7.5.4 Dry standpipes shall have only a single level of interconnection. You can't interconnect on both the top and bottom of dry standpipes.

Is this requirement intended to apply to manual dry standpipes? NFPA 14 does not appear to make a distinction in this case, but if they're intended to prevent circulation, I would imagine that is not a concern with a manual dry system. Steve, are you on vacation yet? This one is up your alley. Thanks for your time.
