He's replaced the pump... fitted it the wrong way? Looks ok to me but a thought.
Or incorrect wiring from the pump missing a wire.
Whoever did the install fitted the pump pumping down not up so it won't naturally clear itself of air, once it's vented it will be fine but sometimes they can be a pest to vent.Or incorrect wiring from the pump missing a wire.

I don't think there is a filling loop as such the round vessel looks to be an air separater of some kind and the pipe going up is probably a combined feed and vent ? Would that be correct op ? You have a small tank in loft ?
