Flooded in my AGR tank. Leaked out the bottom. Had to remove it and replace with my Boges. Hated to do that but had no choice. any sugggestions?
I'd hoped that someone with more experience with the Raven as well as the AGR tank had answered... but perhaps just some tech info can help you find a possible solution. I don't have an AGR, so I'll assume you've assembled it correctly with the Raven ( one user had not that I can recall ). I'll also assume it just isn't one bad Raven, it does happen but not a lot, obviously none of the following would take that into account. So in short, these are only some of the possible causes when nothing is technically wrong with the AGR or Raven itself.
Hot weather will make many atty's, carto's, clearo's and tanks leak simply because the warmer a liquid gets, the thinner it is and the easier it flows. So if it was hot where you were at... try it in a cooler location. I've had several of other types of vaporizers, when left in a hot car... start leaking.
A thin ( viscosity wise ) liquid in general will leak more than a thicker one. While we usually just think of the PG/VG ratio when trying to determine the thickness of a juice... other factors such as added ingredients like distilled water or alcohol which are commonly used to thin a juice can also come into play.
When filling a tank... you also must take care to not accidentally pressurize a tank using a bottom coil designed carto. On the AGR, you should simply be able to open the top fill screw to help lose any excess pressure it may have. This next part will sound a little odd after that last comment... but if you remove the drip tip, and invert the tank ( use a napkin on the top to catch any juice ) and gently blow into the bottom connector... it can also help "reset" the carto itself and get rid of any excess juice that may cause it to gurgle etc.
Overall, what I've experienced and what others have reported about the Ravens... you should expect more flavor than compared to a standard fiberfil type of carto. The reports overall have been very favorable. If you got more than one, try the other Raven to see if it was simply a "bad" one that you had tried first... if you didn't get but the one, don't give up on them... it still may end up being a favorite for you.
