What is the purpose of a foot valve?
Foot valves can be found in ponds, pools and almost anywhere there is a pump. These special valves allow the pump to stay primed, letting liquid to flow in, but keeping it from flowing back out. The screens or baskets that cover the valve opening tend to get clogged over time, especially in ponds and wells.
Why do I need to replace my foot valve on my well pump?
Running your pump without water in the impeller can cause permanent damage or allow the pump to overheat and fail completely. Replacing your foot valve as soon as possible can save your pump. It will also save you the aggravation of manually priming your pump every time you need water.
Where does a foot valve need to be installed?
The foot valve shall be installed a maximum of 25 feet vertical distance below the suction pipe of the pump inlet. The foot valve screen shall not be supported at the bottom of tank or well for best operation efficiencies.
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 causes a foot valve to not work?
When the system doesn’t hold pressure on the well side I think there are no leaks in piping, check valves, foot valve, pump body. So when a pump still won’t develop pressure I think that there is an impeller, seal, or voltage problem. Sometimes a 240V pump will work at low voltage or even at 120V depending on its design, but will be weak.

When to use a foot valve-common applications and uses?
Use foot valves when you have situations that need a pump, such as when water needs to be extracted from an underground well. Foot valves keep the pump primed, allowing water to flow in, but not letting it flow back out, making them ideal for use in pools, ponds, and wells. How Foot Valves Work
Where do you install a foot check valve?
D. Install foot check valve vertically with arrow pointed up in direction of liquid flow. The foot valve shall be installed a maximum of 25 feet vertical distance below the suction pipe of the pump inlet. The foot valve screen shall not be supported at the bottom of tank or well for best operation efficiencies.
How big of a well do you need to remove a foot valve?
If your water table is deeper than 15 feet, removing the pipe will be easier if you enlist a helper or detach each section of pipe as you pull it out of the well. If your wellhead is plumbed without a union, you may need to cut your water line to remove the well pipe.
