What is the difference between a foot valve and a check valve ? Which type of valve should you choose?
Foot valves and check valves are essential components in fluid pipelines, particularly in industrial applications involving water pumps, chemicals, or fluids requiring flow control. However, many people may be confused about the differences between these two valves and how to choose the one that best suits their application. This article will help you clearly understand the differences so you can choose the one that best meets your needs.
– What is a foot valve?
Foot valves , also known as skull valves, are devices used in plumbing systems. They are often installed with water pumps to control the flow of water in the same direction and allow the pump to pump water at a lower level than the main unit to be stored in a water storage tank . Installing a foot valve ensures that the pump is constantly supplied with water and can pump water efficiently the next time.

– What is a check valve ?
Check valves , also known as non-return valves, are devices that are often installed with water pumps and other pumps, but can also be used with PVC or brass fittings for plumbing and sanitary applications. The function of a check valve is to help control water flow in the same direction without reverse flow. The check valve has a valve that acts as a blocking valve to prevent water from flowing back, helping to prevent damage to the pump or water pump.

Difference between Foot Valve and Check Valve
Although both devices can be used in water pump systems, there are some clear differences in their use. The foot valve, with its main function and benefit, is to prevent water from flowing back into the system. Meanwhile, the check valve’s main function is to prevent pumped water from flowing back into the system and to prevent water shock within the pipes, which could result in damage to the plumbing system.
Selecting both Foot Valve and Check Valve
The principle of selecting a foot valve is to select a foot valve that is at least one size larger than the pump or water pump. For example, if the pump is 1 inch in size, the appropriate foot valve should be 2 inches in size to achieve maximum efficiency. It should also be selected to suit the type of work, such as wastewater treatment systems or residential water supply. Plastic foot valves should be used, which are more resistant to corrosion.
When selecting a check valve, choose one that fits the plumbing pipe or is slightly smaller. It’s also best to choose a check valve made from plastic, brass, or rubber that is corrosion-resistant and rust-proof. This will ensure a longer service life and increased efficiency.
