Abstract
A method and apparatus for repairing a pipe system including a main pipe extending between a first and second manhole and one or more lateral pipes extending from the main pipe is provided. Aspects of the invention include the use of a main liner member having a plurality of lateral liner tubes in fluid connection and extending from the main liner member. The main liner member is used to line a main pipe, while the multiple lateral liner tubes extend into separate lateral pipes extending in various orientations from the main pipe. This method and apparatus provides for a single assembly to be able to line multiple pipes, which reduces time and cost for pipe repair.
