Drain Cleaning
Drain snaking
Short answer
Drain snaking uses a rotating steel cable with a cutting or retrieving head to break through or pull out a blockage. It's the fastest way to open a single clog in a sink, tub, toilet or main line, but it doesn't clean the pipe walls, so buildup that coats the pipe tends to return.

- Next step if it recurs
- Camera inspection or hydro jetting.
Types of drain snakes
| Tool | Typical reach | Used for |
|---|---|---|
| Hand auger | About 15–25 ft | Bathroom sinks, tubs, shower drains |
| Closet (toilet) auger | 3–6 ft | Toilet traps; has a guard to protect the porcelain |
| Drum machine | Varies by size | Kitchen lines, laundry, smaller main lines |
| Sectional machine | Long runs, added in sections | Main building drains and sewer laterals |
What the cutting head does
The head on the end of the cable is chosen for the clog. Spiral heads grab hair and wipes so they can be pulled out. Spade and saw-tooth blades cut through packed debris and roots. Wider blades are used on larger pipe so the cable cleans more of the pipe's diameter.
Should you snake a drain yourself?
A hand auger through a sink or tub drain is a reasonable homeowner job. Power machines are a different matter. A cable that kinks or wraps can cause serious hand injuries, and an aggressive head can damage fixtures, older pipe, or a toilet's glazed trap.
- Reasonable DIY: a hand auger through a sink or tub; a closet auger in a toilet.
- Call a plumber: main line clogs, clogs you can't reach from the fixture, anything involving a power machine, or sewage coming up from a lower drain.
Why a snaked drain can clog again
A snake opens a path about the width of its head. In a pipe coated with grease or scale, the remaining buildup narrows the line and catches new debris. Roots that were cut grow back from the same joint. If a line needs snaking more than once or twice a year, the next steps are a camera inspection to see why and, if the pipe is sound, hydro jetting to clean it fully.
Problems that lead to drain snaking
Common questions
Can a drain snake damage pipes?
Used correctly on sound pipe, rarely. Damage happens with the wrong head on old or thin pipe, forcing a cable around a tight fitting, or using a sink auger in a toilet, which can scratch the porcelain.
Is snaking or plunging better for a toilet?
Try a flanged plunger first. If it doesn't work, a closet auger is the next step, because it's designed to protect the bowl.
