The trenchless water pipe replacement device includes a cable pulling device, a pipe splitter, a length of cable and a cable end piece. The cable is fished through a pipe that is to be replaced, and a length of replacement pipe is attached to the end piece. The pipe splitter is disposed at the front end of the pipe and the cable pulling device is disposed behind the pipe splitter. When the cable pulling device is activated, the end piece makes contact with the rear end of the pipe and sufficient pulling force is applied to the cable to dislodge the pipe and pull it onto the pipe splitter, which splits the pipe as it is pulled from the ground. The replacement pipe is pulled behind the end piece, such that when the end piece is entirely pulled through the ground, the replacement pipe is disposed in its place.
