Abstract: An apparatus for replacing underground plastic pipe consisting of a mole, flexible cable, pulling devise and water pump. The mole is a cone shaped tool consisting of a nose section, cutting blades, water nozzles and a hose barb. The flexible cable is inserted through the existing pipe, one end is attached to the pulling devise and the other end is attached to the nose section of the mole. Replacement pipe is attached to the hose barb section of the mole on one end and to the water pump on the other end. As the pulling devise pulls the mole along the path of the existing pipe, the cutting blades split the existing pipe and water from the nozzles erode and moisten the soil surrounding it. The cone shape of the mole expands the split pipe out into the moistened soil, creating clearance for the new pipe being pulled into place.
