Patent ID: 7425024

Claim:
A single piece polyvinyl chloride (PVC) drop pipe that has lateral strength when connected to a similar adjacent PVC drop pipe, said PVC drop pipe comprising: a male end having external threads; a female end having an enlarged exterior diameter; an intermediate section between said male end and said female end having a uniform interior diameter; a first section at said female end having an interior diameter which is slightly larger than the outer diameter of a male end of said similar adjacent PVC drop pipe to receive said male end of said similar adjacent PVC drop pipe therethrough; a second section at said female end having internal threads to mate with said external threads of said male end of said similar adjacent PVC drop pipe, wherein said mating creates a watertight connection; said first section positioned to funnel said male end of said similar adjacent PVC drop pipe to said second section and being long enough to provide lateral strength when said PVC pipe is connected to a similar adjacent PVC drop pipe; said second section being positioned between said intermediate section and said first section; said PVC drop pipe being disconnectable from said similar adjacent PVC drop pipe and reusable for watertight transfer of fluids.
