Some of the old houses easily ruptured pipes.If we can notice before it happended then I can deal with the problem. I designe a water valve installed in the pipe connections, the middle of the valve which contain a small chip with a receiver can promptly connect with application. Through the water which go through the tube, and internal spring system sends a silent sonic companion pipe back, we can tracking the outlet pipe of the seat and seepage condition.And when we repair the water pipe always need to find the exit and turn it off .So I designe a water shut-off valve can be done directly from the problem and then turn off the water tube.
