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.
