Abstract:
1. A drain line re-perforator method for punching holes in clogged drain pipe sections in a sewage disposal system, said re-perforator method comprising the steps of: providing a dual-actuating ram assembly formed of a cylinder and a piston rod and disposed concentrically within an outer cylindrically-shaped outer housing member; mounting hingedly three equally spaced-apart angled bracket members on the peripheral surface of the outer housing member and including a punch bit positioned for outward radial movement; positioning punch bits on the angled bracket members for outward radial movement; inserting the housing member and the ram assembly into the clogged drain pipe section; and moving said piston rod in a reciprocal motion from a retracted position to a an extended position so as to cause the angled bracket members to pivot outwardly and said punch bits to move outward radially for punching holes in the clogged drain pipe sections.
