If water remains in the pipes for too long, it is called “standing water” or "stagnating water" and should not be drunk if you have a bad immune system. Piped water dispensers always dispense fresh drinking water, provided that the water is allowed to run for a few seconds before bottling. At unfavorable temperatures in summer, water dispensers that have not been used for a very long time can cause legionella to multiply so much that the threshold that is compatible with humans is exceeded. Diarrhea, among other things, can then be one of the unpleasant consequences. To get ahead of this, we offer automatic hygienic flushing. This automatically cleans the internal water pipe with fresh tap water every 4 hours.
