ABSTRACT:
A conduit structure including a first conduit pipe in fluid communication with a second conduit pipe. The first conduit pipe is defined by a first axis, with a bull head pipe extending beyond the second conduit defined by a third axis parallel to and offset relative to the first axis of the first conduit to accommodate debris and abrasive material minimizing damage to the elbow association of the first and second conduit. A modification of the invention includes the use of a modified bull head pipe, including a manually reciprocatable piston mounted within the pipe to effect periodic discharge of debris accumulated within the modified bull head pipe.
