There was a time when lavatory sink water on most USA carriers was labeled as potable while that on most foreign carriers was labeled as nonpotable. I also remember seeing some little spigots to fill water glasses on walls near lavatories and galleys.

To clarify, it was stated by the CSD that the problem “affected use of the toilets” so having not checked directly myself, it may have been the case that they still flushed but there was no water from the taps. I made an assumption based on the way it was phrased in the announcement

Waste water that is used during toilet flushing is held in black water tanks, and empties by the "honey wagon" on arrival at destination. It is NOT expelled from the aircraft like the old fashioned trains.
Water from hand washing in sinks and galley sinks is expelled through super heated drain lines into the outside air.

I sure as hell nobody does this in the air. No way would super heated even account for outside air temps -90 degrees and there would be lots of dents and holes in aft surfaces from ice blivets building up behind drains

While I haven’t operated the A380, this isn’t the case on the 787. The potable water system provides water to the toilets and sinks as well as all galley systems. I’d be surprised if the A380 is different to be honest, but I’m happy to be informed otherwise. Chemical toilets haven’t been used on commercial jet aircraft since the likes of the 737 Classics and 757s.

Just a regional pilot but ours drains in flight. Goes out the bottom. Even if it does instantly freeze nothing adverse could happen cause it wont adhere to the fuselodge and build up. I imagine the 380 is similar.

To stop it freezing in the drain lines. Outside air temperature is very cold (-50°C ish at cruise, of course this varies). So the lines are heated so no freezing occurs until after exited the aircraft, otherwise it would freeze in the tubes and cause a blockage.

Airbus also has poor air circulation, as it always ended up that one of the cabins in Y on the A330/A340 would be freezing cold, and other would be very warm.

Indeed it was and was in response to someone asking why the route matters - because sometimes it does.
And surely it's posible for an A380 to be diverted to an airport where it's not possible to take on additional potable water.
Plus the discussion had moved on from specifics to the A380 to water in general
