Abstract
A method for inserting a pipe into a socket and for removing the pipe out of the socket by making usage of a tool are provided herein. The pipe is retainable within the socket by teeth of a grip ring placed within the socket. In at least one embodiment, the method comprises (a) inserting the tool at least partly into the socket mouth into which the pipe is to be inserted, (b) extending the internal diameter of the socket mouth at least over a part of its circumference being smaller than the external pipe diameter when inserting the tool, (c) inserting the pipe into the socket mouth through a tool opening, (d) withdrawing the tool out of the socket, and (e) disengaging the tool from the pipe. Also disclosed herein are method elements for pipe withdrawal. The method elements in combination with the tool help avoid damage to the pipe.
