Which hole feeds house which feeds bladder. Top or side. I know the foot/ snout draws from well. I also can't find manual? Any suggestions? Help ASAP!

I see 3 utilitech pumps, shallow well, deep well and submersible. On a shallow well pump there is only 1 hole for the down pipe and 1 for the out. In a deep well pump there are 2 down 1 up. In a submersible there is 1 up. The pipe that feeds the house T's to the bladder tank. If you have 2 holes at 1 end a 1 at the other, you are trying to install the pump backwards. 2 go down with 2 pipes and a jet fitting before the foot valve. What exactly do you have?
