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.

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 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 plumbing component includes a valve provided within a portion of the plumbing component and configured to control the flow of water through the plumbing component. The valve includes a body and at least one waterway within the body. An electric heater extends through at least a portion of the body of the valve and is configured to heat at least a portion of the body to an elevated temperature sufficient to kill organisms within the waterway.

A flushing station for a ring-pipe or series-pipe system, comprises a cold water port for connecting a cold-water pipe, a hot water port for connecting a hot water pipe, and a waste water port, wherein the cold-water port and the hot water port are fluidicly coupled to the waste water port. The cold-water port, the hot water port and the waste water port are assigned to a bottom side of the flushing station.

A shower head having a stem; a spray head coupled to the stem; a mixing valve located within the stem or the spray head, the mixing valve having a first valve member assembly for controlling a first fluid flow to a mixing chamber and a second valve member assembly for controlling a second fluid flow to the mixing chamber. Each valve member assembly includes a spool, a first valve member on the spool that engages with a first valve seat in a closed position and a second valve member on the spool that engages with a second, separate, valve seat in the closed position. An electrically powered first motor is located within the stem or the spray head. The first motor is coupled to the first valve member assembly to control movement of the first valve member assembly to control the flow of the first fluid to the mixing chamber.

A system for maintaining conduits and pipes after their installation into a pipeline system used to transport material in a fluid or flowable form. The system includes a maintenance tool adopted for use inside the pipe, an umbilical attached to the maintenance tool for pulling the tool through the pipe; and a pluralities of bearings positioned around the umbilical in order to allow the tool to be pulled through the pipe around bends and turns in the pipe.

An apparatus and a method of extracting buried lead water supply pipe with minimal excavation and which allows removal and containment of the lead pipe. The extraction apparatus includes a frame having an upwardly extending mast, a guide pulley mounted on the frame, and a pulling apparatus mounted on the mast. A take-up spool is mounted on the mast between the guide pulley and pulling apparatus and positioned to force a pipe pulling cable into a non-linear path between the guide pulley and the pulling apparatus. Extracted pipe is pulled into the non-linear path until the pipe is fully extracted from the ground. Multiple spiral loops around the take-up spool by the pulling cable may be necessary to fully contain the extracted pipe. Following extraction, the pipe may be unspooled from the take-up spool, the pulling cable removed for re-use, and the pipe may then be sent for disposal.

A method and system for measuring, controlling, and recording flushing of a water distribution system (WDS) comprising each portion or subject WDS piping, by measuring, controlling and recording the selected flow rate ranges of water into and out of. The selected volume of water utilized into and out of the WDS piping can then be measured, controlled and recorded. The flow rate and volume of water into and out of the WDS piping can then be selected for each maintenance event protocol and used to determine the condition of the WDS.

A flushing station is provided. The flushing station includes a connection piece for a hot water pipe, a connection piece for a cold water pipe, a collecting tank with a siphon for draining the water, pipes at the connection pieces which conduct the water from the connection pieces into the collecting tank at least one sensor per pipe a control unit connected to the sensor, a valve actuatable in the pipes, wherein the control unit is coupled to the actuatable valve and the actuatable valve can be opened by the control unit for flushing the hot or cold water pipe. According to the invention, a flow restrictor and a flow straightener are integrated in each of the pipes.
