ProTank 2 tips, and I do use the PT2 on my MVP.
1. Check all your silicone rings and make sure they are all there. They easily disappear when cleaning....kinda like the sock monster in the dryer.
2. Swap out the manufactured wicks for cotton. I use cotton used to do leg wraps on horses (sterile), boil it, dry, and pull into wicks.
3. Turn the "cup" on the stack above the head upside down.
4. Make sure your base, head, and tank are all SNUG. Check the stack to make sure it is set in snug on your head
5. The vacuum created in the tank will quit working well once the ejuice goes down to the level right above the wicks. Refill or clean at this point.
6. When you refill your tank, wipe the stack and base of any juice, blow your drip tip, and run a pipe cleaner or something similar down the draw tube inside the tank.
7. If using a new head, put a few drops of juice on your wicks to saturate, or pull some dry hits off re-assembled tank without any power to draw the juice into the wicks.
8. Use Kangertech heads.
Try that and see how it goes. Made a world of difference for me
