Heavy-duty power snake used for unclogging the main drain pipes of a house (sewer and storm water pipes). Can unclog 3 inch diameter pipes and larger (cannot go smaller). Comes with 4 possible heads for the end of the snaking cable. WARNING: This tool is extremely large, heavy, and physically challenging to handle not only in transport but also while using it. We highly recommend planning for 2 able-bodied adults to both transport and use the tool. The cable is heavy and dangerous - please use caution while snaking your drain - keep loose cloth away from the cable - do not use cloth gloves while handling the cable (thick leather or rubber only).
