Abstract
The present invention provides a drain system for a walk-in bathtub. The drain system includes a conventional drain opening in the bottom of the walk-in bathtub and a second drain opening in the side of the foot well of the bathtub. A motorized pump pumps water out of the bathtub through the second drain opening in the foot well. A first drain line provides water outflow from the conventional drain opening to a primary drain pipe. A second drain line provides outflow from the motorized pump to the primary drain pipe, and a third drain line joins the primary drain pipe from an overflow opening near the top of the bathtub. A low water sensor is coupled to the second drain line and motorized pump and deactivates the pump when the water level in the bathtub is equal to or lower than the second drain opening.
