<p>A microprocessor-operated flow control device for a toilet to prevent flooding upon obstructing of a waste outlet of a toilet bowl also includes a leak detector for measuring any water leakage from a toilet tank. The device includes a water level sensor assembly mounted on a clip held over a rim of the toilet bowl so as to hold the water level sensor assembly in a predetermined position within the toilet bowl, and a leak detecting element held in the interior of the toilet tank. If water bridges contacts on the water level sensor assembly, an electrical circuit or an RF connection is completed to the microprocessor in a housing, and an electric motor is actuated to drive a gear train to close a normally opened valve and shut off water to the water tank of the toilet. If a water leak is detected, an electrical or an RF signal is sent to the microprocessor to shut off water flow to the water tank. The present invention is an easily-added-on, simplified device for use with a toilet to prevent flooding and wasting water through leakage.</p> |
