Well the trick of flipping the rubber gasket worked for 2 tanks but this morning about 8ml of juice came out. Luckily I have been putting the tank into a Pyrex to protect my mod and counter but yeah, bad design.
It has to be that the top just becomes loose over time, maybe the press fit pin on the swivel it the weak spot. Not really sure but at this point I am done fucking with it. Too bad too, it vapes great, a tank I really enjoy using.
Vapergate should really have new rubber gaskets made up with just a plug, remove it, fill with juice and plug the fill port back up. Send them out to all the customers free of charge. At this point I will not buy anything more from vapergate unless they make this right, it's a damn $60 tank.
I am going to post this in the other Dumptank threads to warn people of the problem, mine was working well for awhile but now something must have come loose.
