I've had this tank for about a week. (the coil version not the mesh version) Had leaking/flooding/mouth full of
juice issues since my first build. Went to all the reddits etc, tried the press-fit fix, messed with all kinds of coil setups, all variations of wicking etc. Still getting a mouthful of
juice and leaking through the airflow holes.
This is what fixed it for me. Replacing the small clear o-ring inside the fill cap. The factory installed one was really cheap and janky and kindof flat rather than round. The o-ring from the baggy is noticeably thicker and rounder.
After installing the o-ring from the baggy I can even overfill just a little and never a single drop leaking out. Now I realise this tank is very forgiving with wicking and coil placement, doesnt seem to matter now with regards to leaking. Bad seal allows
juice to flow from the juice fill holes and into the mouthpiece.
If anyone is still having this issue I would suggest replace this o-ring first, then try the press fit method, then look at your wicking.
