What’s the Difference Between a Drain Snake and a Drain Auger?


When our team got together to judge the 2018 Pro Tool Innovation Awards, some of our guys were surprised to see separate categories for drain snakes and drain augers. What’s the difference between a drain snake and a drain auger? Aren’t they the same thing?

Fortunately, we have Pros like plumber Scott Strollo to help sort out of these questions.

10-Second Summary

  • Drain snakes clear smaller lines, usually 1-1/4″ – 2″
  • Drain augers clear larger lines, usually 1-1/2″ – 3″
  • The tools basically function the same way

What’s the Difference Between a Drain Snake and a Drain Auger?

Functionally, the two tools aren’t much different. You have a drum to house anywhere from a few feet of cable all the way up to 100′ or more on some of the big machines.

You feed the cable into the drain and use a twisting action to either punch through the clog to loosen it or grab the clog to pull it out.

They can be hand crank, plug-in, or cordless. For many homeowners, having a drain snake on hand is worth it since they cost much less than a service call to your plumber. Even powered models like Ryobi’s hybrid drain auger are less than a service call. The first time you use it, it’s paid for itself.

Where these tools take different directions is in the size of the drain they’re designed to clear. Drain snakes are for smaller drains like your kitchen or bathroom sink. Drain augers tackle larger pipes like your toilet or shower drain. The snake covers lines from 1-1/4″ – 2″ range and you’ll use an auger for lines in the 1-1/2″ – 3″ range.

Other Differences Between a Drain Snake and a Drain Auger

You’ll notice that drain snakes usually have a smaller diameter cable than a drain auger. Since both clean by twisting the accessory at the tip, the auger needs a stouter cable to help it torque through the clog.

Likewise, cable tips don’t look terribly different between the two drain clearing tools, but auger tips can be larger to twist into and through clogs that take up more space.
