Yep. Too many incident reports of leaking/damaged standpipes that were concealed from visual inspection, never tested or exercised.

When concealed from view, there is no way you tell if a dry manual standpipe is damaged or lost integrity unless monitored somehow.

Is this intent correct…even for a manual dry standpipe? It seems to me that the dry standpipe supervision requirement should be coming from NFPA 14 based on the standpipe class and intended building use, not from 72. Requiring air supervision could create prime conditions for intra-pipe corrosion for an otherwise normally-empty piping system. Am I missing something? Thanks, Ryan L.
