Hi again Chillin
What can I say but welcome to
vaping. Actually with a bit of experience most of these problems are fairly easily overcome. First I suggest examining your tank closely and try and figure out how it works. Knowing how it works helps a lot in figuring out what is going wrong. A tank is a sealed unit with holes at the bottom and when filled with
juice the juice will naturally stay in place if the holes are small enough and no air leaks into the space above the liquid. Same principle as a pet rodent water bottle uses. The holes though are actually too large to properly hold in the juice, all by itself the juice would leak out while air bubbles found their way into the tank through the same holes at the same time. The juice dosen't leak out because there is cotton wicking in front of the holes to provide just enough resistance to the juice flow to balance it out and keep the juice in the tank. As you vape juice out of the wick it is replaced slowly while air is allowed back into the tank through the wick.
Understanding that balance needs to be maintained to prevent leaks then leads to to ensuring a couple of things. First the tank needs to be sealed at all its joints. That has you examining for o-rings, the condition of o-rings, the mating of the parts of the tank, and keeping the top filler portion closed and sealed. That includes making sure your coils are sealing at both their ends. If the TV12 is like the BB & CB then there should be an o-ring at both ends of the coil though I believe the top one is actually on the bottom of the chimney.
Try testing various pieces for a seal by putting water in your tank and blowing into it to pressurize that space. You can test some of the seals this way. Water won't hurt anything as long as it dosen't get into your mod.
Try replacing the o-rings with your spares. Too long in an atty will have those silicon o-rings taking on the shape they are being compressed to, once moved the shape no longer fills the voids and you get leaks. Don't throw the original o-rings out as they will over time regain their proper shape and can be reused again. Be careful when stretching the o-rings out of and into place over top of what are usually pretty sharp threads so as not to damage them.
The other problem can be with the cotton in the coil. When you build your own it is a fairly common problem but is less so with pre-made coils. That's why folks are suggesting trying a different coil in it.
Also get yourself at least a 5 ml syringe with a fat blunt needle as that will make it much easier to suck juice out of tanks for things like this.
