Thanks for the update Jim. It's not something I would have thought about but I have heard of 'getting your own back' before and, with Trevor's comments, realised about water pressure. It's perhaps something I could have asked about when I toured the submarine in the submarine museum at Gosport but there is so much to see anyway and details don't come to mind at the time.
