After playing with the sprinkler a bit, I've noticed two areas where they could be improved, in my opinion.

1) They slow down pawn movement. I had assume sprinklers were roof-mounted like in real life, but I guess they're on the ground, because they seem to slow down pawns (unless I'm imagining it, in which case, my bad). This makes them inconvenient to place in high-traffic areas like hallways.

2) They're kind of fragile. So they can be somewhat ineffective in the places that actually need sprinklers the most, when they are needed the most, like when an explosion goes off in volatile storage, or combat areas under attack. Maybe this can be resolved by allowing them to be "stuffed" like pipes so stronger versions can be made for more hazardous areas?
