Abstract
The present invention is directed to a method for making service connection to polyethylene replacement sewer pipe. Specifically, the method involves the steps of (1) locating the service; (2) excavating an opening less than two feet in diameter from the surface to the polyethylene replacement pipe at the service; (3) introducing a fusing apparatus on top of the polyethylene pipe and fusing a stack to the polyethylene pipe; and (4) drilling a opening into the polyethylene pipe through the fused stack. Before drilling the opening into the polyethylene pipe, the stack may be tested to make certain that there are no leaks in the fusing step and that the stack is securely connected to the polyethylene pipe.
