Abstract: An apparatus for removing denser materials from the bottom of an oil storage tank provides an extended bottom hose with multiple openings which lies on the bottom of the tank. The bottom hose is attached to a riser through which liquid is removed from the tank. The bottom hose and riser assembly can be partially assembled prior to lowering it into the tank, with assembly completed after the bottom hose has been lowered through an opening and is completely within the storage tank. The extended bottom hose removes denser materials from a larger area on the floor of the tank than is possible from a single opening. A sample tube is provided attached to the riser just outside the storage tank to allow sampling of the liquid being pumped from the tank. The cleanout process can be shut off when good oil begins to be pumped out of the tank.
