Abstract: The invention is directed to a toilet overflow prevention device. The device is a toilet tank shutoff system, composed of a sensor for use in the toilet bowl or tank, an electro-mechanical actuator, and an electronic communication link. The electromechanical actuator is configured to raise the control rod, which controls the filler valve of the toilet. A latch mechanism would retain the control rod, once it is raised. The system would raise the control rod upon receiving a signal from the sensor that the toilet is at risk of overflowing; the control rod would be retained in the raised position by the latch mechanism without requiring electric current, until released manually by the user. The sensor in the toilet bowl would preferably be in electronic communication with the electro-mechanical actuator in the toilet tank by a wire covered in a durable material, or by a short range, wireless communication protocol.
