During a hydrant fire-flow test, water is discharged from a:

• A. Test/pressure hydrant
• B. Loop hydrant
• C. Dead-end hydrant
• D. Flow/test hydrant

Answer: (D)

The test aims to measure how much water the system can deliver and what pressure remains when that water is drawn off. To do this, water is discharged from a hydrant specifically designated for testing the flow—the flow/test hydrant. This hydrant is set up to allow a controlled, measurable discharge and to connect testing instruments (like flow meters and pressure gauges) without unduly affecting the rest of the system. Using a flow/test hydrant ensures the results reflect the true capacity and pressure during a hydrant flow test. Other hydrants described are general distribution or end-of-line types and aren’t designated for the precise testing setup needed to obtain accurate flow data.
