On the second one the pressing down on the lid technique worked really well - took about 10 seconds to fill the syphon tubing. This time I didn’t burst the ballon either so just left that attached for the first 8 litres. Which made it a bit simpler. I’ve tried pressure a return gas loop before and never really manage to get it to work unfortunately.Just another thought (sorry) if you connect the gas post from your corny (gas flushed) to your FB you will equilibrate the pressures and possibly (if you have a little pressure in the corny) have enough pressure to bleed the beer Syphon line.
I think based on your suggestion I’ll have another go sometime - will need to pick up some extra tubing though.
I’m really chuffed that the severity of ‘learning experiences’ today has been quite mild .
