Foot Valve Manufacturing
A foot valve is another type of check valve. As its name implies, it is installed in a pipeline or pump’s bottom. It has a similarity with a ball check valve characteristic. However, foot valves have an open-end installed with a screen so debris and dirt cannot enter the pipeline.
In order to avoid heat loss, the foot valve’s opening is larger than the line. A foot valve is commonly installed in a pool, ponds, and other applications that use a pump.

If you are working in an application that uses a water pump, a foot valve is a must use.
Foot valves are designed to avoid any damages to your water pump due to dry runs.
Considering the functions of a foot valve, like in the water pumping systems, if the water pump is turned off, it can prevent the water from flowing back.
Therefore, your pump is still primed for the next time use.
Here are some manifestations that you need to replace your foot valves:
- If your electric bill becomes higher than usual, it may indicate that you have a faulty foot valve that needs to be replaced.
- If the foot valve is leaking, it needs to be replaced.
- Water sputtering in your home.
- Fluctuating water pressure.

Foot Valves: The Ultimate FAQ Guide
In this guide, you will learn more information about foot valves.
From its materials, types, benefits, applications, and cost, all the details are here.
Here are the different materials used for producing foot valves:
PVC foot valves are commonly used in a pond or pool. These are cost-effective and lightweight types of foot valves.
However, PVC foot valves are not suitable for applications that used chemicals, high pressure, and high temperature.
Bronze foot valves have a different working temperature, working pressure, and testing pressure.
Suitable media for bronze foot valves is only water.
Stainless steel foot valves have a higher corrosion resistance than any other materials.
Another distinct quality of a stainless steel foot valve is its high chemical, high temperature, and high-pressure resistance.
It is commonly used for potable water supply systems and sometimes in the food and beverage industries.
Cast iron foot valve is a heavy-duty type of foot valve.
It is usually used in water suction hoses and other related applications.
Plastic foot valves are long-lasting and durable. It is also used for drinking water applications, pools, ponds, and more.
However, just like PVC, it is not highly recommended to use for chemical and high pressure/temperature applications.
Brass is also a common material used for making a foot valve.
Brass has a low to no lead content so it can be applicable for drinking water systems.
Foot valves are a one-way valve type. This means that the foot valve is only open in one direction.
Because of that, it can only be used for unidirectional flow. Foot valves are used so that pumps will stay primed. Thus, it can let the liquid flow in without flowing back out.
Suction can be formed as soon as the water pump is running thus, pulling the water through the pipe in an upward direction.
The foot valve is specially designed to open up easily so it won’t be damaged due to incoming water pressure. Hence, foot valves can deliver a normal water flow.
However, if you turn off the pump, the pulling force is also released. Thus, the water will flow downwards making its entire weight pushed onto the foot valve.
Good thing, a foot valve is a one-way check valve and cannot be opened in a downward direction and is shut tightly.
Because of that, the pipe is sealed off completely and preventing a flow back. By using a foot valve, you can avoid energy waste while protecting your water pump from damages.
Both foot valves and check valves are specifically designed to prevent the water from going back through the pipe when the water pump is turned off.
Also, foot valves and check valves have similarities in their characteristics. In order to distinguish foot valves between check valves, here is the list of their differences.
- Foot valves are installed at the bottom of the pipeline as an inlet of a jet, centrifugal, or suction pump. Meanwhile, check valves are positioned after the pressure tank.
- Check valves also maintain the pressure of the pipe and the pump.
- Foot valves have a distinguishing feature like a strainer in its open end while the check valve is assisted by a spring.
Usually, it is recommended to use only one-foot valve or check valve in a pump system.
Foot valve clearance from the bottom of the well is very important in order to avoid the good pump from picking up debris, dirt, and mud.
The recommended distance of the foot valve from the bottom should be 5 feet or more.
Yes. Most jet pumps usually have a foot valve.
If your well is shallower than 27 feet, you can use a pump without a foot valve.
Foot valves will fail usually because of leaking. Another factor for a bad foot valve is because the power stays off for a longer time.
If your foot valves are faulty or leaking, it can cause the water to flow back to the bottom of the well making it lose its prime.
The price of a foot valve varies from its materials and size.
Foot Valve Cost by its Material
Plastic Foot valve’s price ranges from $16 up to $20.
Brass Foot Valves’ price ranges from $18 up to $42.
Bronze Foot Valves price ranges from $32 up to $120
Stainless Steel Foot Valves’ price ranges from $41 up to %53.
Cost of Foot Valves Based on its Sizes
¾-inch foot valves price ranges from $16 to $32.
1-inch foot valves price ranges from $17 up to $48.
1 ¼-inch foot valves price ranges from $17 up to $32.
1 ½-inch foot valves price ranges from $20 up to $88.
2-inch foot valves price ranges from $19 up to 120$.
Installation and replacement costs can be determined through the depth of your well.
Shallow well less than 25 feet deep costs $100 up to %150.
Moderate well ranging from 25 to 100 feet costs $300 up to $600.
Deep well more than 100 feet deep costs $2000 up to $5000.
