ABSTRACT:
A quick, lightweight cartridge puller for hot and cold water mixing valves operates to provide an increased mechanical force advantage while applying opposed relative forces between a valve cartridge and its value housing to avoid stressing wall and decorative material supporting the valve housing. The puller includes a clamping assembly that securely and positively engages the cartridge, a draw screw, an outer body member slidably receiving the draw screw and transmitting a reactive force to the valve housing and a puller nut which is tightened onto the draw screw to create an extremely high pulling force which quickly and easily extracts the cartridge from the housing.
