If you're struggling to reassemble your tap; Take the Tap in your right hand and the Rubber End/ Fresh Dispense Casing in your left. Rotate the Fresh Dispense Casing clockwise to tighten the coils of the Fresh Dispense Line so it fits back into the Fresh Dispense Casing. Then try reassembling both halves, ensure the Fresh Dispense Casing is aligned correctly with the alignment notch on the tap.
