Remove the tank atomiser from the battery, if you can, block the hole in the centre of the thread on the atomiser, your little finger should just about do it, while it is blocked, blow hard through the mouth piece, even though you have blocked the hole you should still be able to blow air through as it will come from 2 little holes you will not be able to see because of the skirt on the tank atomiser body. If there is no air when you blow then either these 2 little holes are blocked.
yep done this and no air flow - can i fix or will it need to be returned?
