Abstract: A submersible pump drop pipe and casing assembly and method of manufacture is disclosed. The drop pipe/casing has a seated connector and base. The seated connector has a first and second sections, the first section being used to align and direct the base into the seated connector and to provide lateral strength to the pipe.

Abstract: A novel design for the connection of lengths of polyvinyl chloride (PVC) casing. Each length of casing has a male end and a female end. The female end has a narrowing interior diameter with its wider interior diameter at its outermost end sufficient to receive the male end of similar length of casing for connection. The diameter of the female end narrows to a diameter which is less than the outer diameter of the male end. The male end has a lip at its leading edge and is slotted and compressible when forced through the narrowed diameter of the female end. A groove in the interior surface of the female end is sufficient to receive the lip at the leading edge of the male end. When the lip at the leading edge of the male end reaches the groove, it allows the compressed male end to expand with the groove receiving the lip therein. The connected lengths of casing are locked together in this manner.
