Which device is specifically designed to manage suction in a water line?

• A. Foot valve
• B. Check valve
• C. Pet cock
• D. Sounding tube

Answer: (A)

The foot valve is specifically designed to manage suction in a water line, particularly in applications involving well systems or pumps. It serves the primary purpose of preventing backflow and ensuring that the pump retains a prime when not in operation. When the pump is turned off, the foot valve closes, preventing water from flowing back into the well. This is critical for maintaining consistent pressure and flow in the system when the pump is activated again. The foot valve typically has a strainer to prevent debris from entering the pump, further enhancing its functional reliability. In terms of functionality, the other devices mentioned serve different purposes. A check valve allows flow in one direction and prevents backflow but is not specifically designed for managing suction. A pet cock is more of a valve used to release trapped air or gas in a system, while a sounding tube is used for measuring liquid levels and does not have any function related to suction management in a water line.
