ABSTRACT:
A water safety valve, system and method for detecting and shutting off water flow due to leaks or breaks in a water line in which the water flow is at a very low rate on the order of three to five fluid ounces per minute but having the capability of passing large flows of three hundred to five hundred times this amount. The system provides an automatic fluid shut off with an over-ride timer with an automatic return to normal operation when a predetermined period has expired. It further allows simple shut off and activation of the system with a single conveniently located control.
