you somehow posted 4 duplicates lolDetails drawing into the working of the 10 ash ejectors can be found in RMS TITANIC Owners Workshop Manual or TITANIC The Ship Magnificent books. I do have a photo of the item on my iPad but has gone the blink for now to enclose. Will enclosed when fixed. It does raise an interesting question as ash ejectors where used on RMS Aquitania very similar size ship to Titanic. Yet could be used to remove water as well with the bilge pumps to. As for Aquitania could shift 4,500 tons of water per hour as for Titanic 170 tons per hour with bilge pumps only. I may be bit unfair with Titanic as lessons learnt from her loss, could of well had a change plan! Or was just the plain fact the Aquitania was built to Admiralty standards?
