Water may be delivered to a fire pump by the following means.

Water may be delivered to a fire pump by the following means.

• A. All of the above
• B. By suction only
• C. By gravity only
• D. By discharge only

Answer: (A)

The water that feeds a fire pump can enter the pump in several ways depending on how the system is designed. Water normally enters via the suction side from a water source such as the public main or a storage tank. If there is an elevated storage tank, water can be delivered to the suction by gravity, helping prime or maintain flow into the pump without relying solely on the pump’s suction. In some setups, water can also be introduced to the pump through a discharge-connected arrangement or via another source that pushes water toward the suction, effectively delivering water to the pump from a different path. Because all of these delivery methods can be used in different NFPA 20 installations, the correct choice is that water may be delivered to a fire pump by any of these means.
