What is an alternate methodology to perform flow test on fire mains without hydrants?

• A. Branch lines
• B. Hose connections
• C. Inspectors connections
• D. Low point drains

Answer: (B)

When you need to test how much water a fire main can deliver but there aren’t hydrants available, you want a discharge point that you can flow water through and measure. Hose connections provide exactly that: portable, standard outlets on a fire main or standpipe where you can attach fire hoses and run water into a meter or gauge to determine flow rate and pressure. This setup lets you simulate hydrant-type flow in a controlled way, giving you usable data about the system’s actual capacity and performance during testing. Branch lines are part of the protected system and aren’t configured to provide a single, measured test discharge. Inspectors’ connections exist for testing, but hose connections are the practical, readily portable method that creates a measurable flow path when hydrants aren’t present. Low point drains are for draining water from the system, not for conducting a flow test.
