Closing off your airflow when refilling tanks. ???

[Simon G]

Ok, here's a thing .... topfill tanks always cause stock coils to flood a little, take for example the nautilus 2, before I had seen a review for that I mentioned to @bix_vapes that the only issue I could see with that tank was filling it like that would cause some flooding/gurgling ... and low and behold the first review I see from Phil Busardo he mentions that the coil goes a little gurgly after filling. Bottom fill tanks never do this, so there must be something about the pressure in a tank when it is fully assembled that isn't there when the top is open.... without a doubt that is the case.

I'm not sure if closing the airflow at the bottom effects this in anyway, but I suspect it does.

Got to say this has been one intresting science lesson, I close it off purely by habit then tip my tank upside to then open the airflow. I do this on every tank I've owned whether it leaks or not.

Here's a thought would your tank work in space [emoji28][emoji28]

Ok what if VG is thicker than water so can be held back by smaller amounts of pressure, then the airflow down the chimney when the bottom airflow is turned off air is flowing down then has nowhere to go so is flowing back up again, this could be acting as a pressure barrier stopping juice flooding the coil, when the airflow is open air flows from top down the chimney out the bottom airflow pulling juice out the tank the same way as taking a hit thus creating flooding maybe but IV had a few [emoji23]

Iv'e had some of my best ideas when i'v'e been drunk. At least they seemed good.

However, your hypothesis assumes that air is significantly affected by gravity and would tend to fall through this tube. I don't think air flows down a tube, just because it is there. Hold a smartie tube in front of you and feel the bottom. Is the air falling through this tube and out of the bottom ? I don't think it does. Air tends to move from areas of high pressure to low pressure. Otherwise it just sits there.

I'll stick to the drinking then buddy [emoji23] [emoji482]

The question is, Does the air pressure change, inside the coil, when the airflow holes change from open to closed. I don't think it does and therefore makes no difference as to whether a coil is going to flood or not.

I am shamelessly bumping this thread in the hope of more discussion.

I think it's ritualised behaviour. All the while the chimney is open to the atmosphere it can make no difference

I must admit, that conclusion was the point behind making this thread. But, however and it is a big but.......

These things don't usually come out of nowhere and so I am still really interested to know how it came to be such commonplace advice. I may be missing something obvious and my lack of experience of the vaping world means I must keep an open mind. I still hope someone with the knowledge of the history of this thing, might come here and show us all what it's all about.

I got the Griffin 25 out of the box and set it up last Friday. Coiled wicked and filled her up with some lovely aerovape macaroon.... forgot to close the airflow at the top. 2 mls or so of juice poured straight out the bottom airflow. "Balls".

When I had the kangertech toptank I use to always close it got the aspire cleito and does not matter if you do or don't you still get the air bubbles I got the new serpent tank the other week it's the one you can use pre built shop coils and that in the instructions says make sure it's closed on filling
