What is Foot Valve? Properties, Uses and Application

Foot Valve

Foot valves are an essential component of a piping system with a submersible pump, helping to prevent the pump from losing its prime and causing damage. Despite its significance, foot valves are only sometimes fully understood by all users and operators of a piping system. This blog will discuss what a foot valve is, its properties, uses and applications. We will provide a detailed guide on using a foot valve to ensure your piping system works effectively and efficiently.

What is Foot Valve?

A foot valve is a type of check valve, or one-way valve, used in a water supply line. It prevents the backflow of water from the system back into the pump while allowing flow in one direction. Foot valves are typically installed at the base level of suction pipes to provide an adequate seal and protect the pump from damage due to loss of prime.

Foot Valves Properties:

Unlike regular check valves, foot valves have a strainer or filter basket that helps keep debris out of the pump, allowing clean water or any other liquid to pass through. The basket is removable, making it easier to clean or replace, and comes in different mesh sizes depending on the type of liquid being pumped. The valve also has a rubber seal or gasket that creates a tight seal around the basket and helps to prevent leaks.

Foot Valves Uses:

Foot valves are commonly used in submersible pump setups for irrigation systems, fire protection systems, and other applications requiring a continuous liquid flow. They also prevent siphoning when a pump needs to be primed frequently. Additionally, foot valves are ideal for use with shallow wells and when the water table is low, as they ensure the pump is always primed.

Foot Valves Applications:

Foot valves are commonly used in agricultural irrigation, hydraulic, and fire protection systems. They are an effective way to keep pumps primed, ensuring a continuous flow of fluids and preventing the need for frequent maintenance and repairs. They are an ideal choice for homeowners pumping water from a shallow well and commercial and industrial systems that require a reliable flow of liquids.

How to Use a Foot Valve

To use a foot valve, it should be installed in the inlet end of a submersible pump setup. The strainer or filter basket should be cleaned or replaced periodically to maintain an uninterrupted fluid flow. It is also important to ensure the valve is installed in a level position and primed before use. It is recommended that the valve is installed with a strainer with double the inlet size to ensure there is no restriction to flow.


Foot valves are an important component of any submersible pumping system, essential in maintaining a constant flow of liquid while protecting the pump from damage. We hope this guide has provided valuable information on the properties, uses and applications of foot valves. If you have any further questions, don’t hesitate to contact your pump supplier or consult a qualified professional. Remember, a properly installed and maintained foot valve can make all the difference in ensuring a reliable and efficient pumping system.
