ABSTRACT:
An apparatus and a method for cleaning the open perforations in a well and for bailing a well. The apparatus has a tubular conduit with at least one seal attached to it that forms a seal between the well casing and the exterior of the conduit. The seal is held in place on the tubular conduit by two shoulders formed where the upper and lower sections of the conduit meet a middle section. The upper end of the conduit is adapted to releasably engage the lower end of a bailer. The upper end of the conduit releasably engages the middle section and can be removed to replace the seals when worn. The apparatus has a valve section designed to releasably engage the lower end of the tubular conduit or the lower end of a bailer.
