A plumbing snake is a flexible auger used to remove clogs in pipes that cannot be removed with a plunger. Most snakes contain a coiled metal wire with space between the coils at the end. The other end is attached to a device with a crank that rotates the wire as it moves down into the pipe.

The auger end of the wire digs into the clog much like a corkscrew, allowing recovery of the item creating the clog when the snake is pulled out. Also, a clog can be removed when the end of the snake breaks up the clog, permitting it to pass through the drain. Before using a plumbing snake, it is important to understand how to use one.

The following is a guide on how to use a plumbing snake:

1. Set Up: Before using a plumber's snake, make sure you have towels and a bucket to collect any water that may run over on the floor. Put on gloves because the snake cable can get dirty and slimy.

2. Access the Drain: Remove the drain cover

3. Feed in the Plumbing Snake: Start with the smallest snake that you have. If it does not work, use a larger one. Feed the snake's head into the drain. Rotate it a bit in a clockwise direction as you slide it through the pipe. Be careful not to damage sinks, toilets, and pipes.

4. Locate the Clog: Keep feeding in the snake while rotating until you hit the blockage. Keep repositioning the grip within a couple of inches of the entry way to the pipe as you feed the snake into the drain.

If you cannot locate the obstruction, run the snake in through the branch pipe. If there does not seem to be a clog in the branch pipe, the blockage may be in the main waste and vent stack, or in the sewer line. You will have to call a plumber.

5. Collect the Clog: Once you have reached the blockage, rotate the head of the snake until you can feel it latch on to the clog. Once you have a good hold, withdraw the snake out of the drain. You can also push the snake and chew away at the clump until the snake is driven through it. If it is a thick and solid clump, then use the snake to gnaw away at the clog. When you pull the blockage back, it may start to become messy. This is where a bucket and towels becomes necessary.

6. Eliminate Remaining Debris: You will have to get rid of the remaining pieces in the drain. You can do this by running hot water down the drain for a few minutes to wash away any remaining debris.

Plumbing snakes are a great tool to unclogging a drain. Used properly, it can help you avoid an expensive plumbing bill.
