Depends on where it is leaking from, and if the chamber is flooded. If wick is over saturated,
juice can drain out the drip tip. Tilting a flooded chamber up, while
vaping, is one way to clear/vape out the excess, that can happen when first filled.
If it is a clone, the o ring that secures the pop up build base, can sometimes push down, creating a leak where the stem a funnel meets. Especially if your wick tails are not properly trimmed, and drag the chamber a tad when securing the
tank.
Properly wicked, maintained and assembled, it shouldn't leak. But identify where it's leaking from and why, is half the battle.
Vape long and Prosper.!!!
