I’m aware of the NCIS scenes, what else you guys got?

    This happens with fire sprinklers a lot, one sprinkler goes off, and triggers the rest of the floor, or sometimes even building.

    That’s not how it works. Each sprinkler has it’s own trigger mechanism, the glass bulb, and cannot trigger another sprinkler.

    There are systems where this happens, but the sprinkler heads look very different, and you won’t find them in an office building.

        Yes. A combination of rust, thread cutting oil, and water that has been in the pipes often since the system was filled. It smells, it will stain anything it touches, and it’s a smell that’s difficult to remove.

            That’s to test the incoming main, the actual grid on the floor doesn’t get flushed. There’s a lot of dead end pipes that can’t be flushed.

            Dry pipe systems are a thing. But not very common from my limited understanding.

          Once I turned a suspicious faucet I shouldn’t have and got a blast of this in the face.

      Also I’ve heard that the water that first comes out of those sprinklers is RANK from having sat in the pipes for years

      Theoretically the water hammer effect might be able to break that glass, but I think it’s unlikely.

      There are sprinklers where this happens and the sprinklers look exactly the same. There’s a pressure switch on the sprinkler line that activates a deluge pump. This pump has enough pressure and flow capacity to break open the glass ampules of the remaining sprinklers in the circuit.
