinks and tubs, a closet auger for toilets, and a powered drum machine for main lines.
What a plumbing snake actually is
A plumbing snake is a length of tightly wound steel cable with a spring or hook at the tip, wound onto a handle, drum, or reel. Turning the handle spins the cable so it corkscrews past the bends in a drain and works into the clog. It reaches blockages 5 to 25 feet down that a plunger, hot water, or an enzyme cleaner never touch.
Reach for it after the simpler fixes fail. If you have not already, try a plunger and other methods first, because a snake is messier and takes more care. A snake belongs to the homeowner tool kit once you have a drain that clogs more than once.
The types of plumbing snake
There are four common types, and they are not interchangeable. A hand auger handles most sink and tub clogs, a closet auger is the only safe choice for toilets, a drum auger adds reach and a crank drum, and a powered drum machine is for deep or main-line blockages. Match the tool to the drain before you buy or rent.
| Type | Best for | Typical cable length | Power | Price to buy |
|---|---|---|---|---|
| Hand auger (drum snake) | Sink, tub, shower drains | 15 to 25 ft | Manual crank; some accept a drill | $15 to $40 |
| Closet (toilet) auger | Toilets only | 3 to 6 ft | Manual crank | $15 to $40 |
| Drum auger, heavy hand | Longer branch and floor drains | 25 to 50 ft | Manual crank, larger drum | $40 to $90 |
| Powered drum machine | Main line, tree roots, grease | 50 to 100 ft | Electric motor | $200 to $1,000+ (usually rented) |
Prices reflect August 2026 US hardware and home-center listings and vary by cable length and build quality. For the powered end of that table, the powered drain machines we tested break down which motor and cable size suit which job.
Match the snake to the drain
Picking the wrong snake either wastes money or damages the fixture. A bare-cable hand snake cracks toilet porcelain, and a short closet auger cannot reach a kitchen clog behind the wall. Use this pairing before you start.
- Bathroom or kitchen sink: hand auger, 15 to 25 ft. The clog usually sits in or just past the P-trap.
- Tub or shower: hand auger, 15 to 25 ft, fed through the overflow plate or the drain after removing the stopper.
- Toilet: closet auger only. The curved sleeve protects the bowl and the trap.
- Floor drain or long branch line: heavy drum auger, 25 to 50 ft.
- Main sewer line, roots, or repeated whole-house backups: powered drum machine, 50 to 100 ft, or a plumber.
How to use a plumbing snake, step by step
Snaking a sink, tub, or shower with a hand auger takes about 30 minutes. Work slowly, keep the cable turning, and never jam it forward. The rotation, not force, is what clears the clog. Keep a bucket and towels close because the cable comes back dirty.
- Gear up and set up. Put on tight-fitting rubber gloves and safety glasses, and set a 5-gallon bucket under the trap. If you poured chemical drain cleaner earlier, flush with water and wait, because the cable will fling caustic splash back at you.
- Open the drain. Remove the stopper, strainer, or overflow plate so the cable has a clear path. For a sink you may get a cleaner shot by removing the P-trap under the cabinet and feeding the snake straight into the wall pipe.
- Feed the cable in. Push the tip into the drain and turn the handle clockwise as you go. Let the cable find its own way through the first bend. Do not force it.
- Work through the curves. At each turn, crank harder or gently wiggle the cable while you keep rotating. Steady turning walks the tip around the elbow.
- Break up the clog. When you feel resistance, hold light forward pressure and keep rotating so the tip either chews through the blockage or hooks it. A soft, giving resistance is the clog. A hard dead stop is usually the pipe wall or a fitting, so back off.
- Retrieve the cable. Crank the handle to wind the snake back out slowly, wiping gunk off the cable into the bucket as it comes. The clog often comes with it as pieces or a mass.
- Flush and test. Run hot water for two to three minutes to carry away loosened debris and confirm the drain runs freely. Reinstall the trap, stopper, or overflow plate.
- Clean the cable. Wipe it down, dry it, and store it coiled so it does not rust. A rusted cable snags and can snap inside a pipe.
