I did a search and couldn't find this elsewhere, so I apologize if I'm not the first to mention it. I started a new atomizer for my 801 yesterday and it leaked at the mouthpiece and battery end to the point that I thought it might be faulty. But I managed to fix the problem by removing the cartridge, then pulling the white liquid container off of the black mouthpiece itself. (No worries here. The white container has a bottom on it, so any liquid in the container will not drip out when removed.)
I wiped off the entire outside of the container, and ran the mouthpiece under water to remove all excess e-liquid. I removed the excess water from the mouthpiece by blowing through the wide end and wiping the inside with a Q-tip. I snapped the container back into the mouthpiece, the cart back into the atomizer, and viola...no more leaking.
I think e-liquid has a tendency to be...I dunno...self-wicking?...due to its oily base. So once it does start leaking due to overfilling or whatever, it will continue to do so until it finally dries out on its own or with a little help.
