The hydrant used during a fire flow test to read static and residual pressures is a:

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

Answer: (A)

For a fire flow test, you need to measure static pressure with no flow and residual pressure while water is flowing. This requires a hydrant designated for testing—the test hydrant. It is set up with the proper test connections and gauges so you can obtain accurate, repeatable readings without altering the rest of the system. The other terms describe where a hydrant sits in the water network or its typical usage, not the purpose of the measurement setup. A test hydrant is specifically used for taking these pressure readings, which is why it’s the correct choice.
