I've been hearing rumors that the kayfun tanks have summer heat leaking issues. If anyone could shed some light on this it would be much appreciated as summer is fast approaching. It's no rumor - it's a quite strong possibility that your Kayfun tank may leak, summer or not. The Kayfun platform (and those modeled after such) are vacuum tanks, and are dependent on the relationship of pressure inside the tank to that inside the chamber in order to feed the wick properly. **The key element to insuring this operation continues without constant headache - ensure ALL o-rings in the tank are in good order and creating the adequate interference with their mounting surfaces in order to create an air tight seal. Believe it or not, o-rings do wear, especially those in areas that experience frequent abrasive stresses from opening/ closing/ tear down/ rebuild of the tank. Along with making sure o-rings are properly sized & functioning, you'll want to make sure they're well conditioned and pliable. Pipe Butter is a perfect solution for conditioning all of your o-rings; a dry o-ring is a ripping, tearing, leaking o-ring.
In elevated heat environments, the pressure increases inside the tank, and this can often push additional liquid into the chamber, possibly overwhelming the wicking, then exiting the chamber via the air feed. If the o-rings of the tank are not properly fit, this increased pressure will seek any weakness available in an attempt to regulate, and may also lead to leakage from the lid, tank sections, base, and, in the case of the newer V3 and V5, at the base of the build deck.
What can the avid Kayfun user do to mitigate as much of this issue as possible? 1) Consider the addition of the o-ring upgrade under the (+) deck/ around the center post, as discussed HERE. 2) Make sure **ALL** of the o-rings are in good shape and well conditioned (you've got the tank apart anyway), and this includes the most often overlooked o-ring - the small one in the lid. 3) Dress up your wicking. This is the first line of capturing liquid from the tank, and while inadequate wicking will lead to a poor vaping experience, it will also become quickly overwhelmed with changes in tank pressure and allow the tank to leak. 4) When filling your tank, never fill completely to the top - a small pocket of air is necessary not only for the tank to regulate and feed correctly, but also provides a bit of expansion should the tank become heated. Taking a quick puff or two from the tank should then help the tank to resume normal operation. 5) Simply don't leave your Kayfun in direct sunlight/ enclosed in a hot car, etc. As with any other important device, a bit of conscious care goes a long way. Although I did leave a number of KF tanks in direct sunlight, sitting on the dash of my Tahoe last summer in order to test & proof the o-ring upgrade, I don't recommend it, as you wouldn't treat any other valued product susceptible to such conditions.
All of this being said; the elephant in the room that can't be overlooked is poor manufacturing/ machining processes. I've had $20 tanks that ran as well or better than $100 tanks, and I've had others that weren't worth a dime. Some machining issues can be overcome if the user is ambitious enough to narrow down the flaws and address each. Often, it can rapidly become more trouble than it's worth - especially for the new vaper, such as the Kayfun V4.
I hope this has been of some help/ always available for questions or discussion.
