after vapin' a tank down 2 or three times (generally) I just unscrew the base
and take it, coil and all, to the sink and rinse it ALL off nice and clean...
then pull wick, dry burn, rewick, then top off juice, reassemble (never removing coil)
the whole process taking maybe 3-4 min
if I get a
'seeper' (out the afc slots) I just blow thru one side, wipe excess off the other side
and good to go for quite awhile longer...
definitely a pressure/vacuum thing going on when tank gets to less than maybe 8-10%
I always think when the 'cap' comes off the coil and sticks inside the tanks air flow tube
that the whole tank/coil combination is well designed and is a perfect fit (a snug seal)
the alternative would be sloppy and leakage effects...
I've not had this kind of luck, consistency, and pleasure from any other vapin' tank/coil combo - I'm very pleased
ego one - the ONE tank for all
