A friend who lives in military housing with a sprinkler is kind of afraid of it. If you accidentally hit one of the sprinklers, with a ball, or something long that brushes the ceiling as you’re moving it, you just destroyed everything in your house.

With that logic we would all be using out houses instead of toilets.

All that’s holding back the water is a glass vial that melts at a certain temperature. A normal hit may bounce off but the right shock might be enough.

The best I could find was this. True, a forklift isn’t a ball, but the concept is the same.

There’s lots of stuff online warning that while very rare, the scenario could happen.

I’m remodeling my bathroom and we’re bringing in lumber for framing, drywall and other big stuff. One could easily brush the ceiling if not paying attention.
