We are in Birmingham at the moment and the fire brigade still maintains the doors to drop suction hoses into the cut, I have often wondered if these doors would ever be used. Instead of stopping to open the door and push the hose through, aren't firemen more likely to just throw the end over the rail? DaveD No, because the ''hard suction pipe'' would then be higher than the impeller of the pump trying to lift the ''open water'' & the whole operation would be harder to achieve. Plus the fact that I seem to remember that a theoretical lift of no more than 28 feet is possible. Don't ask me what that is in metric---I'm an Imperial boy & always will be. We had ONE metrication lecture in 1978 that lasted for precisely 32 minutes!!! The Fire Engine I used to drive had an embossed notice on the sun visor that stated, ''This appliance has a height of 3,300 mm.'' Not much use when I'm wondering if I'm going to get under a 10' 6'' bridge up ahead!
