A drain snake, also called a hand auger or plumbing snake, is a tool used to clear clogs inside sink, shower, tub, and floor drains. It has a long flexible cable that feeds into the drain and either breaks up the clog or hooks debris so you can pull it back out.
For many homeowners, a drain snake is the next step after a plunger does not work.
How a Drain Snake Works
A basic hand auger has:
- Flexible cable — feeds into the drain line
- Auger tip — grabs, breaks up, or pushes through the clog
- Drum or housing — stores the cable
- Handle or crank — rotates the cable
- Thumb screw or lock — holds the cable while you crank
As the cable moves through the drain, you rotate it to help the tip move through bends and work into the clog. Depending on the blockage, the snake may pull out hair, break apart buildup, or push the obstruction farther into the larger drain line.
What a Drain Snake Is Used For
Drain snakes are commonly used for:
- Bathroom sink clogs
- Shower drains
- Tub drains
- Laundry drains
- Kitchen sink clogs after the trap has been checked
- Hair and soap buildup
- Small objects close to the drain opening
They are especially helpful when the drain is slow or completely stopped and the clog is beyond the visible drain opening.
What a Drain Snake Is Not For
A regular hand drain snake is usually not the right tool for:
- Toilets — use a closet auger instead
- Main sewer line backups
- Tree roots
- Collapsed or damaged pipes
- Multiple fixtures backing up at once
- Drains with standing sewage
- Situations where water is backing up into tubs or floor drains
Those are signs the clog may be deeper or more serious.
How to Choose a Drain Snake
For hair near the drain opening
Use a plastic hair removal tool.
Best for:
- Bathroom sinks
- Shower drains
- Tub drains
- Hair just below the stopper or strainer
Why:
- Cheap
- Easy to use
- Good first step before using a metal auger
For most household sink and tub clogs
Use a 15- to 25-foot hand drum auger.
Best for:
- Bathroom sinks
- Shower drains
- Tub drains
- Small household clogs
Why:
- Long enough for common drain clogs
- Easier to control than a power machine
- Affordable for homeowners
For deeper or tougher clogs
Use a powered drain auger or rent a drain cleaning machine.
Best for:
- Longer drain runs
- Tougher clogs
- Repeated clog issues
Caution: powered machines can damage pipes if used incorrectly. If the pipe is old, fragile, or unknown, get advice before using one.
For toilets
Use a closet auger, not a regular drain snake. A closet auger has a protective tube and design that helps avoid scratching the toilet bowl.
How to Use a Drain Snake
Remove the stopper or strainer Give the cable the clearest path into the drain.
Feed the cable slowly Push the cable into the drain until you feel resistance.
Lock the cable Tighten the thumb screw or cable lock.
Rotate the handle Turn the crank while applying light forward pressure.
Work the clog Push and pull gently while rotating. Do not force the cable hard.
Retract the cable Pull it back slowly. It may bring hair or debris with it.
Flush the drain Run water to test whether the drain clears.
Common Mistakes
Using a regular drain snake in a toilet It can scratch porcelain and may not navigate the toilet trap correctly.
Forcing the cable Too much force can kink the cable or damage the pipe.
Ignoring the P-trap For sinks, the clog may be in the trap right under the sink. Sometimes removing and cleaning the trap is easier.
Using chemical drain cleaner first If the chemical does not work, you may now be snaking through caustic water. That is dangerous for your skin and eyes.
Not cleaning the cable after use Drain cables get gross quickly. Wipe and dry the cable before storage.

Fixers Club Tip
If one drain is slow, a hand auger may be a good DIY move. If multiple drains are backing up, or a tub fills when the toilet flushes, stop and ask for help. That can point to a main line issue, not a simple sink clog.
