I think I'm a slow learner. I took the top off my 7ML LavaTank yesterday and filled it. When I put the top back on, it forced tons of liquid into the cartridge, and of course some leaked out the bottom into the well on the Provari. Cleaned everything up, and it took quite a while (sucking juice all the while) to get things back to normal.
Today when I needed to fill the tank again. After taking the top off, I pulled the tank up just above the hole in the cartridge and filled it. I then put the top on the tank before pushing the tank back down on the cartridge, and WALA, no cartridge flooding.
This is probably common knowledge to most, but I learn the hard way.
No harm to the Provari from the leaking. I do thing that the battery connection on the Provari is sealed, but that's just my thoughts.
