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 prevents water flowing out of the pump when the pump is turned off, so the pump does not need to be reprimed when it is restarted.
The function of back pressure valve is to prevent back flow to the pump in case there is an obstruction on downstream side of valve.
the pump supply's the pressure, the resivoir supply's the fluid, the valve dirercts the fluid into the cylinder, to extend or retract the cylinder.
A foot valve is something that you eat with your foot
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 !
To pump air. Acutally, there are many things thant can be done with pressurized air -- even make a computer!
