ABSTRACT:
A water leak detection valve system is provided including a water inlet pipe for receiving an unlimited amount of water. Also included is a water outlet pipe for supplying various water appliances within a building with water. A water valve is connected between the water inlet pipe and the water outlet pipe. The water valve is adapted to preclude the flow of water therebetween upon being closed. Next provided is a water flow monitor device connected between the water inlet pipe and the water outlet pipe. The water flow monitor device serves to monitor the current flow rate of water through the water pipes and further begin a timer upon the beginning of water flow after each cessation of such water flow, wherein the timer continues to track time only as long as water flow continues. The water flow monitor device is further adapted to close the water valve upon certain criteria being met.
