The nature of our invention is the permanent attachment of a tank which contains a pump with a discharge pipe and a floating lever switch to the bottom of a utility sink to provide for the elimination of restriction of the placement of the utility sink above the discharge waste water system which always requires gravity for the flow of the liquid in the sink. The invention allows for locating the utility sink with a washer and dryer at any level in a building eliminating the restriction of always maintaining the use of gravity for discharge of sink liquids.
