Which hydrant is from which water is discharged during a hydrant fire-flow test?

• A. Riser
• B. Flow Hydrant
• C. Test Hydrant
• D. Post Indicator Valve - PIV

Answer: (B)

In hydrant fire-flow testing, you need a hydrant that serves as the actual source of the flow being measured. That hydrant is called the flow hydrant. The water is discharged from this hydrant to create the test flow, while the test hydrant is typically where pressure is observed and readings are taken during the test. The other components mentioned (riser and Post Indicator Valve) are parts of the hydrant system itself and do not serve as the discharge point for the test. So the water for the test comes from the flow hydrant.
