Which locations should pressure gauges monitor standpipe system pressure?

Which locations should pressure gauges monitor standpipe system pressure?

• A. Main drain connection only
• B. At the base of the standpipe
• C. At each main drain connection and at the top of each standpipe
• D. On the exterior of the building

Answer: (C)

Pressure in a standpipe varies with elevation and along the piping, so you need gauges placed where they’ll reflect the true pressures firefighters will rely on. Placing a gauge at the top of each standpipe shows the pressure available at the highest point and any loss through the vertical run, which is what matters for the furthest/discharge point. A gauge at the main drain connection at the base provides a reference of the system pressure at the source and is essential during charging, testing, and maintenance to verify the pump and piping are delivering adequate pressure and to detect leaks. Together, these locations give a complete picture of the standpipe’s operating pressure.
