Hello, I have been vaping for around 3 years now and have gone through a few mods. My current setup is a TFV16 tank on a Smok Majesty. As of recent my mod has been leaking for an unknown reason. I have quadruple checked for crossthreading and even replaced the triple mesh coil. I have rarely had issues in relation to leaking but I am using my back-up glass for it but have done so for around 6 months. The o-rings show no rips or damage in general. When the leaking happens it doesnt happen initially, instead it tends to soak up and then bottom out through the air flow. Any ideas on the issue? Thanks in advance.
