A water management system effective for managing and metering water usage and detecting and reducing water leaks is described herein. The water management system can detect a leak when a volume of water flow or change in water pressure detected by a water meter of the system is uncharacteristic for a given day and time of day at the node. Upon detecting the leak, the system alerts the user, and in some situations, remotely shuts off a water supply to preemptively address a water leakage issue.

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.

A system separation device with at least one pressure-proof tank for containing a liquid that forms a predetermined liquid level in the tank, above which level there is a gas cushion. The device contains an inlet in the upper region of the tank for fluidly feeding the tank from a first fluid system, and an outlet in the lower region of the tank for forwarding the liquid to a second fluid system. To prevent the germ-infestation of the inlet, at least one germicide material is arranged in the region of a gas cushion above the liquid level.

Embodiments of the invention provide a method, system and computer program product for managing water consumption when a user engages in a specified water using activity. In an embodiment, the method comprises detecting user movement during said activity; detecting water usage during said activity; creating a pattern associating said user movements with said water usage over a specified period of time; and using said pattern to control a supply of water for the user when the user engages in the water using activity. In an embodiment, movement sensors are used to generate data representing movement of the user during the water using activity; water sensors are used to generate data representing water usage during the water using activity; and the movement data and the water data are processed to generate a data structure correlating the user movement data with the water data.

A fluid control device includes an electric motor mechanically connected to a fluid valve and a sensor coupled to a fluid pipe section. The sensor may be a temperature, pressure or flow rate sensor. A control device processor is configured to enter into a pre-occupancy mode when powered and never previously wirelessly connected to a remotely disposed fluid monitoring and control system. The pre-occupancy mode may close the fluid valve if at least one of the following occurs: exceeding a first preset threshold for a pressure decay test; exceeding a second preset threshold for a maximum flow rate; exceeding a third preset threshold for a maximum flow duration; exceeding a fourth preset threshold for a maximum flow volume; exceeding below a fifth preset threshold for a low temperature; exceeding above a sixth preset threshold for a high temperature; and/or exceeding above a seventh preset threshold for a high pressure.

A system for monitoring and controlling a flow of fluid in an environment and a method of using the system to control the flow of fluid in the environment. The system comprises a main valve positioned at an entry point of the environment. The main valve permits fluid to be discharged into the environment upon receipt of an authorized request to a controller from one or more authorizing signaling devices. The controller communicates with the authorizing devices and processes signals from the authorizing signaling device to control the flow of fluid in the environment. The system may also comprise one or more monitoring signaling devices positioned in the environment intermediate the main valve and an authorizing signaling device.

In an embodiment, a fire hydrant elbow includes a first portion joined with a second portion, the second portion having a center axis angled from a center axis of the first portion. A main valve seat faces radially inward toward the first center axis from the first annular wall, the main valve seat defining a step from a first radius to a second radius, the first radius being larger than the second radius. A guide rib is adjacent the main valve seat between the first portion and the second portion, the guide rib protruding radially inward toward the first center axis. In another embodiment, a main valve seal guide for a fire hydrant includes an annular body and a plurality of guide ribs coupled to the annular body. Each guide rib has a first surface, and each guide rib extends from the annular body to the first surface.

A state analysis device is capable of determining a state of the interior of piping with high precision, and includes: an index calculation means for deriving an index indicating the state of the piping, based on a flow speed of fluid flowing out of the piping, and a fluid pressure of the interior of the piping at two or more locations of the piping; and a determination means for determining the state of the piping, based on the index.

A drinking water supply system includes a drinking water line system, a plurality of drinking water withdrawal points connected to the drinking water line system, at least one sensor which is designed to determine measuring values, and a central control device which is designed to receive and evaluate the measuring values determined by the at least one sensor. The system also includes a presence detector designed to determine information about the presence of a person, or an acoustic sensor designed to measure measuring values for the volume. The central control device is designed to control the drinking water supply system as a function of the information about the presence of a person or as a function of the measured values for the volume. A method for controlling such a drinking water supply system and a computer program that causes the method to be carried out are also provided.

A water control system which encompasses a leak sensor and a water control unit adapted for installation on a water supply line, both capable of wireless data communication with a gateway acting as an interface between the leak sensor and water control unit and a cloud server or a remote user application.
