ABSTRACT:
A drain basin has a basin with walls and a cavity therein. The basin can have one or more sleeves coupled thereto. The sleeves are in communication with the cavity. The sleeves form pipe couplings to the basin. Each sleeve has a free end and a fixed end. The fixed end is coupled to the basin. The sleeve has an inside diameter that decreases toward the fixed end, which inside diameter is structured and arranged to receive the outside diameter of a small pipe. The sleeve also has an outside diameter that increases toward the fixed end, which outside diameter is structured and arranged to receive the inside diameter of a larger pipe. In addition, catches are provided to couple a corrugated pipe to the sleeve. The catches comprise fingers that flex or projections on ribs. Thus, the drain basin allows several diameters of several different pipes to be coupled to the drain basin.
