Abstract
The automatic shut off for stuck open flush valves in toilet water tanks and water saver device depicted herein consists of a simple mechanism for installation in the water tank of a conventional water flush toilet, underneath the ball float, to provide a time delay action so that the device will not operate during normal flushing operations, but will shut off water flow into the tank when an open, mal-functioning flush valve allows the tank to empty and water flow continously to waste. The system assembly consists of two cylinders, one within the other; actuated to separate by a coil spring, ball float and spring release mechanism; to force one cylinder, with toilet tank ball float adapter, upward; shutting off the water flow into the toilet tank.
