How can a blockage in the drain be removed?
Generally property owners call a plumber/drainage contractor or try to remove the blockage themselves with rented equipment. Drain repair equipment can include electric eels (i.e., power snake) or sewer rods with an appropriate size cutter on the end that is inserted into the drain through a cleanout. Many plumbers/drainage contractors have video-inspection equipment that can be used to identify problems within a drain. Video inspection equipment is not suitable to remove a blockage.
