I used to answer these questions. Now so many people post with so many silly suggestions, I just gave up.
Never over tighten any device. It always eventually causes problems.
Never Remove a Wick unless the unit simply will Not wick properly after a
tank or so. Power off Prime instead.
Never dispose of a removed wick. Next fill it may start flooding and you will need to place it back in.
When attempting to clear a Gurgle - Remember there is condensation/
e-liquid build up in the tube. Place Tip down on a tissue. Blow lightly from connection end. Allow to sit a few minutes. Wipe off and use a Q-tip to clear Drip Tip.
Simple fix for light gurgle - light long draws.
Once familiar with a ProTank, Evod,T3, ETC. - they will rarely show any issues. No dry hitting, no flooding, no needing to be 2/3 full?
Who ever decided that one needs to rethink reason. Why have a 3ml tank that can only vape out 1ml before requiring refilling?
I vape my
tanks DRY without any sign of flooding............Unmodified!
