Which accessory is used to draw water from an external source into the pump system?

• A. Sensors
• B. Tanks
• C. Enclosures
• D. Intake Structures

Answer: (D)

The key idea is the interface between the water source and the pump: an intake structure. It sits at the external source (pond, river, lake, or well) and provides a controlled entry point for water into the suction line, often including screens or gratings to keep debris out and devices to regulate flow. This is what allows the pump system to draw water from outside sources.

Sensors, tanks, and enclosures serve different roles—sensors monitor conditions, tanks store water, and enclosures protect equipment—so they aren’t used to pull water into the system.
