Hiya! I have that exact same problem! My tanks are spitting out hit liquid into my mouth!
I quit cigarettes 5 weeks ago thanks to
vaping. The first 4 weeks ran smoothly, no problems whatsoever. But then on week 5 everything went wrong.........
Now every time I vap a spray of hot
e-liquid goes in my mouth, just like what you said Umzungu! but my tanks have started leaking into my battery as well!
Its very frustrating coz I don't know what I'm doing wrong, I've been really careful not to over fill. But it must be my fault coz its happening will all of my tanks (Kanger MT3, Kanger E-Vod, Vivi Nova & CE4 V3) (I'm using a normal eGo type battery.)
I'll try blow through from the battery end as you suggested jSquared. All the leaking & drinking e-liquid is driving me crazy, its so wasteful. I can't understand why it all went wrong in week 5?
