I'll starty by saying that I am completley new to the vaping scene. I bought my first e cig about 5 years ago, and many more after that trying to find a viable solution to my smoking problem. My kitchen junk drawer is pratically an e-cig boneyard, various types of batts, chargers, attys etc. Anyway, I gave up on vaping for years and just recently came back with my Ego-C starter kit purchase. I made a totally seamless transition from smoking a pack and a half a day, to my ego C.
Back on topic, I love my Ego-C, it worked great for me all weekend untill I went back to work. Halfway through the work day, the damned thing dumped its entire tank into my shirt pocket.
I went home, removed the hard plastic tank cap and replaced it with a soft rubber one, everything ran fine untill I was at work the next day, then it dumped again.
I work in a highly scientific/analytical career, and in keeping with my analytical nature, I decided to do some research of my own to identify the cause.
Was I over-filling? No..
Was the tank solidly attached to the atty with no leakage around the atty stem? Yes..
So heres what I discovered, and I've tested this and proved it. I dont know why no one else has come up with it. Anyway, the tank is hermetically sealed except where the atty pierces the tank right? So basically what I found was at about 72 degrees ferenheit(regardless of fluid ratios), this thing ran like a champ, however at about 80 degrees ferenheit, pressure began to build in the tank, and that added pressure was forcing liquid through the atty's "breather" holes found on either side of the penetration needle, but not around the needle/tank connection. I took the entire system apart and just left the atty stuck into a tank with a rubber cap, and to prove my theory, I ran a type K thermocouple into the center of the tank, I then began to heat the tank slowly with a space heater untill the core temperature reached 80 degrees ferenheit. Suddenly, as I had suspected, I heard some small sloshing noise, and saw the draw through holes in the atty relieving the built-up pressure through the draw through holes carrying a goodly amount of juice with it, which will also flood the atty cone, the battery, and eventually, your pocket.
I tested the tank pressure using a digital monometer at 72 degrees, and found it to be pretty close to atmospheric 14.2in, but as I increased the tanks core temperature, eventually reaching 80 degrees, I noted a 3in rise above atmospheric, and that is way more than enough to push juice through the atty and into your pocket.
If you work in an office, this things the bomb, but I work mostly outdoors, and being in Texas, we usually start breaking the 80 degree barrier around mid January.
The solution would be for the lab guys in Schenzheng to go back to the drawing board and re-design the system to be completley airtight by way of a sealed one-way valve that would open to allow draw-through when puffing on it, and seal airtight again when the negative pressure(sucking) ceases. This would allow the system to work as it was originally designed, and would prevent future leakage issues as then both the tank and atty are equalized in pressure, therefore the pressure has nowhere to go.
I hope this helps shed some light on why you still have severe leaking, even though you have a perfectly good tank. Untill the design is modified, there is no solution from what I can tell. so really.
