There water squirts through the venturi, causing a larger volume of water to return back up the larger of the two 2-line jet pump pipes and onwards into the building water system.
The difference is that a 1 line jet pump's venturi is above ground, while the 2 line jet pump's venturi or injector is down in the well.
