ABSTRACT:
A stopper assembly for a drain pipe includes a closure member having a stopper at one end and a cylindrical portion configured to fit into the drain pipe. An actuator disposed outside the drain pipe is magnetically coupled to the closure member and may be manipulated to raise and lower the closure member so as to open and close the drain outlet. The magnetic coupling avoids the need for any levers or other mechanical elements to pass through the wall of the drain pipe.
