ABSTRACT:
A drain line re-perforator device for punching holes in clogged drain pipe sections in a sewage disposal system is provided. The re-perforator device includes an outer cylindrically-shaped housing member and a dual-actuating ram assembly disposed concentrically within the outer housing member. Three equally spaced-apart angled bracket members are mounted hingedly on the peripheral surface of the outer housing member and includes a punch bit positioned for outward radial movement. The ram assembly is formed of a cylinder and a piston rod. The piston rod is moved 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 the punch bits to move outward radially for punching holes in the clogged drain pipe sections.
