You'll have to excuse my total ignorance on this subject. When we read of various crew members busy trying to manage the "pumps" to "dewater" flooded portions of the ship's various flooding compartments is there a separate pumping system at play here that's different from the bilge pumps?
A bilge pump is exactly what it says. I can think of only two places a bilge pump could discharge. Overboard or into another bilge. I can't think of any reason why they would discharge into the firemans passage.
