    Is it an old style in the ceiling or is it a light tan/ grey bottle looking thing on the pipes?

    If it is a newer style than your bladder inside might be bad. There should be a valve on the end that looks like a tire valve. It might have a cap on it. Try to push on valve with a screwdriver. If water comes out than bladder is bad. Only thing you can really do is replace it.
