If it has a Schrader valve, then there's a very good chance it has a bladder
inside to separate the air from the water. This makes the air cushion last
far longer. I'm not sure of the correct procedure to adjust the amount of
air in the tank; what I've done is to shut off the pump, open a faucet above
tank level, wait until the water stops flowing, then add a burst of air and
see if more water comes out. Keep adding small shots of air until no more
water comes out.
