Thanks. This made me checking the situation in Germany. Apperently the washing machine needs a backflow protection by law. Not sure mine has one as it's just a simple looking double faucet (washing machine + sink connection). Maybe that's going to the long list of "deadly" oversights by my landlord XD Either way, I read modern washing machines prevent this also by their own valve systems. Guess that's the fancy thingy at the end of the water connection. Hope that stops whatever is making notable hydrogen sulfide in the freshwater inflow from spreading into my drinking water... What do they even eat?? For real washing machines and fridges are just increasingly disgusting if you start asking questions... Really glad for my immune system.

The flowback protection is usually directly attached to the water inlet of the washing machine. It's not an optional thing that a landlord can skimp on, you'd have to replace the inlet entirely to get rid of it.

  Thanks. You mean e.g. this techy thing at the end of the inlet tube right? It's electrical and only opens when the machine needs water, correct? I think I read a warning about electrical hazards for this plastic tube. On the downside, this valve probably doesn't allow flushing the inlet with some hypochlorite solution easily... Well knowing the drinking water is safe helps. Hydrogen sulfide is detectable in such low quantities, I am probably stressing over very little contamination anyway. I wonder if you could reconstruct the whole of "western" civilization just from norms and regulations :)
