What is the minimum water pressure required at all points in a distribution system during fire flow?

• A. 30 psi
• B. 20 psi
• C. 40 psi
• D. 5 psi

Answer: (B)

In a water distribution system, particularly during fire flow scenarios, maintaining adequate water pressure is critical for ensuring effective firefighting efforts. The minimum water pressure requirement is established to ensure that adequate flow can be delivered to fire hydrants and that sufficient water is available for fire suppression activities. A minimum of 20 psi is typically required at all points in the system during fire flow to provide enough pressure for firefighters to effectively operate hose lines and equipment. This ensures that water can be drawn from the hydrants quickly and efficiently, allowing for the rapid suppression of fires and minimizing potential damage. While pressure levels above this minimum can provide even better performance, a regulation of at least 20 psi is often seen as the baseline standard in ensuring safety and efficiency during fire emergencies. Higher pressures may not be necessary for all parts of the distribution system, but the 20 psi benchmark is crucial for the operational readiness of emergency services.
