    (it’s dual because law forbids connecting undrinkable water to drinkable water systems)

    Are you implying that hot water is undrinkable? Sorry, I don’t understand but it sounds really interesting.

      In short, you shouldn’t drink hot water from open systems (popular in UK back in the day) or from boiler that doesn’t have a periodical disinfection program (hetaing to 90C once a week)

      Even in NA you shouldn’t drink hot tap water. The tanks get covered in scale, there’s always the risk of legionaries.

      Where are you that they suggest drinking from the hot tap is okay? It’s not inherently gonna kill you, but hot water tanks aren’t pristine either… you can sure open your mouth and swallow a little while showering, but don’t be making your tea or using it to boil water faster for food.

        Thanks for the explanation. I don’t drink hot water (I filter drinking water in the fridge) I just didn’t realize hot water was undrinkable and that there were laws against hooking it up to cold water.

          Even if you drain them yearly and “descale” them, it’s never gonna be pretty in there.

          You can use a backflow preventer so it doesn’t go back into the city supply which lets you do what you please inside. Even irrigation systems need them, if a main break or a hydrant gets used to fight a fire. There’s the potential for there to be a drop in pressure and it pull stuff out of the ground (or hot water tank) back into the municipal supply.

            Woah, that’s intense, at first I thought that was some kind of eldritch creature. The house I’m in just got a new hot water tank, I’ll ask what they’re doing about maintaining it.
