Abstract
Pipe leak method and apparatus are provided in which the apparatus includes a pair of inflatable sleeves having each end of each sleeve sealed and connected by a flexible connection in spaced relationship to each other. One sleeve has a fluid connection for directing air thereinto for inflating the sleeve and a connection between the sleeves allows both sleeves to be inflated simultaneously from a remote location. A chemical line is connected through one sleeve to a space between the sleeves for directing several chemicals into the space when the sleeves are inflated in a pipe to seal a leak in the pipe between the inflated sleeves. The method has a TV camera located in a sewer line adjacent to a connection with a second sewer line so that the operator can remotely view the intersection to determine if fluids infiltrating the second line are flowing into the intersection. The packer is inserted into the second pipe and inflated at a plurality of locations along the pipe to determine which location stops or reduces the flow of fluid into the intersection being observed with the TV camera, then repairing the located leak with the packer apparatus.
