摘要
A device for facilitating removal of a drop tube from an underground liquid storage tank, comprises a plate configured to fit within a spill restrictor fitted to the underground liquid storage tank. The plate may comprise a first main surface; a second main surface that is separated from the first main surface by a thickness of the plate, the second main surface being configured to rest on a bottom surface of the spill restrictor; a first truncated portion configured to clear any structure projecting from the bottom surface of the spill restrictor when the device rests on the bottom surface; a centrally-disposed opening configured to conform to and fit over a collar that is configured to attach to a riser pipe that rises from the underground liquid storage tank and to the drop tube; and at least one peripherally-disposed through hole traversing the thickness of the plate, the at least one peripherally-disposed through hole being configured to enable a elongate bar to be inserted therethrough and make contact with the bottom of the spill restrictor.
