The underwater drainage system is convertible from a two bottle system including a collection chamber and underwater seal chamber to a three bottle system including a suction control chamber. A rubber diaphragm is provided in the container for the collection chamber and underwater seal and a needle having a large bore is provided in the suction control chamber. Trackways on the suction control chamber and collection chamber interfit so that the suction control chamber can be slid into position. The needle penetrates the diaphragm to place the suction control chamber in fluid communication with the underwater seal chamber and collection chamber.
