The flushing process is intended to remove contaminants, for example the remnants of solder or sealant from the drinking water pipes. The individual pipe circuits must be flushed from bottom to top. It is possible to observe the flushing action by means of transparent pipe sections. Flushing is performed via two lines that are connected to a cold water supply. Contaminants are introduced into the pipe system through openings with shut-off valves.

  Original plumbing components are used in the unit.
