1. A leak detection and prevention system comprising:

  • a gear motor linkage assembly comprising;

    a motor and gear box;

    a motor controller/driver module that controls operation of the motor,a push lever attached to a shaft of the motor, the push lever in a home position, wherein when a signal indicating that a leak has been detected is received by the motor controller/driver module the motor controller/driver module controls the motor to rotate the push lever so that the push level non-captively engages a handle of a valve and pushes the handle to a closed position, then the motor controller/driver module controls the motor to rotate the push lever to the home position; and

    at least one leak detection sensor comprising a detection circuit that measures the resistance between the at least two detection probes and when the resistance between the at least two detection probes is below a predetermined value a switch activates a transmitter that transmits the signal indicating the presence of a leak.
