A pipe system purging assembly (10) is adapted for connection to a blocked pipe system (12) for the purpose of eliminating or reducing blockage therein. The preferred embodiment of the purging assembly (10) includes a internal tubing system (16) which is connected to the blocked pipe system (12) by an adaptive connector (14). A shock producing subassembly (20) then delivers rapid and repeated hydraulic shocks through the fluid into the blocked pipe system (12). Alternate subassemblies for enhancing the operation of the assembly (10) include a backpump subassembly (34), a fluid input subassembly (36) and a visual inspection subassembly (42). An inventive method of purging blockage from pipe systems is also provided with the steps of filling the isolated pipe system with fluid and delivering repeated hydraulic shocks thereto for the purposes of dislodging the blockage. Direct physical shocks may also be provided to the pipe system (12). The pipe system purging assembly (10) and the method for use thereof are particularly well adapted for use in extensive piping systems such as those found in large building complexes.
