Abstract
An accelerated drain apparatus for a walk-in bathtub, in which a pump communicates water to a valve selectively in a first position to circulate the water through nozzles into the bath water therein and in a second position to a drain, with a controller configured for moving the valve selectively between the first and second positions, and during draining, stopping the pump in response to a signal from a water level sensor and after a predetermined period of gravity draining of residual water, moving the valve to the first position for subsequent filling and use of the walk-in bathtub.
