Plumbers have several different tools and techniques at their disposal for drain cleaning. A common method used by plumbers is a drain auger or drain snake. This long, flexible rod is used to manually break up clogs and push them through the drain pipe.
Another popular tool for drain cleaning is a mechanical plunger or air venturi. Plunger heads attach to a hose, are inserted into the drain, and quickly pump to create suction. This method is useful for breaking up stubborn clogs in sinks and tubs.
