Which statement best describes a Wet Standpipe?

• A. Continuously pressurized with water from a public supply
• B. Filled with pressurized air and activated by opening a hose
• C. Not connected to a public water supply
• D. Requires manual filling

Answer: (A)

Wet standpipe systems keep water in the piping at all times and are connected to a reliable water supply so the system is continuously pressurized. This means when a firefighter opens a hose outlet, water is immediately available without any delay from filling or pressurizing the line. The other descriptions describe different standpipe types or conditions—one where the pipe is not filled with water and relies on air pressure, or one not connected to a public water supply, or one that must be manually filled—none of which match a wet standpipe.
