Abstract: A locating appliance provides expedite locating of non-metallic pipes. The locating appliance is employed with an existing tight seal plug inherent to a non-metallic pipe and includes a metal disk engaged with a self-taping screw. The locating appliance is installed by suitably screwing it into an end cap of the existing tight seal plug. Alternatively, a locating plug including a metal disk affixed with the end cap of the plug, is designed to be installed instead of the existing tight seal plug inherent to the non-metallic pipe. When a user has a need to access the pipe, such as for replacement purposes, to clear a sewer line, or the like, the user is able to quickly and accurately locate the locating appliance, or the locating plug using any suitable metal detector or device known in the art.
