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.

What is claimed is: 1. A system for the remote control of water flow through a water-supply line, comprising, a transmitter for sending coded stop and start radio frequency (RDF) signals, and a water shut-off unit, said water shut-off unit comprising: a housing that is substantially sealed to preve
What is claimed is: 1. A system for the remote control of water flow through a water-supply line, comprising, a transmitter for sending coded stop and start radio frequency (RDF) signals, and a water shut-off unit, said water shut-off unit comprising: a housing that is substantially sealed to prevent the incursion of water or moisture, a motorized ball valve located within said housing and connected to said water supply line such that the water flows through said housing and said motorized ball valve, a controller located within said housing and capable of receiving the coded RF signals from said transmitter, said controller having means for deciphering said coded RF signals and means for sending an electrical signal corresponding to said decoded signal to said motorized ball valve; a power supply source for providing electrical power to said controller and said motorized ball valve, wherein, when said motorized ball valve is in an "open" position and said transmitter transmits a coded "stop" signal to said controller, said controller actuates said motorized ball valve to rotate 90째 to a "closed" position and thus stop the flow of water and, conversely, when said motorized ball valve is in a "closed" position and said transmitter transmits a coded "on" signal to said controller, said controller actuates said motorized ball valve to rotate 90째 to an "open" position and thus start the flow of water. 2. The system according to claim 1 wherein the transmitter sends the coded RF signals through a wire to said controller. 3. The system according to claim 1 wherein said water shut-off unit further comprises a rechargeable power supply and means of recharging said rechargeable power supply. 4. The system according to claim 3 wherein said means of recharging said rechargeable power supply comprises a solar powered battery charger. 5. The system according to claim 3 wherein said means of recharging said rechargeable power supply comprises a direct current receptacle for receiving battery charging current form an external source. 6. The system according to claim 1 wherein said water shut-off unit further comprises means for attaching an external device for evacuation of the water line or injecting a fluid medium into the water line. 7. The system according to claim 6 wherein said means for attaching an external device comprises an evacuation/injection port comprising a coupling device. 8. The system according to claim 1 wherein the transmitter sends the coded RF signals wirelessly to said controller. 9. The system according to claim 1 wherein said water shut-off unit further comprises an antenna connected with said controller for receiving said coded RF signals from said transmitter. 10. The system according to claim 1 wherein said controller further comprises at least one power relay for relaying direct current to said motorized ball valve. 11. The system according to claim 1 wherein said controller comprises a printed circuit board. 12. The system according to claim 11 wherein said controller is configured to operate said motorized ball in only a clockwise or a counterclockwise direction. 13. A wireless system for the remote control of water flow through a water-supply line, comprising, at least one wireless transmitter for sending coded stop and start radio frequency (RDF) signals, a water shut-off unit, said water shut-off unit comprising: a housing that is substantially sealed to prevent the incursion of water or moisture, a motorized ball valve located within said housing and connected to said water supply line such that the water flows through said housing and said motorized ball valve, a controller located within said housing and capable of receiving the coded RF signals from said transmitter, said controller having means for deciphering said coded RF signals and means for sending an electrical signal corresponding to said decoded signal to said motorized ball valve; a power supply source for providing electrical power to said controller and said motorized ball valve, wherein, said at least one wireless transmitter is coded to match said controller by way of an externally mounted antenna capable of receiving said coded RF signals, and wherein when said motorized ball valve is in an "open" position and said transmitter transmits a coded "stop" signal to said controller, said controller actuates said motorized ball valve to rotate 90째 to a "closed" position and thus stop the flow of water and, conversely, when said motorized ball valve is in a "closed" position and said transmitter transmits a coded "on" signal to said controller, said controller actuates said motorized ball valve to rotate 90째 to an "open" position and thus start the flow of water.
