I have the wireless remote water shut off system called FLO n STOP. It was easy to install. I just push the Off Button every time I leave the house and I never come home to a leak or flood. This makes it easy to turn your main water valve off. When I come home, I just push the On Button, and all water is restored. There will be a floor sensor which I'm told will be out this October that will sense water and send an alarm when water touches it. This will be a great add on and it also is wireless.
