The test that ensures piping between the water tank and pump can supply the minimum amount of water is the:

• A. Pumping test
• B. Tank-to-pump flow test
• C. Pressure Control Test
• D. Pressure relief valve test

Answer: (B)

Ensuring the tank-to-pump piping can deliver the minimum water flow is what this test checks. It verifies that the suction path from the water tank to the pump—through the pickup, strainer, and any valves or fittings—is sized and unobstructed enough to supply at least the minimum required flow to the pump’s intake. During the test, the pump is run and the actual flow from the tank into the pump is measured under the specified conditions; the flow must meet or exceed the minimum. If it doesn’t, it indicates restrictions or issues in the suction line that could prevent proper priming or cause flow loss. This focus distinguishes it from other tests that assess overall pump performance or pressure control/relief functionality.
