Patent ID: 8439062

Claim:
A system for controlling access of water to a plumbing system in a house, building or boat comprising: an actuator and valve combination characterized in that operation of the valve controls water flow therethrough from a source of water into said plumbing system, and the actuator controls operation of said valve, said actuator having functionally associated therewith means for receiving electromagnetic signals; at least one water sensing means distally located from said actuator and valve combination, comprising a communication apparatus for transmitting an electromagnetic signal to the actuator of the actuator and valve combination when said at least one distally located water sensing means sense the presence of water at its location; such that in use the actuator and valve is located between the source of water and the plumbing system, and the at least one distally located water sensing means is positioned at a location in said house, building or boat at which it is desired to prevent being subjected to the presence of unintended and undesired water, such that if water is sensed by said at least one distally located water sensing means, an electromagnetic signal is caused to be sent by the at least one water sensing means distally located from said actuator and valve combination means, and received by the apparatus for receiving an electromagnetic signal functionally associated with said actuator to the end that the valve operates and prevents the flow of water therethrough; said system further comprising a water flow sensor to sense water flow through said valve, and wherein said water flow sensor provides a signal to said actuator and valve operation when said flow rate is above a designated level, which signal blocks valve operation, but allows operation of said valve when said flow rate decreases below said designated rate.
