This may not be the reason your tank in particular is leaking but I'm pretty sure it's why mine was. I just feel the need to share my experience with everyone here, maybe it will help a person or two.
I'd been having a leak free experience with the tfv4 up until a couple days ago when i took the tank apart to clean it. I filled it up and ended up with juice leaking through the air holes onto everything around me even though I wicked it the same as I had been for a month or so. I chalked it up to being tired and took it apart, washed and rewicked... It leaked again! I was very tired at this point and put a store bought coil in and went to bed.
After that I changed how I was wicking quite a bit but wasn't getting a good vape, too many dry/burnt hits, so tonight I decided to recoil and rewick.
Thats when I noticed the problem, when you clean the tank and all the o-rings have no juice on them, there's a chance they stick as you screw the rba head on and bunch up. I noticed on one side the o-ring stuck up into the juice channel and left a giant hole right into the air flow! No wonder it leaked so fast and heavily, I may as well have had no o-ring on the rba head, haha.
A couple drops of juice on the threads and the o-ring to make sure they didn't stick as I threaded the rba section in, rewicked as I had before the leaking catastrophe, and all was right in the vaping world!
HTH
