Have you ever experienced the moment that you find your tank has leaked? Your hands are stained by greasy juice with sweet honey toast smell. People around are looking at you, wondering how will you cope with this mess. If you are really unlucky, your trouser pockets get stained as well, while you know what it is and you may not be embarrassed initially you just know you are going to meet someone sooner or later, and you don’t want to attract everyone’s attention before you can change your trousers. Here are some approaches that may save you, your e-juice, and your trousers.


The improper tank filling

When filling the tank, make sure you don’t spill the e-liquid over the glass tube. If you did this accidentally, wipe off the liquid with a paper towel, or it may gurgle and leak. Slope your tank when filling up, this action ensures that the juice goes the inside of the glass (or plastic) of your tank and stays away from the central tube. As the atomizer has fills up, straighten your tank slowly and try not to spill any liquid. Don’t overfill your tank, the air space will create a vacuum in the tank to retain the e-liquid in the chamber.


Tighten your tank up but not over-tighten

A tank that is unscrewed sounds a very basic but hilarious reason for tank leakage, but it often happens. Gaps between the coil and the base of atomizer, or the tank and base can cause a leak. The solution is to re-attach the atomizer head to the base and the base to the tank. The atomizer head sometimes may loosen when unscrewing the tank, so you have to check it if you don’t do anything specific with it. You may also encounter ‘cross threading’ when you screw two components together, and they fail to line up properly and leave us with the risk of an unsealed tank. However, don’t over-tighten your tank by putting too much strength into it, otherwise the O-rings are likely to be damaged. The solutions are check, check, and check again.


Replace your O-rings

The O-ring is a rubber ring usually placed at the top and bottom of the tank. If the O-rings are damaged, there is no airtight seal and the juice will leak out. You can buy new O-rings to replace old ones. Occasionally, not all the O-rings can fit securely on your tanks, which can cause unwanted gaps as well.


Don’t leave the vape in a horizontal position

If you carry vape devices around in a horizontal position, your tank may leak as well. This is because when a tank is laid on its side for a certain periods of time, the e-juice may leak through airflow holes. Especially when the e-juice is under half full, the juice holes in the coil are no longer covered with juice and it is easy for the e-juice to leak. What you need to do is to be careful of the position to place your vape.


Choose the right coils

Occasionally the coil fails to absorb the e-liquid, which may lead to tank leakage. Vapers might use faulty coils in their tanks, or the coil is too old to work efficiently. Most tanks come with replacement coils with other resistances, which offers various vaping experience.

High resistance coils have smaller juice holes, which is ideal for higher PG juices as they can flow easily. Or, higher VG juices vaporize at higher temperature. It means that if the liquid can’t vaporize properly, liquid leakage can happen.

Low resistance coils have bigger juice holes and airflow holes, which allows thicker liquid to run through. What is likely to happen if we put thinner e-juice in low resistance coils? The liquid may lead to flooding, either in the central tube, or out of the airflow holes.


Inhale correctly

It’s best to inhale softly and slowly. The inhalation style could be one of the reasons for tank leaking, especially when you keep meeting such issue or are used to smoking. If you draw firmly or sharply on the vape devices as you do on the cigarettes, you may pull the liquid faster than the coil can vaporize. The excessive juice may flow into the tube, and leakage results. Instead of drawing firmly and sharply, you can attempt to draw gently and longer, though it takes time to change your former habits.

Another hidden reason is long and condensed draws. You can hardly inhale all the vapor when you press the fire button and take a draw. The remaining vapor can condense into the centre tube day by day. You may never know which drop will be ‘the last straw’, and to avoid this happening:

  • Inhale as soon as you press the fire button
  • Remove your finger from the fire button when you are not inhaling
  • Clean your tank on a regularbasis

Maintain your vapes regularly

I would suggest cleaning out your vape devices if you notice the flavor and vapor production have decreased, or more visually, your tank gets dirty. This usually takes 1-2 months, depending on how often you vape. Since e-juice can exist in the tube, such as the line between the glass and base hardware, which can impact the air seal of the tank. You can rinse the tank in cold water and letting it air dry overnight. Or, you can consider to change the new coil if the leaking still happens after vape maintaince.


Empty your tank during a flight

My fine point pen once leaked on the plane. Though I only go for good quality and brandy pens, this situation still happens, not to mention vapes and vape juice! You definitely don’t expect your tank to leak everywhere and smell delicious when you share a tiny space with hundreds of other people on the plane. What if your neighbors notice your vape device and assume that it may explode during the flight? In some restrictive countries and areas, you are likely to get arrested! So, don’t take the risk of getting into unnecessary trouble during your travel or business trip, and don’t forget to empty the tank before boarding. The main reason for both pens and vape tanks to leak on planes is the change in pressure in the plane cabin. It is different from when you are on the ground so it can often cause pens and vapes to leak.


Use Aspire leak resistant tank

You may feel confused after looking through articles about how to prevent your tank from leaking, the simplest approach is to purchase a leak resistant tank.

Aspire has launched a series of vape devices which feature childproof and leak proof attributes. The devices are the Aspire Tigon Tank, for instance, and the Aspire Reax Mini Kit. The silicon leak proof seal is around the fill port. As for the TPD version, the self-sealing function can allow you to fill the tank with a needle filling bottle.

The Aspire AVP pod also has leak free filling in the bottom of tank, and because it’s magnetically attached, the pod can click back to the device conveniently. You can’t change your coil; however, you can replace the whole pod. This is super simple for vape beginners.

In addition, Nautilus 2S Tank features in child resistant and leak proof. After filling the juice, you can push the top cap back and turn clockwise to screw it. It’s almost impossible for the juice to leak due to cross threading.


Take care! The following two tips may cause dry hits! If you combine all of them, you should beware!

Increase your power setting

Excessive e-juice is one of the most common causes of leakage. The main reason is that there is too much juices in your coil to vaporize, if so, the juice may leak. The most direct way is to increase the power to higher voltage settings, which can vaporize more juice as you puff. BUT, you should be aware of dry hits when you set the power too high. You don’t want that awful burnt taste or even to ruin your coils, do you?


Fill with higher VG juices

As we have discussed above, VG is thicker than PG, so the VG-based juices flow much slower. It means the liquid has less chance to enter central tube from the coil. To some extent, increasing the ratios of VG in the e-juice can avoid tank leakage. Again, be aware that high VG liquid can easily cause dry hits that destroy the cotton in the coil as well as coil itself.
