FOOT VALVE Meaning and
Definition
-
A foot valve is a type of check valve used in plumbing systems that is designed to prevent backflow of water or other fluids. It is typically installed at the end of a suction pipe or hose connected to a pump, particularly in applications where the pump needs to draw water from a well or other water source.
The foot valve is named as such due to its unique shape resembling a foot. It is usually made of durable materials such as metal or plastic to ensure longevity and resistance to corrosion. The valve consists of a hinged flap or disc that can freely open and close. When the pump is activated, the fluid pressure causes the flap or disc to lift, allowing the fluid to flow through and reach the pump. However, when the pump is turned off, the flap or disc quickly seals shut, preventing the fluid from flowing back into the source.
The primary function of a foot valve is to maintain the prime in the pump, which refers to the process of keeping the pump filled with liquid to ensure consistent operation. By preventing backflow, the foot valve ensures that the pump does not lose its prime even when it is not actively pumping water. This is particularly important in applications where the water source may be located above the pump, such as in a well or a vertical pipe.

Etymology of FOOT VALVE
The word "foot valve" is a compound word consisting of "foot" and "valve".
The term "foot" in this context refers to the lower part of the leg in humans, specifically the part that allows us to stand and walk. In the case of a foot valve, "foot" refers to the design of the valve, which resembles a foot or, more specifically, the shape of a human foot. The valve typically has a wider body or base, resembling the sole of a foot, tapering upward into a narrower neck or spout, resembling the leg and ankle.
The term "valve" comes from the Latin word "valva", meaning "a folding door or leaf". This evolved to refer to any device that controls the flow of fluid or gas by opening and closing a passage.
