Abstract:
A device for use in moving a fluid into or out of a subsurface which comprises:(a) an outer tube having an open first end and a closed second end with a center bore extending therebetween defining a longitudinal axis of the device and having at least one opening adjacent the second end; and (b) an inner rod having a first end and a second end with an outer surface having no openings with a handle mounted adjacent the first end and configured to be telescopingly inserted into the center bore of the outer tube, wherein in use, the inner rod is inserted into the center bore of the outer tube such that the inner rod closes the opening at the second end of the outer tube and the device is inserted into the subsurface with the second end of the outer tube entering the subsurface first, wherein when the device is at a desired depth in the subsurface, the inner rod is completely removed from the outer tube which opens the opening which allows fluid to be inserted or removed from the subsurface through the opening.
