ABSTRACT:
A system connectable to a water line for controlling the flow of water includes an underground housing, a shut-off mechanism disposed within the housing and connected to the water lines, and a controlling mechanism including a wand for sending a signal to the shut-off mechanism and thereby open and close the system. The shut-off mechanism includes a motor, an actuator interface, and a drive shaft operably connected to each other wherein the drive shaft rotates based upon the signal from the wand so that water flow can be adjusted as desired by an operator. The controlling mechanism includes an antenna and transceiver for communicating with the wand. The actuator interface is coupled to the antenna for processing and communicating a signal received from the wand and transmitting same to the motor and drive shaft.
