I'm working with the evod tank and when I would refill it when I first got it the tank was fine. Now when I go to refill it juice flows out of the drip tip. If you are familiar with this tank then you know that you have to refilling it from the bottom so I have to turn the tank upside down. I don't know if this is normal or not because when I first got it this didn't happen. It just started happening recently.
