Which item is included as an accessory?

• A. Piping
• B. Suction & Discharge Piping
• C. Valves
• D. Fittings

Answer: (B)

Understanding what counts as an accessory in a pump system helps you see why suction and discharge piping is the best choice. An accessory is something added to support the pump’s operation but not part of the pump’s internal mechanism. The suction and discharge piping are the external connections that link the pump to the rest of the irrigation system; they’re not built into the pump itself and are often supplied as part of the pump package as these attachable interfaces. That makes them the item typically listed as an accessory.

Piping in general refers to all piping in the system, which is broader than just the pump’s connection. Valves and fittings are standard hardware used with piping, but they’re not specifically designated as the pump’s accessory in most specs.
