When must plans for a standpipe system be submitted for approval?

• A. Before the installation of the system
• B. During installation
• C. After occupancy
• D. Never

Answer: (A)

Plans for a standpipe system must be submitted to the Authority Having Jurisdiction for approval before installation. This upfront review ensures the design complies with NFPA 14 and local codes, covering factors like standpipe type and arrangement, outlet locations, hose connections, water supply and pump requirements, riser sizes, valve placements, and coordination with other life-safety systems. Approving the plans before work starts helps prevent design or installation mistakes, allows necessary permits, and avoids costly rework. Submitting during installation or after occupancy would bypass this critical check, and “never” is incorrect because plan approval is required.
