Leaking E-Juice out of your favorite tank? Read this for the answers!

Leaking E-Juice out of your favorite tank?

You just got the hottest tank on the market, and the next day you wake up to find your mod covered in juice, and the tank almost empty. Sound familiar? This happens to every vaper I know, at least once. But luckily the solution is usually simple.

If every part in a quality vaporizer tank is working properly, it should not leak and waste any of your favorite juice. There are some exceptions that will cause any tank to leak, for example if you leave your mod in the sun, but here are some things to consider when trying to figure out why your tank is leaking.

Where is it leaking from? Most commonly, tanks will leak from the airflow holes at the bottom of the tank. This means that too much juice is on the actual coils, gravity takes over and the juice drips down and out of the air holes. It can also leak out of the fill hole, where the glass tank meets the metal base. The most concerning area for it to leak is from the bottom where the contact post on the tank connects with the contact on the mod. If your mod is not regulated and doesn’t contain safety features, this can cause your mod to short out. This type of leaking most commonly comes from the threaded portion of the coil assembly.

When using pre-made coils on most modern tanks, there is a proper way to install the coils and subsequent break in period to keep it from leaking. See a blog post on that here. Virtually every coil uses o-rings to keep the juice in the reservoir. You should inspect your coils before installation to ensure that the o-rings and the threads are in good condition. In addition to that, these o-rings make it difficult to thread the coil entirely on. Tighten the coil on with a paper towel so you have extra grip to make sure it is fully seated. Most leaks that do not come from the air holes can usually be traced back to a degrading o-ring or rubber seal.

Over time, the cotton around the coils tends to break down. This cotton cannot be changed, and the entire coil must be replaced. The slow break down of the cotton will cause increased juice flow and consequently the tank will leak. This is a good sign to change your coil, as following this degradation the cotton will lose contact with the coil and cause it to hot spot and burn. This is what causes that awful metallic taste when your coil goes bad.

If after all this you still cannot find the cause of your leak, it is possible that wear and tear or a hard drop has increased tolerances causing it to no longer be air tight. In this case, the tank should be replaced for the best experience.
