Abstract: A device for repairing pipe leakage takes the form of a short section of PVC pipe with fittings. The pipe is ideally a 1?-2? section fashioned into a U-bend with a substantially semi-circular bend and two arms, and the fittings take the form of an elbow joint glued onto each arm. The arms are ideally offset up to 5° from parallel. A method of repairing cracked PVC piping using the device involves cutting out a 4?-6? section of piping, gluing the exposed ends of the broken piping as well as the elbow joints, squeezing the U-bend, positioning the squeezed device into the gap in broken piping, and releasing the U-bend to fit the elbow joints over the exposed ends of broken piping. The device has no vulnerable moving parts or O-rings, and it obviates the need to remove entire pipes.
