Your having a laugh , bauer couplings on to a suction hose rated at 4 bar max for the return,Bauer coupling on top of the pressure side to prime it , that is a H & S problem from the start, Good luck with a set up like that.
There is not much pressure going down the return hose as its only taking away the excess pressure, the most of it is still going down the main pipe to the field. Agree about the one on top, have you seen it done differently?
