Where shall the hydraulic design information sign and semiautomatic standpipe systems be located?

• A. Fire department connection
• B. Main drain valve
• C. Water supply control valve
• D. Pump discharge

Answer: (C)

The hydraulic design information sign and semiautomatic standpipe systems belong at the water supply control valve. This valve is the main point where the building’s water supply to the standpipes is managed, so placing the sign there keeps essential design data (like required fire flow, pressure, and system capacities) immediately available to firefighters and maintenance personnel who may need to operate or verify the system during an incident or test. It also aligns with the way semiautomatic standpipes are controlled—through the water supply valve—so having both the data sign and the standpipe control at that same location makes practical sense. The other locations aren’t appropriate because they’re primarily for external water connections, drainage, or discharge points, rather than the centralized, readily accessible point used to manage and verify the standpipe’s hydraulic design.
