Why Is Your Vape Tank Leaking And How To Stop It?

A vape tank is one of the crucial components of a vape device. The tank is a particular area within the device that holds your vape juice.


A wick (or several wicks) connects the tank to the heating chamber. When you turn on your vape device, the coils located within the heating chamber generate heat, which in turn heats the e-liquid in the tank through a wick (or wicks).


As the e-juice heats up, it produces clouds of vapor inside the tank. You then suck into your vaporizer through the mouthpiece to draw the vapor from the tank to your mouth or directly into your lungs. Evidently, the tank is an irreplaceable component of a vaporizer. Therefore, it’s essential to clean and maintain it regularly to prevent it from getting damaged.

However, cases of leaking vape tanks aren’t unheard of. But what causes these leaks, and how can you prevent them?


This post shall attempt to shed more light on that.



Why Is a Leaking Vape Tank Such a Terrible Thing?


You’ve probably read tons of articles encouraging you to close all the water taps properly before leaving your house. The same logic applies to dripping vape tanks. While it might be convenient to ignore the tiny droplets falling off your vape tank, it may only be a matter of time before the entire e-juice drains away. This means you’ll be incurring extra costs in refilling your vape tank sooner than you should.


But even if you don’t give enough thought to the financial implications, just picture the kind of embarrassment that a leaking vape tank can cause you. Imagine you’re making an important presentation then all of a sudden, you realize your crotch is all drenched up in the liquid. You’ll have to stop your presentation midway and embark on the difficult task of convincing everyone that you didn’t just empty your bladder.


So, whether you look at it from a financial or public relations point of view, a dripping tank is the last thing any vaper wants to deal with. Fortunately, there are numerous ways to handle leaking vape tanks. You just need to establish the cause of the leak so that you can adopt the right solution.

Possible Reasons Why Your Vape Tank Is Leaking and How to Fix the Problem


1. Overfilling the tank


Most vape tanks feature a central tube extending from the coil up to the mouthpiece. If you overfill the tank, you’ll most certainly get liquid in this tube, and that will cause leaks.  To avoid getting any vape liquid in the central tube, always fill the tank while tilted. That way, the vape juice runs all the way down the inside of the plastic or glass and stays away from the central tube.


As the tank fills up, you can straighten it gradually to avoid spills. If you accidentally get liquid inside the central tube, remove it before your next vaping session.


2. Loosely-screwed components


Another possible cause of a leaking vape tank is the loosely-screwed components of your vape device. In such cases, leaks will mostly occur where the coils meet with the atomizer base or where the coils meet the tank.


The easiest solution here is to screw these components tightly. And while you’re at it, avoid cross-threading (a situation where the threads of the various components you’re trying to screw together end up misaligned). Cross-threading can cause an imperfect seal.


Another thing to avoid is over-tightening the components of your vape device. Over-tightening can damage your O-rings, resulting in leaks. On the same breath, always ensure that the O-rings are properly installed and replace them as soon as they’re worn out.

3. Mismatching the resistance coils with the vape juice


Unknown to many vapers, the different resistance coils work well when matched with specific types of e-juices.


Generally, higher resistance coils produce less vapor and more throat hit. Such coils require a stronger draw, which makes them suited to e-liquids with a higher concentration of the thinner propylene glycol (PG). On the contrary, sub-ohm coils produce more vapor and less throat hit. These coils have more open airflow and present little resistance when you’re drawing, making them ideal for vaping e-juices with a higher concentration of the thicker vegetable glycerin (VG).


4. Poor use, maintenance, and storage


How you use, maintain, or store your vaporizer can also contribute to vape tank leaks. For instance, leaving your vaporizer in a horizontal or slanting position can cause the vape juice to escape from the tank through the juice holes located in the coils. Also, vaping using numerous short draws increases condensation, which in turn could cause leaks. To reduce condensation, you should consider long puffs.


It’s also advisable to inhale slowly and softly as opposed to firmly and sharply.  Other best practices for reducing vape tank leaks include;

  • Increase your power setting to prevent the amount of e-liquid from getting pulled to the coil for vaporization
  • Add extra wicking material
  • Invest in leak-resistant e-cigs
  • Replace the tank if required



Having a leaking vape tank is the surest way to lose your precious e-juice and incur additional expenses on unnecessary refills. Thankfully, there are numerous tips you can implement to address this problem. Most importantly, remember to regularly clean and maintain your vaporizer to keep all its components in crisp condition.