How to use a closet auger on a toilet
A toilet needs its own tool. A closet auger has a curved metal guide tube that steers the cable through the toilet trap without scratching the porcelain, plus a short 3-foot cable sized for the job. Never substitute a bare sink snake.
- Pull the cable up so only the curved tip shows, then set the tip into the bowl pointing down into the drain opening.
- Hold the guide tube steady and crank the handle clockwise to drive the cable into the trap.
- When you hit the clog, keep turning to break it up or hook it, then reverse the crank to withdraw the cable.
- Flush once to confirm the bowl drains, and watch that the water level does not rise toward the rim.
Snake safely, and know the limits
Most snaking damage comes from force and from powered tools in the wrong hands. Feed slowly, let rotation do the work, and stop pushing at a hard dead stop. Wear gloves and eye protection, because the cable slings drain water and any leftover chemical cleaner.
Powered drum machines multiply both the reach and the risk. The motor can whip the cable, catch a glove or sleeve, or punch through a weak old pipe. If you rent one, keep the cable turning slowly, feed only a few feet at a time, and never run it in fragile clay or cast-iron drains you are unsure about.
Rent or buy: the dollar math
The decision comes down to how often you will use it. A hand auger is cheap enough that a single rental costs about the same as owning one outright, while a powered machine is a rental for most homeowners. Renting runs about $20 to $40 per day for a handheld and $75 to $150 per day for an electric machine, depending on cable length.
| Situation | Best move | Rough cost |
|---|---|---|
| Sink or tub clogs more than once a year | Buy a hand auger | $15 to $40 once |
| Any toilet that clogs | Buy a closet auger | $15 to $40 once |
| One-time deep branch clog | Rent a handheld or drum snake | $20 to $40 per day |
| Main-line or root blockage, one time | Rent a powered machine | $75 to $150 per day |
| Repeated main-line backups | Call a plumber | See pro pricing below |
If the clog keeps coming back or sits in the main line, buying more cable is throwing money at a symptom. Compare the rental math against what a pro charges to clear a drain before you commit a Saturday to it.
When to stop snaking and call a plumber
Call a professional when snaking stops working or points to a bigger problem. Warning signs include a clog that returns within days, several drains backing up at once, gurgling or sewage smell, or 25 feet of cable that never reaches the blockage. Those often mean a main-line or sewer issue a hand snake cannot fix.
A pro brings a longer powered machine and a camera to find the cause, whether that is roots, a belly in the line, or a collapse. In many areas a professional drain clearing runs roughly $145 to $300 for a straightforward job, and more if the line needs a camera inspection or excavation, depending on your region and the access to the pipe.
Frequently asked questions
What is the difference between a drain snake and a drain auger?
They are the same tool. “Plumbing snake,” “drain snake,” and “drain auger” all name a flexible coiled cable you feed into a pipe to break up or hook a clog. Some brands reserve “auger” for the toilet (closet) version, but in a hardware aisle the terms are used interchangeably.
Can you use a regular drain snake in a toilet?
No. A standard drain snake has bare cable that scratches porcelain and can crack the trap. Use a closet auger (toilet auger) instead. It has a curved metal sleeve that guides the cable through the toilet trap without touching the bowl, and a shorter 3-foot cable sized for that job.
Can a plumbing snake damage your pipes?
It can if you force it. Bare cable driven hard against a joint, an old trap, or PVC can gouge or crack the pipe. Feed slowly, let the rotating tip do the work, and stop pushing the moment you feel a hard stop rather than resistance. Never run a powered snake in fragile old drain lines.
How far should you push a drain snake?
Push until the tip reaches the clog, which is usually 5 to 15 feet for a sink, tub, or shower and often near the P-trap or the branch line behind the wall. If you have fed 25 feet without hitting anything, the blockage is likely deeper in the main line and needs a longer machine or a plumber.
Should you rent or buy a plumbing snake?
Buy a $15 to $40 hand auger if you snake a drain more than once a year, since one rental costs about the same. Rent a powered drum machine ($75 to $150 per day) for a one-time deep or main-line clog you would otherwise never reuse. A closet auger is cheap enough ($15 to $40) that most homeowners just buy one.
