A rooter uses a long flexible cable to deal with your blocked drains. The rooter cable is simply fed down the line until it reaches the blockage. At that point, our plumbers will begin to chew up, push, or grab at the blockage to either remove it from the line, or push it out to the bigger city sewer pipe that can handle the obstructions size. A rooter has many different heads that can be attached to it for dealing with bigger blockages.
