Flood mitigation and pipe freeze prevention systems for use in a structure

A system for controlling water delivery in to and out from a structure, the system comprising:

• a plurality of sensors disposed within the structure for determining one or both of a water leak from a water delivery system within the structure and a temperature;
• a transmitter associated with each one of the plurality of sensors for transmitting a signal to a controller, the signal indicating a water leak from the water delivery system or a temperature below a predetermined value;
• a shutdown valve for controlling the flow of water into the structure;
• a pipe freeze mitigation valve for controlling the flow of water out from the structure;
• a plurality of valves at different locations within the structure for directing the flow of water within the structure;
• the controller for receiving the signal and responsive thereto for closing the shutdown valve to prevent water from entering the structure, or for opening the pipe freeze mitigation valve to drain water from the structure, or for closing one or more of the plurality of valves to control water delivery to different locations within the structure;
• a shutdown override valve oriented in parallel fluid flow with the shutdown valve and controllable to an open state for overriding a dosed state of the shutdown valve;
• a pipe freeze mitigation override valve oriented in serial fluid flow with the pipe freeze mitigation valve and controllable to a dosed state for overriding an o en state of the pipe freeze mitigation valve;
• and
• responsive to a loss of power to the structure, the shutdown valve is closed to stop the flow of water into the structure and the pipe freeze mitigation valve is opened to drain water from the structure.
