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.

Abstract: A packer apparatus for the internal sealing of pipe leaks having a cylindrical structure and a single sleeve located on the exterior of the cylinder. The single sleeve has a pair of inflatable chambers connected together in spaced relationship to each other and air hoses connect through the cylinder to each of the inflatable chambers for inflating and deflating the chambers remotely with air pressure. Chemical lines are connected through the cylinder and through the sleeve between the inflatable chambers. The cylindrical structure is made of two or more segments and is collapsible for reducing the size of the packer. The single sleeve is made of rubber reinforced with tire chord and is held to the cylinder only by the connections with the chemical and air lines.
