Connection between a lateral and main pipe and method for making same

摘要

Apparatus and method for connecting a lateral pipe to a main pipe are provided by a tool having a first end within the main pipe and a second end outside the lateral pipe so as to apply pressure to the below-ground connection of the main and lateral pipes from an above-ground location. The entire operation may be done without a person having to enter into an access opening in the ground to connect the lateral pipe to the main pipe. A laser is used to determine the depth of the access hole relative to the surface of the ground and the main sewer pipe.
