Abstract
Abstract A plumbing fitting that is adaptable to be installed along any drain line so to permit the drain line to be easily and readily cleaned out in case it becomes clogged; the device consisting of a length of pipe having an internal screw thread at one end and an external screw thread at an opposite end for easy connection along the drain line, the length of pipe having a branch line extending from a side thereof and which is adaptable for receiving a clean-out rod or which may be attached to a hose, and a shut off valve cock being located along the main pipe so as to prevent back pressure up into a plumbing fixture such as a sink, tub or toilet.
