minus-squareIlovethebomb@lemm.eelinkfedilinkarrow-up0·20 days agoThis 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.

minus-squarelemonmelon@lemmy.worldlinkfedilinkarrow-up0·19 days agoI don’t think water hammer would apply because there’s no abrupt cutoff or change in direction of the flow.
minus-squareTrainguyrom@reddthat.comlinkfedilinkEnglisharrow-up0·19 days agoAlso I’ve heard that the water that first comes out of those sprinklers is RANK from having sat in the pipes for years
minus-squareIlovethebomb@lemm.eelinkfedilinkarrow-up0·17 days agoIt definitely is. It has a particular smell that doesn’t come out of fabric easily, either.
minus-squarezqwzzle@lemmy.calinkfedilinkEnglisharrow-up0·20 days agoIsn’t the water in sprinkler systems a stagnant mess too?
minus-squareIlovethebomb@lemm.eelinkfedilinkarrow-up0·20 days agoYes. 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.
