    Abstract: A standing valve retrieval tool for coupling to a standing valve to allow removal of the standing valve with a tap type puller or a fishing tool. The tool comprises a coupler having a first end and a second end, the first end removably connected to a standing valve within a downhole pump barrel and the second end oriented towards a movable downhole assembly also located within the downhole pump barrel above the standing valve. The coupler has a threaded opening extending within the second end for optionally receiving a tap type puller connector to remove the standing valve and a laterally projecting collar located along the second end for optionally receiving a fishing tool connector to remove the standing valve. The coupler also includes drainage openings extending through the second end for draining debris within the fluid to prevent the threaded opening from becoming plugged.
