Abstract
An apparatus and method for an improved flushing system for flushing a water closet from a pressurized water line includes sensor which senses an arrival and a departure of a person within a zone proximate the water closet. A controller is connected to the sensor for determining the existence of a low water volume flush condition and the existence of a high water volume flush condition. The low water volume flush condition exists when the sensor senses an elapsed time between the arrival and the departure of less than a preselected time interval. The high water volume flush condition exists when the sensor senses an elapsed time greater than the preselected time interval.
