ABSTRACT:
Apparatus and method for isolating and blocking articles flushed down toilets before they can get into and jam a main sewer line utilizes a threaded rod having a head for rotation thereof disposed on one end, a nut threaded onto the rod, a flat washer disposed next to the nut on the opposite side therefrom from the head, and a rubber washer disposed next to the flat washer on the opposite side therefrom from the nut. In a preferred embodiment, the rod is threaded into a threaded hole in a cleanout plug adjacent a toilet to be isolated and the nut tightens against the cleanout plug to compress the rubber washer to seal in sewer gases and fluids.
