Quick Answer

This section outlines the requirements for piping arrangements in buildings with limited area sprinkler systems. It specifies that if an automatic wet standpipe system is present, sprinklers must be supplied by it. In the absence of such a system, the plumbing system may supply water if it can meet both domestic and sprinkler demands. Applies to building owners with sprinkler systems.
