During the annual test of a pump assembly, flows are controlled by what?

• A. Direct piping to fire line
• B. Flow meters
• C. Approved test devices
• D. Bypass valves

Answer: (C)

During the annual test of a pump assembly, the flow is controlled by approved test devices. These devices are designed and approved for testing, providing a known, repeatable discharge flow that lets you verify the pump’s performance accurately and safely. Flow meters alone only measure what is flowing and do not limit or set the test flow. Bypass valves and direct piping to the fire line can alter system hydraulics or bypass the intended test conditions, which isn’t how the test is standardized. Using approved test devices ensures the test conditions are defined, controllable, and compliant with applicable standards.
