A plumbing fixture for receiving flushable waste comprising:
a receptacle (12) for receiving the waste;
a tank (17) for storing a volume of water;
an electrically operated pump (22) having an inlet in communication with the interior of the tank (17) and having a pump outlet coupled to the receptacle (12);
a sensor (44) that produces a level signal when the water in the tank (17) reaches a given level;
an input device operable by a user to produce a flush signal; and
a controller (40) connected to the sensor (44), the input device and the pump (22), wherein the controller (40) responds to the level signal from the sensor (44) by operating the pump (22) to deliver water from the tank (17) to the receptacle (12) thereby preventing the tank (17) from filling with an abnormally large amount of water, and responds to the flush signal by operating the pump (22) for a predefined interval to deliver water from the tank (17) to the receptacle (12), wherein the controller (40) provides a high water level indication to a user in response to the level signal. |
