nigelinuxPeople around the world, do you drink tap water without boiling?
German here. Yes, constantly. The only reason to not do it would be taste (personal preference) or sometimes due to pollutants entering the system, which is explicitly communicated by the city.

Which IMO depends on the hardness. I’m from Flensburg originally, the water there is at around 1° dH (~18 ppm). Amazing water, I’d always drink it straight from the tap. It tastes as if it were sweetened.
Now I’m in Lübeck, 17° dH (~303 ppm; measured in a lab) and I can’t drink it unfiltered. I usually switch the filter after slightly over a week, measured (with indicator liquid, so not super exact) when it tastes noticeably bad at 9° dH (~160 ppm).
Yes, mineral content is usually the biggest factor for taste. But it is still perfectly safe to drink straight from the tap.
Safe, physically. Not safe for me mentally :D
