Electric drain snakes are among a plumber's best friends. These devices work by feeding a long coiled metal tube, called a snake, through your drain. The electric motor on these snakes helps them power through even the toughest clogs. The main thing to keep in mind when using an electric snake is that you have to tackle the clogs a little bit at a time. Just because it's electric, don't think you'll be able to clear everything out in one go.
