Most clogged drains can be easily repaired without too much trouble. However, if multiple drains are clogged throughout the house, then the issue could be with the main sewer line. In this case, you will need a plumber to come out and clean it for you. They will use a sewer snake to do this. They will be able to get it working like new, and you can even have this service performed regularly to prevent the clogs in the future.
In this video, you will learn how to use a sewer snake to clean the main sewer line.
There are different ways to get into the main sewer line, but most houses have an opening just outside on their lawn. The sewer snake is motorized and controlled by a machine. It gets sent down the line and will cut through the debris that is down there. The snake is flexible and can reach all the crooks and crannies of the line.
