I was talking to Neb the other day and he explained if you dont fill the tank completely, and when you press the top back on...(run on sentence)
Press the top back on only until the Oring starts touching the tube, then turn the tank sideways so the hole (in your carto) is not submersed in liquid. If you have more than one hole punched, dont worry.
Then press the cap the rest of the way on.
This allows the air or e-liquid to pushed into the tank instead of creating a syring like effect and shooting liquid out of the carto or bottom seal.
I also have a "Slap your Mama" thing but this can sometimes make the issue more intnese as it makes the pressure greater inside the carto.
ESPECIALLY with the new Atty Tank....Thats all I will say about THAT! lol (That was for Pete's SAKE!)Which is what you might say when you shoot 2 mls of your favorite E-liquid onto your keyboard!
Not sure if that explains but I will be doing a video later this week explanig this.
