Unfortunately, clogged plumbing is an inevitable part of having a plumbing system in your home—you can’t escape it. That’s why you must learn how to snake a drain.

Cons of Snaking Drains

While using a drain snake to unclog your drains has its advantages, it also has its cons, some of which are it:

  • Can’t clear some types of clogs. Some clogs may need a tool that can grab them to dislodge them effectively. A snake can’t do that.
  • May leave some debris. Especially if the drain snake is smaller in diameter than the pipe you’re cleaning, it can leave some material clinging to the pipe walls. This could cause more buildup of the stuff that blocked your drain in the first place.
  • Can’t always clear clogs. While a drain snake is a great tool for clearing clogs, some blockages may be too dense or extensive for the drain pipe.

  • Main drain
  • Tub drain
  • Shower drains
  • Bathroom sink drains
  • Washing machine drains
  • Kitchen drains

Before you start snaking your drain, follow the pipes to understand how they go and how you’ll need to maneuver your drain snake.

How to Snake a Drain

So how do you snake a drain?

Here are a few steps you can take to ensure that you succeed at unclogging your drain using a drain snake:

Gain Access to the Drain

To gain access to the drain line, you can start by removing the appropriate covering part. You can use a regular wrench, pipe wrench, or tongue-and-groove pliers, depending on the drain type. If applicable, remove the cleanout plug from the drain line.

To get access to your drain:

  • For a sink drain, remove the drain stopper or the P-trap.
  • For a tub drain, remove the overflow assembly.
  • For a washing machine drain, remove the washer drain hose from the drain standpipe.

Prepare the Snake and Begin Snaking

Woman washing hands in sink With rubber gloves on, loosen the set screw on the drain snake. Doing so allows you to pull out the cable freely. Insert the snake into the drain and slide the cable in until it meets resistance. This could be the clog itself or simply a bend in the pipe. Tighten the set screw to clamp down on and apply just enough pressure to keep it from turning.

If it’s a bend, crank the snake handle clockwise while applying moderate pressure on the cable to work it into the drain. Continue until you feel the cable move past the bend.

Continue Snaking

Once you’ve passed the bend in the pipe, loosen the set screw and feed the cable by hand until it meets resistance again. If you feel like the drain snake has reached the clog, hook onto the clog by turning the snake. You can then pull the snake back up by loosening the set screw and pulling the cable back into its housing. It’s advisable to run the snake through a rag to keep the cable and housing clean. Repeat the process to ensure you’ve cleared your drain of every bit of debris.

Flush the Drain

Reinstall whatever you had removed and flush the drain with a full flow of water. For a washing machine drain, you can run a small rinse and drain cycle. Watch the drain carefully to ensure that the operation was a success and that the water is draining.
