Its not telling you to install 50 ft. of pipe from the suction flange but it is saying that you can only install a listed OS&Y valve within 50 ft of the suction flange.

Is this a typo? What it the reasoning for having such a long run of pipe without valves? In a small fire pump room with a bfp, It would seem you would have to do a bunch of zig zags with the pipe just to meet this requirement.
