A supply assembly for use with a hydrant comprising a first supply valve adapted for coupling to a first supply line of the hydrant and a second supply valve adapted for coupling to a second supply line of the hydrant. A housing contains a first drain valve and a second drain valve. The first supply valve is coupled to the first drain valve for permitting water to be drained from the first supply line when a first outlet of the hydrant is off, and the second supply valve is coupled to the second drain valve for permitting water to be drained from the second supply line when a second outlet of the hydrant is off. The first supply valve is above the second supply valve to permit radially compact nesting of the first supply valve and the second supply valve. Related assemblies, valves and methods are provided.

A geothermal heat containment barrier operable to be manipulated through an opening of a vault by at least partially folding the geothermal heat containment barrier, and positioned substantially horizontally against walls of the vault to reduce heat transfer through the barrier is provided. The barrier includes a central insulating core, a flexible outer frame, and an outer sealing trim. The central insulating core includes top and bottom outer surfaces and a perimeter edge. The central insulating core includes and/or contains an insulating material. The flexible outer frame has a shape memory and includes at least one flexible component having ends together such that the flexible outer frame is continuous and closed. The outer sealing trim is attached to the top and bottom outer surfaces and wraps around the perimeter edge of the central insulating core. The outer sealing trim is operable to press against the wall of the vault.

A method of operating an appliance includes receiving an initiation trigger to perform a flush operation, supplying water to a container of the appliance, draining the supplied water from the container, measuring a temperature of the supplied water to the container, determining that the temperature of the supplied water is above a predetermined temperature threshold, and halting the supply of water to the container via the water supply.

A fluid handling assembly comprising a cavity in which water may become trapped due to use of the assembly, and a membrane disposed in the cavity. The membrane divides the cavity into a first sub-cavity on a first side of the membrane that is configured to collect any water trapped in the cavity and a second sub-cavity on a second, opposite side of the membrane. The membrane is configured to change shape such that the first sub-cavity increases in volume and the second sub-cavity decreases in volume in response to being subjected to water freezing conditions. The increase in volume accommodates an increase in volume of any water that may be trapped in the first sub-cavity when it freezes to ice.

A removable liquid transport assembly configured to be readily installed in and removed from a liquid dispenser to permit the liquid dispenser to be readily sanitized. The removable liquid transport assembly preferably includes a liquid manifold, a valve assembly and a pump head. The removable liquid transport assembly is configured such that liquid can flow in a first direction through the removable liquid transport assembly to permit a liquid to be dispensed from a liquid dispenser and liquid can flow in a second direction back to a liquid storage container to prevent damage to one or more components of the liquid dispenser.

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.