A foot valve is consists of different parts that include the strainer, valve body, seat, and disc. Although, there are different kinds of foot valves, here are their common parts:
All foot valves feature a strainer that is attached to its open end. It is designed to prevent sediments, muds, debris, or dirt to enter the pipeline.
A foot valve strainer is usually made up of materials like brass, plastic, and stainless steel. This strainer can increase the life span and performance efficiency of the foot valve.
The valve body is the most important part of a foot valve.
The materials that are used for a foot valve body typically include brass and cast iron for heavy-duty applications.
PVC and stainless steel foot valve bodies have a compact and smaller structures. These are ideal for low-pressure applications.
If you turn off the water pump, the foot valve body lands at the seat. Thus, it is also an important part of a foot valve.
A rubber or silicone O-ring is positioned at the foot valve’s seat to avoid leaking.
A disc functions as the door of a foot valve. The disc raises if the water pump is turned on and when the water starts to flow upward.
The disc of a foot valve is commonly made from steel, brass, bronze, and other super-grade materials.
There are several types of foot valves including:
Spring Type Foot Valve
In a spring-type foot valve, a spring is used to hold a poppet. The inlet side of the foot valve carries pressure that forces the spring to contract and the poppet to open.
If the pressure releases, then the poppet will be back to its normal position. A spring-type foot valve can be installed either in a horizontal or vertical position.
Flapper Type Foot Valve
Flapper-type foot valves function through gravity. One side of the foot valve opening has a leather flapper, rubber, or a disc.
A flapper-type foot valve is forcefully closed if the fluid’s weight above the flapper, gravity, and pressure combine.
Mostly, a flapper-type foot valve is installed vertically. However, if the flapper is closed, it can be installed horizontally.
A check valve is not a recommended alternative for a foot valve when used in your well’s pump.
Check valves are usually positioned at a water pump discharge site. It helps in maintaining the pressure.
Also, a check valve is not a good alternative to foot valves because check valves can increase friction. Thus, you must use a foot valve instead of a check valve for your good pump application.
It is very important to consider these factors before installing a foot valve for a trouble-free operation.
Pipe Flow Velocities
You need to consider the pipe flow velocities and make sure that your foot valve has an appropriate size.
Whether it is for a high flow or low flow, it is very important that the size of your foot valve is according to the flow velocity.
All foot valves have different pressure ratings. Thus, it is important to calculate system pressure before installing a foot valve.
- Before installing a foot valve, make sure that your water pump is thoroughly cleaned.
- Also, make sure that the foot valve doesn’t have any damages or defects.
- Take notice of the foot valve’s spring-loaded poppet mechanism. Make sure that it is operating freely.
- Install the foot valve in a vertical position. Make sure that the arrow is pointed up accordingly to the fluid flow. You should install the foot valve with a 25 feet distance below the suction pipe.
Note: Consult a professional for installing your foot valve.
The life span of a foot valve depends on its usage and materials.
A typical foot valve can last up to 15 years and more.
You can increase your foot valve’s life span by proper maintenance and cleaning.
Proper installation and appropriate usage can also increase the life service of your foot valve.
All foot valves are very good to use. Each foot valve has specific applications depending on its material.
PVC foot valves are the ideal choice for applications such as pools, water pump systems, ponds, and more because of their lightweight and cost-effective properties.
While metal foot valves such as brass, bronze, and stainless steel are a good choice for applications that deal with chemicals, high pressure, and high temperature.
Using foot valves entails many advantages especially to water pump systems.
- Foot valves can conserve energy.
- It can protect your pumps from damages.
- It can increase your water pump’s life span.
In this guide, we have gathered some tips and techniques if you are using a foot valve.
- Check your foot valves if you notice that your shallow well doesn’t have water. The foot valve may need a replacement.
- Please take note of the arrow indicating the flow direction. Make sure that your foot valves are installed following the arrow direction.
- You need to know the cracking pressure of your application before installation since foot valves are designed with a specific cracking pressure.
- When choosing a foot valve, take into consideration of the water hammer. The fluctuation of the water hammer can damage piping systems depending on the velocity.
- Clean and maintain your foot valve regularly.
- PVC foot valves are used for wells, ponds, and pools.
- It can also be used for hydraulic pumps.
- Foot valves are also used for industrial applications like pneumatic pumps.
- Car wash systems
- Rural fire protection
- Municipal water treatment
There are several standard requirements for foot valves based on their materials.
For cast iron foot valves, it should comply with ASTM A-216 standards.
For stainless steel foot valves, they should comply with ASTM 18-8 requirements.
A foot valve is available in 3/8-inch to 36-inch sizes.
You can contact your manufacturer for your specific size applications.
A typical foot valve has an NPT end connection and a strainer on the inlet side.
The answer is yes. A foot valve must be installed at the well piping bottom in a submersible well pump, two-line jet pump, and one line jet pump.
A foot valve is very important especially in applications that require a water pump. A foot valve can prevent backflow of the water so your pump stays primed.
A properly installed and maintained foot valve can protect your pump against damages thus, extending its life span.
Each foot valve has a specific application depending on its size and material. You can choose PVC, bronze, stainless steel, or cast iron foot valves.
Also, please take note of the factors that you need to consider before buying and installing a foot valve.
