Abstract
The automatic toilet bowl overflow prevention apparatus comprises of a water level sensor attaches to the rim of the toilet bowl, a hollow flexible tube connecting the water level sensor to an air vented toilet tank flapper. When the water level sensor trips, it opens an air valve and allows air to vent out from the air vented toilet tank flapper. Venting the air out of the air vented toilet tank flapper will close the toilet tank flush valve. Thus shutting off water to the toilet bowl and prevents it from overflowing. This apparatus uses an air vented toilet tank flapper for demonstration. An air vented toilet tank ball will work too. This invention is totally automatic and does not require any electrical power to operate.
