A drain emanating from a substantially circular opening in a basin, sink or tub is provided with a substantially cylindrical member releasably connected to the basin, sink or tub. The substantially cylindrical member is provided with a fluid inlet for receiving a pressurized fluid and an expandable bladder located within the substantially cylindrical member in fluid communication with the fluid inlet, wherein the bladder is sized and positioned such that when expanded, it blocks the drain to the passage of water. A mechanical pump is provided having a pump chamber and a stem emanating from it such that when the stem is moved, fluid pressure is applied to a hydraulic line connected to the fluid inlet for selectively expanding the bladder.
