The system has a transfer point of a public drinking water supply net, and a floor line and/or a riser line (2) and a set of closed circular pipes (10), where the pipes are guided to a tapping point (12) and arranged in series in an extension direction of the line. The circular pipes exit in the riser line and discharge in the line in the flow direction of the line. A controllable valve produces a rinsing current in the line in an opened condition, such that water in the line is exchanged and discharged into a sewage disposal network. An independent claim is also included for a method for operating a drinking or an industrial water system. |
