摘要

The water guard (10) has a check valve (11) arranged in flow direction behind a water inlet (6). A control unit (12) is provided for operating the check valve. A flow sensor (13) is connected to the control unit. The control unit closes the check valve when the flow data determined by the flow sensor meets a predetermined criterion. The control unit has a time switch (17), and the stop valve is closed when the flow sensor detects continuous current for more than the given length of time. Independent claims are included for the following: (1) a water dispenser for supply water (2) a method for protection from damage of a fluid leaking from a pipeline.
