Patent attributes
A device of the invention comprises piping for carrying liquid such as potable water within a piping network of a building, at least two control valves, a pressure transducer to measure water pressure in the piping, a flowmeter to measure water flow and a controller to control opening and closing of the control valves based on sensed pressure and measured waterflow. The controller has a processor with preprogrammed instructions for controlling conditions under which the control valves are opened and closed by command from said controller. Two programmable modes for control are provided for use in a building under construction; a rough-in operation and a normal water-on operation. Both modes have respective leak prevention logic in the controller enabling automatic operation of the control valves for effective leak prevention. The device may be employed within a communications network in which remote computers and mobile communication devices may observe and/or control operation of the device.
