So I have noticed over the last 2 years of kegging I always have to fight with the "poppit" I think is what it is called. The purge pull tab whenever I keg I have to wiggle them and fight with them constantly to get them to stop leaking. I have replaced them several times and still seem to have the same problem. Is there some easy stupid trick I am missing to make this not an issue? I was to proud to ask but I am getting sick of it. I wonder if there is a way I should be putting keg lube in the underside to help it seal or something like inside the lid pull up the tab and put a drop in there with a cue tip or something. Any advice is welcome as I am so over this issue.
