Each local line has on the input side a leakage protection fitting, which also contains a water meter, furthermore at least one tapping point and at the end a water fitting with shut-off valve to a drain. By means of a control device on the latter water valve, the shut-off valve can be opened when the volume flow is below a threshold value for a selected stagnation period.
