One or more microprocessor-operated flow control devices are connected to one or more waterlines to shut off flow of water if a leak detector measures any water leakage. The one or more flow control devices are operated to shut off water flow upon the water leak detector sensing leakage and sending an electrical or an RF signal to microprocessors in housings. An electric motor is actuated in each housing to drive a gear train to close a normally-open valve and shut off water flow through the one or more waterlines. The present invention is an easily-added-on, simplified device for use with any waterline to prevent damage and the wasting of water through leakage.
