I switched to the 1.8 ohm coil that came with it and it still flooded. Without even using it! Just from sitting there overnight. Turned it on today and went to take a light pull and fluid in my mouth. Yuck! Does leaving these sitting upright promote flooding??
Make sure the coil is completely seated in the base. Unscrewing the tank will loosen it and cause problems. When I put mine back together after a fill the mouthpiece,tank and tube are 1 unit, the base and coil are one unit. I screw the base and coil unit onto the tank and tube unit.
I found if I screw the coils onto the tube and then screw the base onto the coils....leaks and gurgles.
