ABSTRACT:
Water leak detecting or overflow devices for a toilet may be inserted into or formed integrally with the toilet. The devices include at least one water leak sensor assembly mounted in a position in a toilet tank so as to detect the rise and fall of the water level in the toilet tank and an overflow detector in a toilet bowl. If the water level rises and falls a predetermined number of times, or if water continues to flow to the toilet longer than a measured increment of time, a microprocessor operates a normally-open valve and shuts off flow of water to the toilet tank. The devices also include a second sensor, whereby if a flapper remains open or water reaches a level where it might overflow the bowl or tank and stays there for a predetermined period of time, the microprocessor will also shut off flow to the toilet.
