ABSTRACT:
A drain clearance device comprising a length of flexible hose having at one of its ends means for connecting it to a source of water under pressure and at the other end a nozzle of elliptic contour longitudinally thereof and of a size to fit into a drain pipe. Said nozzle has four circumferentially spaced, slot-shaped orifices in the flanks of its rounded front end that are adapted to emit flat jets of water under increased pressure forwardly at an oblique angle against the inner surface of the drain pipe to dislodge and flush away any foreign matter that may have accumulated on the wall of the pipe and impede the free flow of water through the pipe. Intermediately of its ends the hose carries slidably mounted thereon means that may be manipulated to close the space around the hose to block back flow of water to the entrance opening of the drain during operation of the device.
