Hello folks, new to this site and this game really, i cant get my head around this problem....

Ive been working on an Infrico Bottle cooler, these are prone to the cappilary blocking up due to the break down of the crap driers right, so.... when you come to reclaim the gas you can't reclaim it all due to it being blocked, i am right, if so how would you go around reclaiming the rest off the gas which you cant get to without cutting the pipe, i might sound wrong but any help would be great thanks alot
