Am I correct in understanding that you've never used this tank, but have only watched the video about it, or did I misunderstand your first post?
Even when I use the correct filling technique (with a syringe with plenty of room for air to escape through the fill hole) the cartos still flood. They start off working fine, but after a few draws, it's run for the hills, lads - the flood waters are here.
I think the OP's point about a draw issue may be the problem. Going to work on that a bit tomorrow and will post my findings.
Thanks, hazozita for your added input, that adds more information to help come up with a solution if there is one. It's true, I don't own nor have I seen an AGA. However, realizing that cartotanks function basically the same way despite manufacturer or design, I was trying to add my knowledge and experience into this.
Cartotanks are basically juice carriers. Basically have a tube and two endcaps, with holes just large enough to allow a cartomizer fit inside. That's all.
These all work on the same principle. Air and liquid pressure within the tank itself is what feeds the cartomizer. The act of vaping creates suction within the cartomizer, and creates negative pressure in the tank until the air/liquid pressure equilizes what juice was drawn by the vapor.
Things that upset the pressure in the tank can be the sudden increase of pressure by adding the top cap, whether it is a cartotank or the AGR design. For the carto to flood, it means there's too much pressure in the tank, or the vapor is using an incorrect puffing technique.
During your trial and error to find the solution, since there appears to be too much pressure in the tank, open the juice fill screw and allow some air to leave. (If I had a needle, I'd use that and withdraw some air.) This should equalize the tank pressure and prevent further flooding.
If the vapor is power vaping or chain vaping, too hard of pulls can suck too much juice into the carto. Tanks need a gentle, slow, patient draw quality of 3-6 seconds length.
