The Subtank Mini are great tanks but there is one problem that a lot of people are experiencing, they leak. Which doesn’t mean it’s defective or broken, it more then likely just doesn’t have a nice vacuum seal inside which causes the juice to slowly seep out. No worries though, a quick clean up and bit of dental floss should do the trick, here’s how I fixed mine:
Step One: Unscrew the Subtank from your mod. Baby steps…
Step Two: Unscrew the glass from the base and rinse out the tank using warm water.
Step Three: Unscrew the coil from the base and check to make sure the small rubber ring (the clear one) are still in tact. Also, check the larger black O-ring on the base of the Subtank, it should be securely in place and not damaged.
Step Four: Slide the glass tube off of the tank exposing the two black O-rings.
Step Five: Remove the bottom O-Ring from the Subtank and check the top O-ring for any damage or misalignment. The bottom O-ring is typically the cause of leaky tanks. Clean the bottom O-ring in warm water and check for any defects.
Step Six: Wrap some dental floss around the bottom grove where the O-ring sits. This will puff out the bottom O-ring ever so slightly creating a tighter seal. Make sure the dental floss sits flush against the tank with no visible wrinkles or twists.
Step Seven: Put the bottom O-ring back on making sure it covers the dental floss we just added. Carefully slide the glass tube back on the tank. If it doesn’t slide on easily you may need to remove a layer of the dental floss. Be sure the O-rings are aligned properly and create a solid seal.
Step Eight: Put the coil and base back together being sure they also create a juice tight seal. Add juice and enjoy.
Hopefully that worked for you and everything is all fine and dandy once again (:
