Ok so yesterday I unscrewed the bottle to refill! When I screwed it back in, the o ring somehow wedged itself halfway inside the bottle so I unscrewed the bottle to attempt to realign the o ring! After several hours of fiddling with it nothing I did fixed it properly. So I had the brilliant Idea of removing the cap from the tube! Bad bad bad idea! Now I have two problems, can't get the o ring in the cap right nor can I figure out how to put the cap back on the tube! Any advise would be appreciated!
