Congrats on quitting the "analogs" so they call em around here. Me personally I have been smoke free for 1 month 1 week and 3 days now and couldn't be happier with my choice. I love vaping and so does my wife. We just recently upgraded to the Kanger T3S tanks and really like them but are having problems with the juices leaking.
Sometimes they work fine other times we get leaks.
Been wondering why that is and have been playing around with them trying to get it just right so it won't leak. Becomes a pain sometimes when you lose a whole tank of liquid due to leaking out all over your hands lol.
I have two T3S tanks, and they seem to leak for a variety of reasons, and both of them you can figure out pretty quick from the gurgle. The first leak I had was due to a bad o-ring on a base, the smaller one that's right next to where the coil screws in wouldn't lay flat on its ridge; I bought a new base and that fixed that. That leak shows up *around* the battery contact.
The other way is if the coil itself is wet, either from too much juice, flooding, or if you've rinsed it out and it's not dry yet; then, if you take the tank off just as soon as you hear the gurgle, you'll see a drop of moisture right on top of the battery contact; either e-juice if it's flooded, or water if it's from rinsing. I've gotten the watery one a couple times, and today, the juice flood, because I dry-burned the coil and put in some new flavor wicks, and primed it with too much juice. So I guess I'll dry burn it again.
Also, and you might have figured this one out already, but it wigged me out BUT GOOD the very first night I owned it -- when you unscrew the base to refill, the coil can come unscrewed, so you need to make sure it's tightened before you put the base back on. This can cause anything from a leak via the coil, to the battery not even registering that a tank is present, and so not firing when you press the button. My iTaste vv3 was showing "non" instead of the resistance of the atomizer as it should be showing.
