Abstract
A system for stopping flow in a pipe with a plug positioned in the pipe to allow for repairs of the pipe. The plug comprises a body with an inflatable or compressible member, and a cap and connector valve on the body. An inflation line with a coupling connects to the valve for blocking off and sealing a damaged area of the pipe. An inflation line is used to deposit and retrieve the plug within the pipe before and after a repair is made.
