- the liquid path comprises one or more ring lines or
- Fluid path along the lines on one or more consumers such as taps or fittings for discharges.
- an automatic rinsing of the liquid path can be effected. Opening the purge valve provides a fluid path between the
- Liquid line and the discharge line forth whereby the liquid from the liquid path can be at least partially derived or renewed when the liquid path is connected to a liquid source.

- Control unit to be controlled, in particular time-dependent, temperature-dependent and / or dependent on the flow through the liquid path.
- Flow through the liquid path defines the number of valves to be opened in one flush in the multiple valve.
- Fluid path through the purge valve in the discharge line can thus be regulated.
- the number of valves to be opened is adapted to the volume to be purged and / or to the purging duration.
- Rinsing process automatically ends in a backwater.
- Backflow can be detected by a backflow sensor and cause automatic closure of the purge valve to prevent ingress of liquid from the discharge path into the fluid path. Especially in drinking water pipes thus contamination of the fresh drinking water is prevented by backflowing wastewater.
