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.
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'.
To prime a shallow well, first turn off the valve to the water inlet and remove the plug from the pump impeller housing. Pour water through the funnel into both openings and reopen the inlet valve. Return plugs into original position.
5 feet.
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.
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.
The same size as the pipe it is hooked up to in the well.
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.
The foot valve in a well should be the same size as the down pipe, usually 1 inch, but could be as small as 3/4 or as large as 1 1/2 . Foot valves are made in all those sizes.

This would depend on the well type, deep well, shallow well, free flow well - you would need to be more specific. But the basics are: suction tube from the well, check valve to keep well primed, pump, bladder tank to create pressure and that's about it.
