What is the recommended pressure at the most remote standpipe outlet?

• A. 75 psi
• B. 100 psi
• C. 150 psi
• D. 200 psi

Answer: (B)

The recommended pressure at the most remote standpipe outlet is 100 psi. This standard is established to ensure that the standpipe system can deliver an adequate flow of water to effectively combat a fire, particularly in a high-rise building or large structure where distances from the water source to the outlet may be significant. Setting the pressure at 100 psi at the most remote outlet provides a balance between delivering sufficient flow to meet firefighting needs and maintaining a manageable pressure that does not risk damaging the system. This pressure allows firefighters to effectively operate the hose lines while also ensuring that the system remains compliant with code requirements. It maximizes the system's effectiveness while taking into account the hydraulic losses that occur over long distances and through various fittings and hoses. Maintaining a pressure around this level also helps in ensuring the proper operation of fire department connections and hydrants, allowing for smooth integration during firefighting efforts. Overall, this pressure setting is critical for ensuring safety and efficiency in fire suppression operations.
