Abstract
A method and an apparatus for use in installing a liner in a conduit as part of a repair procedure, the apparatus including a sealing inlet port (106) for passage of the tubular liner (72) into an enclosed container (52) where an increased pressure is maintained to move the tubular liner into the conduit (179) and to evert it as it moves along the conduit. A clamp (80) holds one end of the liner to the outlet side of an everter box (50) supported on a frame (18) that may be mounted on a trailer hitch receptable. The sealing inlet port includes a pair of lips (112, 114) to press against the opposite sides of a flattened liner. Support members (148, 150) keep the lips from being forced back out toward the outside of the pressurized everter box and control friction between the lips and the liner. Inlet and outlet fittings are provided. The apparatus is portable on a trailer hitch receiver.
