Tearing apart the carto won't help us solve your flooding problem. It could be caused from a quality control issue with the carto itself, but usually it is user error.This weekend I picked up a tobacco flavor e liquid in the same brand. 100% VG it is light and no where near as thick as the grape. Now I am having flooding issues again! If I gut one of these cartos and post it here can you gals/guys tell me what the h is going on? Please and thank you
Were you extremely careful to not get any juice into the air hole while filling the carto? I put a wooden tooth pick into the hole to insure no juice gets in there.
I also use a tank tool such as the Slap-Yo-Momma tool inserted on the carto when putting it into the tank for filling the tank with juice. This insures no juice gets in the air hole during this step.
Did you fill the tank before putting on the top endcap on the tank? Doing this would cause flooding after putting the top cap back on.
