Allowing too much liquid to enter this tube can flood the atomizer and cause a leak through the bottom of the tank or liquid through the mouthpiece. If the atomizer head is not tightened securely to the base, excess liquid may also leak through the bottom and out of your tank. All parts must be assembled securely to ensure that there is no leakage through the glass, the atomizer head, or the base. Please ensure that all o-rings/seals are seated properly as well.
