Plumbers' Helpers, also known as drain SNAKES, are tools used by plumbers to clear clogged drains. They consist of a long, flexible metal cable with a cutting head on one end that is inserted into the drain and then manipulated to cut through the blockage. The cutting head is usually powered by an electric motor, but manual versions are also available. SNAKES are an essential tool for plumbers, allowing them to quickly and effectively clear clogged drains without having to resort to more invasive methods.
