So I have been receiving a lot of emails recently about SMOK Tanks leaking and causing damage to the inside of the mods. I too have experienced this problem, and I found some ways to fix this.

First, make sure you always clean your tank and seals well when changing coils.

Next, make sure you always screw your coils into the upper tank portion first, then attach the base and tighten snug but not over-torqued.

Lastly, do not leave it in your car or a hot environment. This causes your juice to get thin and run past the seals and the cotton inside your coil; then it shows up in the base and leaks all over the mod.
