The tool as per the present invention is formed by a handle, a handle shaft, a packing gland, a main body, a draining valve, and a gauge adapter or plug of wood, which is inserted by friction in the perforation to be blocked, forming a temporary seal therein while a definitive metal patch is fitted and soldered to the pipe. The invention also includes the method for safe removal of valves fitted to fluid pipes with said tool.
