Claim 8:
9. A method for leak detection of water within piping and to control water flowing through the piping to prevent water damage in the event of a detected leak, said method comprising:
providing piping for carrying water;
providing a leak detection and control device comprising: a first control valve mounted in said piping for receiving water from a water source;
a second control valve mounted in said piping located downstream from said first control valve and receiving water from said first control valve;
a pressure transducer communicating with said piping to measure water pressure therein; a flowmeter communicating with said piping to measure water flow therein;
a controller to control opening and closing of said first and second control valves, said controller having a processor, a data storage element, and preprogrammed processor instructions for controlling conditions under which said first and second control valves are opened and closed by command from said controller;
monitoring a status of water in the piping wherein said first and second control valves are opened and closed based upon measured changes of pressure and water flow within said piping;
executing processor instructions of said controller including
a first phase construction mode of operation in which a measured pressure drop in the piping indicates a leak and said second control valve is operated to prevent flow into the piping and water in the piping is directed to a drain;
executing processor instructions of said controller including a second phase construction mode of operation in which the measured pressure drop or a measured amount of flow in the piping indicates the leak and said second control valve is operated to prevent flow into the piping and water in the piping is directed to the drain; and
providing a first user interface showing data associated with said first and second phase construction modes of operation.
