ABSTRACT:
An apparatus for installing a liner within a service pipe having an access end and a terminal end wherein the terminal end is transversely connected to a main pipe for allowing fluid to flow therebetween. The apparatus includes a flexible tubular member having a leading end and a trailing end. The leading end includes a flexible retainer secured thereto for being positioned within the main pipe proximate the service pipe terminal end. The flexible tubular member is impregnated with a thermosetting resin which cures after the flexible tubular member is positioned within the service pipe. Guiding and forcing members are provided for positioning the flexible tubular member within the service pipe such that the flexible retainer is seated within the main pipe proximate the service pipe terminal end and the trailing end is positioned proximate the service pipe access end. An inverted flexible tubular conduit is positioned within the flexible tubular member and filled with a fluid for forcing the flexible tubular member radially outwardly into engagement with the service pipe and for aiding the curing of the resin.
