What is the function of the foot valve?

Overview: A foot valve is a type of check valve that is typically installed at a pump or at the bottom of a pipe line (hence the name). Foot valves act like ball check valves, but have an open end with a shield or screen over it to block debris from entering the line.

Does a well need a foot valve?

Nearly all well pumping systems, one line jet pump, two line jet pump, or submersible well pump, require a foot valve installed at the bottom of the well piping. The strainer prevents picking up large debris that could clog or jam the foot valve in its open position (or that might damage the water pump itself).

Where is the foot valve on a well?

The foot valve is off the bottom.The foot valve is below water level.My well is about 25ft deep until it comes to water level and the the foot valve is below water about 15ft.The only thing that is not new is the long pipes going down the well.Can you help?

When to use a foot valve in a jet pump?

A foot-valve is only used in a jet-pump situation (where the pump resides above ground and shoots some water down the well to help lift more water back up).

What is the function of a foot valve in a centrifugal pump?

Foot valves are either made of PVC plastic or stainless steel, and they are known for keeping the continuous presence of suction within the pump. Foot valves are used to maintain hydraulic pressure to keep the water flow in accordance with the given settings or configurations.

Why do you need a check valve on a well pump?

Closing the check valve prevents water in the well piping from falling backwards into the well when the pump has stopped running. We need this function to keep the well piping and water pump filled with water – otherwise the well pump may lose prime, leading to loss of water in the building.

What is the foot valve of a water pump?

Foot valves are a form of check valve, a valve that only admits flow in one direction. In the case of a foot valve, fluid can be pulled into the valve and up the line, but it cannot flow back out. When the pump is on, water moves through the valve, into the line, and into the pump itself.

What is a water well foot valve?

A Well Piping Foot Valve is a one way or anti-siphon valve which is installed on the pick-up end of the water pipe near the bottom of the well. The foot valve prevents water from flowing backwards out of the jet pump and well piping back into the well when the jet pump stops operating.

What is a plumbing foot valve?

As you may guess, a foot valve is basically a check valve combined with an inlet strainer (visible in our page top photograph). The strainer prevents picking up large debris that could clog or jam the foot valve in its open position (or that might damage the water pump itself).

What is foot valve?

A foot valve is a component used with a pump to help the pump stay primed, ensuring that when people turn it on, it will immediately begin pumping water.
