Which valve takes water from the discharge side of the pump and places it in the water tank, used to refill the tank and can also cool the pump?

Which valve takes water from the discharge side of the pump and places it in the water tank, used to refill the tank and can also cool the pump?

• A. Tank To Pump Valve
• B. Engine cooler Valve
• C. Intake/Compound Gauge
• D. Tank Fill/Recirculating Valve

Answer: (D)

In a fire pump system, the tank fill/recirculating valve is the one that takes water from the discharge side and returns it to the water tank. This setup lets you refill the tank without stopping the pump and helps keep the pump cool by circulating water through the system. That’s why it’s the best choice: it explicitly describes moving water from the discharge back into the tank for both refilling and cooling. The other options don’t fit this role—water from the tank to the pump would be the opposite direction, an engine cooler valve serves the engine’s cooling circuit, and an intake/compound gauge is a measurement device, not a valve.
