Abstract: A system for preventing freeze-induced rupture of a supply pipe is provided, comprising remote and internal temperature sensors for determining first and second temperature data, a flow control device for attachment to the supply pipe. The flow control device comprises an upstream inlet configured to be connected to the supply pipe, a downstream outlet configured to be connected to a drainage pipe, at least one valve disposed between the inlet and the outlet and configured to selectively move between a closed position in which liquid is blocked from flowing therethrough and an open position in which flow of liquid is permitted therethrough, and at least one flow control component configured to limit the flow rate of liquid therethrough. The system further comprises a controller configured to control operation of the at least one valve based at least on one of the first temperature data or the second temperature data.

Abstract: Disclosed herein are flow control devices including at least one remote temperature sensor configured to determine first temperature data associated with air outside of a dwelling; a valve configured to control a first flow rate of the liquid flowing from an inlet of the supply pipe along a controlled liquid flow path by moving a valve position from a closed position to an open position; a flow control component in fluid communication with the valve, and configured to control a second flow rate of the liquid flowing from the valve; at least one internal temperature sensor configured to determine second temperature data associated with air inside the dwelling; a controller communicatively connected to the temperature sensors and configured to control operation of the valve based at least on at least one of the first temperature data and the second temperature data; and a housing configured to contain the flow control device components and further configured to releasably attach to a spigot or spout of a supply
