Abstract: A three-way elbow for connection between a trap and a waste line is provided with a valved access ending in a plug. Removal of the plug allows attachment of a first end of a hose in its place. The second end of the hose is held above the water level of a sink by attachment to a board that fits over the sink. A snake inserted through the hose is directed by passageways in the elbow to the waste line. A container is mounted between a faucet for the sink and the second end of the hose so that disinfectant in the container can be carried into the hose. Brushes are mounted in the second end of the hose so as to aid in cleaning the snake as it is withdrawn.
