How To Prevent a E Cig Tank From FloodingG
You can prevent your E cig tank from flooding if you want to stop the gurgling sound from happening. Most people think they can squeeze every drop of e liquid into their tank. But this only results in the tank flooding and leaking out all the juice onto the battery.

1) Don't over fill the tank to much. There will always be a fill level printed on the tank outside. Never go above this and also make sure you don't go below it or you will place strain on the coil.

2) When filling the tank, don't place the liquid in the middle were you suck on it. Try to get the liquid around it so that it fills up on the sides.

3) Try not to make the tank stand up upside down for long periods of time. This will cause all the liquid to get inside the middle bit causing a major flood.
