Claim:
A bath drain assembly for use with a bathtub having a bottom with a drain, end walls, and sidewalls, comprising: a drain closure device operatively associated with the drain to open and close the drain; an actuating member that engages the drain closure device to move the drain closure device from an open position to a closed position, said actuating member being a substantially cylindrical member having at least one magnet positioned thereon and having a conical portion with a protuberance extending therefrom; a coil positioned about the actuating member such that when exposed to a current, the actuating member moves from a first position of use, wherein a stem of the drain closure is situated on top of said protuberance and said drain closure device is in said open position, to a second position of use wherein said stem of the drain closure rests on a cylindrical portion of said actuating member after being moved along said conical portion and said drain closure is in said open position; and a sensor adapted to sense a pre-selected level of water and send a signal activating the actuating member to move the drain closure device to the open position when the water level is sensed.
