Abstract:
1. A plumbing fixture for receiving flushable waste comprising: a receptacle for receiving the waste; a tank for storing a volume of water; an electrically operated pump having an inlet in communication with the interior of the tank and having a pump outlet coupled to the receptacle; a sensor that produces a level signal when the water in the tank reaches a given level; an input device operable by a user to produce a flush signal; and a controller connected to the sensor, the input device and the pump, wherein the controller responds to the level signal from the sensor by operating the pump to deliver water from the tank to the receptacle thereby preventing the tank from filling with an abnormally large amount of water, and responds to the flush signal by operating the pump for a predefined interval to deliver water from the tank to the receptacle, wherein the controller provides a high water level indication to a user in response to the level signal.
