Oohh, I had this happen once in a building I lived in! Some guy hung his jacket on one of these on the 20th floor and it basically flooded all apartments on that side of the building, 4 per floor, plus the walkways too. When inenterrd the building it was raining inside the lobby. All inner drywalls were, well, not dry anymore, and had to be replaced, all carpets everywhere, all apartments had heavy water damage, people lost half their electronics in the soaking and the rotten egg smelling water basically ruined everything for basically 80 apartments.
I dont know and can't imagine what happened to the guy, would insurance cover THAT? And that much?
It was a shitshow
