Every day our phone rings asking us if we have a particular valve. Usually, the answer is yes. We try and keep the warehouse full of choices. This article will give an overview of the Foot Valve and the Discharge Valve.

In irrigation systems, a foot valve and a discharge valve are two different types of valves that serve distinct functions:

1. Foot Valve: A foot valve is a type of check valve that is typically installed at the end of a suction pipe or at the inlet of a pump. It is

   designed to prevent water from flowing back down the pipe when the pump is turned off or when there is a loss of pressure in the system. The foot valve includes a strainer or a screen to prevent debris and large particles from entering the pipe or pump, ensuring that the water source remains free from contamination. The foot valve allows water to flow into the pump or system while preventing backflow when the pump is not in operation, helping to maintain prime and preventing damage to the pump.

2. Discharge Valve: A discharge valve, on the other hand, is a valve used to control or regulate the flow of water in the irrigation system. It is typically installed on the outlet side of a pump or at various points in the distribution network, such as mainlines, lateral lines, or individual zones. The discharge valve allows the operator to adjust the flow rate or shut off the water completely in specific sections of the system. This enables precise control over the water distribution, such as varying the flow to different zones, adjusting for changing water demands, or facilitating maintenance or repairs in specific areas without disrupting the entire system.

In summary, the key difference between a foot valve and a discharge valve lies in their respective functions. A foot valve prevents backflow and ensures the prime of a pump, while a discharge valve regulates or shuts off the flow of water in the irrigation system to allow for control, adjustment, or maintenance purposes.
