The present invention relates to a flushing device that can be connected to a potable water system for flushing at least one water line (4), the flushing device comprising a flushing valve (8), a control line (24) that is connected to the flushing valve (8) in a controlling manner and a control device (22) that controls a position of the flushing valve (8) via the control line (24) in a time-dependent manner and/or in a manner depending on a water temperature and/or in a manner depending on a water consumption. In order to comply with the hygiene requirements for a potable water system and to enable efficient flushing, the flushing device according to the present invention is adapted to control the flushing process in a manner depending on the water pressure.

A mixing valve includes a mixing chamber, a first flow control valve having a first flow control opening, and a second flow control valve having a second flow control opening. The first and second flow control openings each have a diameter of approximately six millimeters and the mixing valve has a flow coefficient of approximately 2.5 when both flow control valves are in a mid-open position.

Example aspects of a remote-operated flushing system and a method of operating a flushing system are disclosed. The remote-operated flushing system can comprise a fluid routing assembly comprising a valve, the valve configurable in an open configuration, wherein fluid is permitted to flow through the fluid routing assembly, and a closed configuration, wherein the fluid is prohibited from flowing through the fluid routing assembly; a control device configured to actuate the valve between the open configuration and closed configuration; a remote operation device wirelessly connected to the control device and configured to remotely operate the control device to control the actuation of the valve between the open configuration and closed configuration; and a sensor configured to detect a fluid property of the fluid within the fluid routing assembly, wherein the control device is configured to wirelessly send a signal representative of the fluid property detected by the sensor.

The present invention relates to a fluid handing device that can be attached to a water main or other fluid supply infrastructure. The device has a branched, hollow body containing a fluid passageway, that has a first end, a second end, a right arm member, a left arm member and a top member. The body also includes a male threaded nipple connected to a ball valve, and the nipple has a shutoff valve that allows a user to cut off flow from the nipple to the device. The second end of the body further has two arm members with hose adapters that allow hoses or other fluid conduits to be attached to the device, to allow water or other fluid to flow through the device and into a water main or fluid infrastructure for flushing, cleaning or treatment.

A mixing valve that includes a housing having a first outlet, a second outlet, and a mixing chamber; a first flow control valve for controlling flow through the first outlet to the mixing chamber; and a second flow control valve for controlling flow through the second outlet to the mixing chamber; wherein the housing has a length dimension, a width dimension, and a thickness dimension, and the largest of these dimensions is no more than approximately 65 millimeters.

The present invention refers to a drinking and service water system with a connection (2) to the public water supply network, at least one supply line (4, 6) leading to at least one consumer (8), a flushing valve (10) downstream of the consumer (8) in the flow direction for draining water from the drinking and service water system, a control unit (12) connected to the flushing valve (10) in terms of control, and a first temperature sensor (18) upstream of the consumer (8) in the flow direction, the control unit (12) comprising a flushing module which determines flushing processes to the control unit (12) at specific times and/or at specific time intervals. This invention is intended to provide a drinking and service water system which, with an efficient flushing device, fulfills the hygienic requirements placed on a drinking water system. To solve the problem, a second temperature sensor (20) is arranged between the consumer (8) and the flushing valve (10) and the control unit (12) is arranged to decide whether the predetermined flushing operation is to be suspended or postponed on the basis of a temperature difference between a measured value of the first temperature sensor (18) and a measured value of the second temperature sensor (20). In a secondary aspect, the present invention provides a method for flushing such a system.

A pipe rehabilitation system and/or robot can be used inside a pipe to measure characteristics of branch conduits, install plugs into branch conduits before the pipe is lined with a liner, remove portions of plugs and liners after lining to restore fluid communication between the pipe and branch conduits, and/or install fittings into the branch conduits to connect the liner to the branch conduits. A probe can measure characteristics of a branch conduit. A tool can install plugs and/or fittings into the branch conduits. A linkage can connect a tool to a robotic tractor so that the connected elements can navigate through a main pipe. A visualization system can aid in aligning a robot with a branch conduit. Height-adjustable braces can support robotic tools in a pipe. A plug can include integrated locating features and/or movable parts that enable expanding the plug to seal with the branch conduit.

A fluid flushing system includes a sampling port comprising a sampling conduit configured to dispense a sample of a fluid in the fluid routing assembly; a valve configurable in an open valve configuration, wherein the fluid is permitted to flow through the fluid flushing system, and a closed valve configuration, wherein the fluid is prohibited from flowing through the fluid flushing system; and a backflow preventer disposed between the sampling port and the valve, the backflow preventer configured to allow the fluid to flow in a first direction through the fluid flushing system towards the valve and to prevent the fluid from flowing in an opposite second direction through the fluid flushing system towards the sampling port.
