Foot Valve

Foot valve is a type of check valve that is installed at the lower end of a suction line in a pump to maintain the prime of the pump and prevent backflow of the fluid. It typically contains a strainer to prevent debris from entering the pump and causing damage. The foot valve opens to allow fluid to flow into the pump when it is operating and closes to prevent the fluid from flowing back when the pump is turned off, thus maintaining the pump's prime and preventing the need for re-priming. This type of valve is commonly used in applications such as irrigation systems, dewatering pumps, and other systems where maintaining a consistent flow and preventing backflow are essential.

Why Do You Need A Foot Valve?

Foot valve is needed in a pump system to maintain the prime of the pump and prevent backflow of the fluid. When the pump is turned off, the foot valve closes to prevent the fluid from flowing back, ensuring that the pump remains primed and ready for the next operation. This is particularly important in applications where the pump is located above the fluid source, as it prevents the need for re-priming the pump before each use. Additionally, the foot valve typically contains a strainer to prevent debris from entering the pump, contributing to the overall efficiency and reliability of the pumping system.
