yeah i have tried unblocking the holes but to no avail. Its funny how it just started happening all of a sudden after a tank rebuild. Ill try your method Wizt and report back, I cant figure out how this can happen, i mean the tank is such a simple device. I wonder if its possible that ive been over tightening the tank slightly, and increased the overall thread length at the bottom of the tank? Its weird though, cos even if i unscrew it slightly its still not right, nothing like my other protank which is newer and works flawlessly.
Its a shame that these quality issues have arisen because i really do like the simplicity, cost and ease of maintenance of the protank. Is there another tank that uses the same coils that is similar in design, but with better construction and build quality? Ive found the protanks to be terribly inconsistent. The first one i bought was great, the second one i bought the mouthpeice hole was too big, bigger than my first one, and the mouthpeice does not fit snug in it, and the third one i bought had the loose mouthpeice issue plus the glass was slightly warped or something.
