Can anyone tell me what the max. required amount of torque or operating force that needed to open the main valve/operating nut on a underground Mueller fire hydrant(200-300 ft. lbs ?) and where I can find that info.
Also, does anyone know the requirements, F.A.A. or otherwise for the location requirements for fire hydrants on an airport airfield/runway and where that info is found?
Thanks
