How are people preinfusing with a plumbed in GS/3 (with line pressure at 3 bars)? I currently have my pump switch adjusted towards the far left, almost at the end of the travel range and you'll notice in my video below, when I move the paddle to the center, there is not much water flow because the valve is not fully open (is it to be assumed that this would not be at the 3 bar line pressure?). But as I push the paddle further left before I engage the pump, the flow increases as the valve opens (is it to be assumed that this would be preinfusing at the 3 bar line pressure?). If I want to preinfuse at the 3 bar line pressure, should I be moving my paddle to the far left before engaging the paddle?
