A foot valve is a check valve, typically installed at the bottom of a suction pipe or well, that prevents water from flowing backward when the pump is off, thus keeping it primed.
Features
 :- Prevents Backflow: The primary function is to maintain a water column in the suction line, preventing water from draining back into the well or source when the pump is off. 
- Durable Materials: They are made up of Polypropylene, which offer good resistance to corrosion and wear, especially in well systems. 
- Easy Installation: foot valves have self-tapping threads for easy installation. 
- Cost-Effective: Compared to other types of valves, foot valves are generally more affordable. 
Applications
 :- Used in Pumps, Well pumps, Water treatment plants, Industrial applications, Agriculture
