When flushing open all discharges and flush even the ones that did not flow water during the fire or drill.

When flushing open all discharges and flush even the ones that did not flow water during the fire or drill.

• A. True
• B. False
• C. Only flush those that flowed
• D. Do not flush any discharges

Answer: (A)

During a pump test or drill, you want to verify every discharge path is ready to deliver water. Opening and flushing all outlets, including ones that didn’t flow previously, makes sure there are no obstructions or air pockets in any line. Debris or corrosion can hide in dead-end discharges, and a line that didn’t show flow before may still be blocked. By flushing all of them until clear water flows from every discharge, you confirm the entire system is clean, primed, and capable of delivering the required flow under pressure. Skipping a discharge that didn’t flow before risks missing a blockage that could hinder performance in a real incident, so flushing all discharges is the correct practice.
