What are the major reasons for spitback and how to avoid this problem?

Cause1: The cotton doesn't wrap around the coil tightly enough, spitback and gurgling will occur at the same time in this case;

  • Cause 2: The distance between the coil and drip tip outlet is too short;
  • Cause 3: When the length of the drip tip is less than 3mm, it's easy for the condensation to go into your mouth and will cause spitback, you simply clear the condensation inside the drip tip in this case.
