Abstract: A remote controlled system for shutting off a water supply and testing for leaks, having within a sealed housing a motorized ball valve device with an electronic controller, antenna, power supply, battery-charging device and an evacuation/injection port. The controller receives signals through the antenna from a wireless remote control device, when either of two buttons on the remote control device is pressed the controller receives the wireless RF signal and activates the motorized ball valve device which either stops or starts the water flow through the water line. The battery-charging device is connected to a source of alternating current by a power plug. If the system is installed below-ground an external battery charging device that operates by solar means is connected using matching quick connectors and positioned on the outside of the sealed housing.
