Where do i start. Ok i will start with the pretty lady after all Ladies first.
Totally Hemp it just happened to me yesterday i have 5 of these tanks and some are in use not all of them.
I also noticed one leaking at the bottom cap and im familar with tanks what i did was turn tank around and switch caps and it still leaks.
For me personally as i like to change out the ce2 to my desired ohm i did this to another stone tank
Now it took a day but i found juice where the grommet meets the tube after a few hours.
To combat that i wrapped white water teflon tape around the o-ring 3 times on the grommet and there it is fine now.
These caps that come with the tanks evidently are not foolproof yet and hopefully there is a revision soon.
Like i said i even put that leaking cap on the other end of the tube and same thing happened.
Scribes yeah they worked fine with my first tank full of juice then learned i had to fiddle with it to get it to work properly.
The ce2s top porcelain cap has a little play it can move up or down a tiny bit .
What works for me when i get gurgling
I blow through the mouthpiece to clear airtube,
I remove mouthpiece and clean the resevoir of juice thats right under the mouthpiece.
The i pull "up" gently on the porcelain cap until,it goes no further - reason for this is if it slips on the tube a little downwards when you put tank back together the silicon cap will not meet the top metal cap and juice gets into the coil area when held in horizontal position and the gurgling begins as the airtube get juice into it.
So pull up "gently" on porcelain cup until it stops.
Lube silicone nipple a little with juice and line up the notches woth the wicks and place it over the coil gently or you will push it back down again.
Screw place cover over nipple and screw it slowly so the silicone cover does not turn.
This all seems like a hassle and is a little of a fuss but i find this works for me.
I still once in a while have to blow out the tank and clean the resevoir with each tank full but it works really well for me .
Also i find that that rated 2.0-2.2 ohn ce2 just give me a burnt taste no matter what on my megalodon and since have swictched it to a higher ohm ce2 and i get a great taste with my 100% pg that i vape.
Sorry for the long post but if it can help some folks great.
