When service testing a fire hose, it is necessary to:

• A. Have access to a water source that is sufficient for charging the hose
• B. Use only a pressure gauge
• C. Test without water to measure elasticity
• D. Ensure the hose is dry

Answer: (A)

During service testing, you’re confirming that a hose can be filled with water and charged to the required service test pressure without leaking or failing. Water is the medium that reveals leaks, weak spots, and potential ruptures under pressure, so you must have a water source capable of delivering enough volume to completely fill and pressurize the hose. A gauge alone cannot substitute for actual pressurization with water, and testing without water doesn’t reflect how the hose will perform in service. Keeping the hose dry isn’t the goal of this test—the essential requirement is access to a sufficient water source to charge the hose.
