The 30′ x 1/2″ Drain Cleaner clears lines from roof top to basement, including kitchen, bath and laundry. This electric drain snake can handle pipes from 1″ to 4″ in diameter when equipped with the right head. It comes with a ground fault circuit interrupter and a sealed air-activated foot switch for safe operation. Remember for best results try to have strait access into the blocked pipe. These units have an inner wire core and will not take 90° elbows or T’s. They will be able to maneuver around 45° bends and sweeps.
