A drain snake, also called a hand auger, is a flexible cable designed to reach a blockage that a plunger cannot clear. The right type depends on the fixture, drain size and nature of the obstruction. Choosing equipment that is too large or using it aggressively can damage a fixture or pipe, so start with the simplest safe method.
Common types of drain snakes
1. Plastic hair-removal tool
A short, barbed plastic strip can pull hair and soap residue from just below a bathroom sink or tub strainer. It is inexpensive and easy to use, but it only reaches shallow clogs. Wear gloves and dispose of removed debris hygienically.
2. Small hand-crank sink auger
A compact hand auger is designed for some sink and tub drains. Its cable advances through the drain to reach a blockage beyond the opening. Follow the tool instructions and avoid forcing the cable around tight bends.
3. Toilet auger
A toilet auger has a protective sleeve and a shape designed to pass through the toilet trap while helping protect the porcelain. Do not use an ordinary exposed metal snake in a toilet because it can scratch the bowl.
4. Professional drain machine
Powered drain machines are intended for larger or more difficult lines and require training, protective equipment and an understanding of pipe condition. They are generally not a good first purchase for routine homeowner use.
How to decide what you need
- Hair near a tub or shower strainer: a plastic hair-removal tool may be enough.
- A slow bathroom sink: first clean the stopper and accessible trap; a small hand auger may help if the obstruction is farther down.
- A clogged toilet: use a toilet plunger first, then a toilet auger designed for the fixture.
- Several fixtures backing up: this may indicate a branch drain or main sewer issue; contact a plumber rather than repeatedly snaking individual fixtures.
Safe steps for using a small hand auger
- Read the manufacturer’s instructions and put on gloves and eye protection.
- Protect nearby surfaces and remove standing water where practical.
- Insert the cable carefully, keeping the tool aligned with the drain.
- Advance slowly; rotate only as directed and never force resistance.
- Withdraw the cable carefully and clean it according to the product instructions.
- Run water gradually to check drainage. Stop if water backs up or the blockage remains.
What not to do
Do not use a drain snake after pouring chemical cleaner into the drain; splashback can cause serious chemical burns. Do not force a cable through a suspected broken, fragile or corroded pipe. Avoid using a toilet auger on a sink or a sink auger on a toilet. Never use a tool to investigate a drain that may contain hazardous material.
When a professional is the better choice
Repeated clogs, sewage odors, gurgling across multiple fixtures, water backing up into a tub when a toilet flushes, or a blockage that returns quickly can point to a deeper drainage or sewer problem. A plumber can inspect the line and determine whether cleaning, repair or a camera inspection is appropriate.
Frequently asked questions
Will a drain snake damage pipes?
Incorrect size, excessive force or unsuitable equipment can damage pipes. Use a tool designed for the fixture and stop if you encounter unusual resistance.
Is a drain snake better than chemical cleaner?
For some physical obstructions, mechanical removal may be more appropriate. Chemical products have specific hazards and are not suitable for every pipe or blockage.
How often should I snake a drain?
A drain in good condition should not need routine snaking. Repeated need for a snake is a sign to investigate the underlying cause.
