In response to the current question of whether viruses are transmitted through tap water, first two good pieces of news:

1) Viruses and bacteria are completely retained by water filter systems from truu GmbH, so a "firewall for the kitchen" is in any case possible.
2) The Federal Environment Agency has published a statement on the current situation in which it states: "Water does not represent a relevant transmission route for SarsCov 2 viruses. These enveloped viruses show low persistence in water compared to enteroviruses and are easier to inactivate than noro- or adenoviruses."

The statement from the Federal Environment Agency is consistent with a study that was already published in 2008 in the scientific magazine "Springer". It states: "Coronaviruses die off very quickly in wastewater, with a 99.9% reduction in 2-3 days."

The situation is quite different in the case of noro- or adenoviruses. In 2005, the University of Helsinki found in studies that during the period from 1998-2003 in Finland there were dozens of cases of water-related norovirus outbreaks. (Symptoms are usually diarrheal diseases but also inflammations).
