Abstract:
1. A toilet overflow prevention device for use with a toilet having a tank, a bowl, a passage connecting the tank and the bowl, and a flush valve selectively permitting water to move from the tank to the bowl, the device comprising: an overflow valve having an open position, wherein water is permitted to flow past said valve, and a closed position, wherein water is substantially prevented from flowing past said valve and into the bowl: an actuator including a water level sensor configured to sense an above-normal water level in the bowl of the toilet, said water level sensor comprising: wherein when said first inlet opening is not immersed in water, said valve is moved to a first position and said actuator permits said overflow valve assembly to move to said open position, and when said first inlet opening is immersed in water, said valve is moved to a second position and said actuator moves said overflow valve from said open position to said closed position, thereby preventing water from flowing from the tank into the bowl.
