Flooding cartomizers in tank?

[FinallyQuit]

Using the madvapes 5 ml syringe mod, and the pre-punched 2.0 ohm cartos sold with it. Following the instructions posted on their site, filled the tank then primed the carto, used for 9 days (that's right, 9 days!!) and flavor dropped dramatically. Changed to a new carto, followed the same procedures for filling/priming, and after 2 days I'm getting gurgles, mouthfuls of juice, and leaking at the battery connection.

Is there something I'm doing that's making it flood? The way I draw, perhaps overheating it with chain vaping, maybe it's the juice (80/20 pg/vg, clear) or could this particular one be bad? It's only the second one I've ever used and the first one was so great!

Thanks for any input.

I've not used a tank from madvapes so I don't know the construction but I figure all tanks operate using the same basic principle.. equalization of air pressure. My carto will flood if there is an air leak somewhere. If it's leaking out the end of the batt connection your carto is flooding and there are only a couple things that could make it flood.. an air leak or the carto itself. Since you've already been using your carto successfully for a couple days I don't think it would be the inner tube puntured. so look for an air leak somewhere, it's not easy to spot, you may have to assemble it and disassemble it several times.

I just got my tank from them today and all I get is gurgles, air flo sounds, and a horrible vape. If you figure out the issue, please let me know donnah. I tried it with a 1.5 dcc and a 2.0 dcc on my kGo and it is just unvapable.

Like I said, I don't have a madvapes tank so I don't know what the parts look like.. but I've heard that dual coil cartos don't do well in tanks, I haven't tried any so I don't know that either.. I'm just starting out myself so I can only advise as to what my experience is and the problems I've had and was able to fix. LOL.. I don't think I'm even qualified to answer this post! The floods I've had using the chibi tank were fixed by working with them until they worked, which meant making sure the top and bottom grommets were sealed.

One thing you can do is when you fill the tank and set it aside to see if the carto is going to flood or not.. set it in a small, shallow cup to catch the escaping juice.. that way you aren't wasting so much juice.

Look at it sitting in there so innocent looking.. you'd never know it dumped a good 5ml of my good juice yesterday! (It's working now)

To be fair, the tank itself is not leaking. The cartomizer is flooding. The air hole punched in it is miniscule. The end is under a flange, and the top is flush with the top of the tank, with a driptip in the end of the carto. I don't think it's supposed to be airtight?

The juice comes up the driptip and out the battery end. That means it's flooding, right?

The tank itself is supposed to be airtight. When I fill my tank with a syringe, I slide the needle down beside the grommet and tilt it a little so that when I slowly fill it with juice, the displaced air can escape. One of my flooding situations was caused by filling too fast and not allowing the air to escape the tank when the juice was going in. When I slid a needle down the side, the excess air came out and the pressure was equalized and the flooding stopped (once I blew the carto out)

if the air is not allowed to escape, it creates pressure inside the tank that forces the juice through the hole in the carto and out the bottom of the batt connector. ideally, when all it working as it should, as you vape, you will occasionally notice air bubbles popping out of the hole in the carto.

Where's tersur when I need him!

Thank you Donnah! That makes sense, and I'll investigate further today. It really bugs me because it WORKED so well, I got spoiled. I'll see what I can do when I fiddle with it. And, worst comes to worst, I'll toss it and try another. . .
