Do you need a foot valve with a submersible pump?
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.
What does a foot valve do on a pump?
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.
Is there a foot valve on a submersible pump?
In a submersible pump situation, it is technically called a check-valve because it sits immediately above the pump rather than below, but it is commonly referred to as a foot-valve and works the same way.
Does a pitcher pump need a foot valve?
Generally, you don’t need a foot valve with this pump. However, if you use it frequently and want water without priming, you can install a foot valve at the bottom end of the pipe. A foot valve is a one-way valve that lets water in but not back out again, so it keeps the pipe full of water.
Can a pump work without foot valve?
Without a foot valve water would flow back out of your suction line when a pump is turned off. A foot valve helps to stop your pump from burning out by keeping it primed and is a very inexpensive way to do so.
Can a check valve replace a foot valve?
If the check on the pump fails, it must be replaced. We recommend using only one check valve or foot valve in a pump system. A foot valve should be at the inlet to the suction line of turbine, centrifugal, and jet pumps.
How long does a well foot valve last?
The plastic pipe, usually lasts quite a while. Unless you have an extreme amount on minerals , like calcium, the PVC pipe should last longer than you. It’s the galvanized connect pipes the corrode rather quickly. The foot valve will need replace ment bout every 15 years , give or take a few years.
Where is the foot valve on a jet pump?
A foot-valve is located at the bottom of a well and acts like a one-way check-valve allowing water to go up the pipe toward the house but not drain backward into the well. 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).
Where is the foot valve in a well?
As shown, the foot valve is installed at the pick-up end of the pipe, which is the end that goes into the water well, and through which water is sucked. Thus, it is located at the very bottom (foot) of the well, and so it isn’t easily visible for studying.
How does a Silent Spring assisted flow check valve work?
When the pump is running, the valve is open. When the pump shuts off, the valve closes slightly before the reversal of fluid flow, due to the compression spring force acting on the disc, which nearly eliminates water hammer. Image 3. Silent spring-assisted axial flow check valve
What does the screen on a foot valve do?
The foot valves screen protects the valve and the pumps internal parts as well as the system from harmful debris. The screen slides over the valve and is held in place with screws and acts as a filter for large particles, though a finer filter can be added after the pump.

If your pump cycles on and off when water is running see resource article on “short cycling.” This is not a foot valve issue.
