If you consider pipes between containers to be that long / narrow, the whole structure to be in the air (not vacuum) and edges of the pipes to be 90 degrees as in the picture, assuming the liquid is regular water, the water flow from the tap should be larger than what the pipe could move (if it can move water at all and not bubble clog due to straight edges) – hence the 1 container should be first to fill up
Try filling up a horizontal 3 ml syringe tube drop by drop, you’ll get bubbles, make it meter long and you’ll get a lot of bubbles no matter the water velocity

You are assuming certain tap water velocity without any base.
