Even thought of buying another just for the drip tip.
You can take the screw out. Nothing will leak except the condensation that forms and goes down the air tube. Nothing will come out of your tank.Can you do that while there is liquid in the tank? I don't know much about this tank as I just got it. What does that center copper screw connect to? I ask that because I am not sure if it has to be screwed all the way in, or if it's one of those tanks where that can be unscrewed to adjust for different mods.
