I can’t insert the tube into my Perfect Draft keg
Inserting the tubes into the tap unit can be tricky, so try these 2 things and if you are still unsure please let us know!
Wet the tube beforehand
Clasp the end of the tube with your fingers to make it circular and not creased when inserting, then wiggle it into the tap unit
Try a different tube, the current one could have a fault
Remove the bottom metal spout on the tap unit before inserting the tube
