Want this question answered?
A foot valve, in relation to a water well, is a check valve at he bottom of a well to keep the water from running back into the well from the pump when the pump is not running. If the check valve does not hold the water the pump will lose it's prime and will not pump water.
It will only work properly if you put it very close to the foot valve. In which case you may as well replace the foot valve - it's not difficult to do. If you put it at or near the pump, the pump will just suck air.
A shallow well jet pump sits on the ground next to the well. To install it, connect tubing to the intake side of the pump and put a foot valve on the end of the tubing to control the water. Lower the foot valve and tubing into the well. Remove the drain plug on the pump and pour water in it to prime it. Replace the drain plug, connect the pump to power and turn it on.
When the check valve failed to seat properly at the lower unit in our well, the reserve tank would drain down quickly and then the pump would run again and again and again, . . . If you have a valve between the pump outlet and the tank you can turn it off to check operation of the tank. Most likely your valve has failed. It did this very often until we had the entire mechanism in the well replaced and installed a submersible pump. No problems since and the submersible pump is hardly audible compared to the old pump motor which was mouted near the well head in the basement. Good luck.

If the bladder tank is not holding water then you may have a faulty check valve on top of your deep pump. Splits in the pumpdrop line down the well are also common. -The bladder in the tank can also be faulty. -You must tell us ALL symptoms , not just ask about two things you've heard names of. Best solution - call a well tech , NOT a plumber !
More to the point is finding how the air is getting into the system. If you have a jet pump ( surface pump/motor unit) I would suggest checking and properly tightening every fitting between pump and foot valve. If you can't do this call a well technician.More to the point is finding how the air is getting into the system.

If you are using a jet pump you must have a good foot valve, then remove the prime nut or gauge from the top of the pump and fill the pump and pipe with water. You may have to do this a number of times to get all the air out of the system.
You will have to dig the well deeper and adjust the length of the pipes to reach the water where the foot valve or pump is.
Are you sure you don't mean 'foot valve' - this is the valve at the bottom of a well suction pipe when you use a jetpump. I've never heard of 'foot trap'.
You pop the seal and see if it closes properly. If there is any doubt at all, it's easy to change. - If you are operating a jet pump and it won't prime, the foot valve ( just a different check valve ) is always suspect.

Your pump or foot valve could be very near 'static level'. It may need to be lowered. But many other factors could be at work such as a fault in pump or pressure system.
well obv its a pump and you step on it to pump it up lmao! Just to add little more detail to the above answer that someone submitted, a foot pumps works by allowing air to pass through a valve and then pushes it in another direction... I guess by going through a smaller opening it expels at a greater force. Hope that helps a little more...
