Toilet leak detection and overflow prevention system
First Claim
1. A combination overflow control and leak detecting system for a toilet, comprising:
- a first magnetic detector secured in a toilet tank for detecting the level of water in the toilet tank;
the first magnetic detector being adjustably mounted on a float held in the toilet tank and including means activated by rising and falling levels of water in the toilet tank;
a second magnetic detector adjustably mounted on a second float held in the toilet for detecting an overflow condition in the toilet; and
a valve means connected to the magnetic first detector and the second magnetic detector for controlling the flow of water to the toilet when actuated by either the first magnetic detector or the second magnetic detector.

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.

9. A combination overflow control and leak detecting system for a toilet tank, comprising:
-
a toilet tank having a waterline connected thereto; a microprocessor-operated, normally-open valve, including an electrical power source held in a housing, connected in the waterline to control the flow of water to the toilet tank; a first water level sensor and a second water level sensor mounted in the toilet tank; means for connecting the first water level sensor and the second water level sensor to the microprocessor, and a time-increment adjusting means cooperating with the microprocessor for controlling the flow of water into the toilet tank if either the first water level sensor or the second water level sensor detects a leakage of water and sends a signal to close the normally-open valve. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
