Since you quit smoking, between you and your vaper, it’s been a real romance. As you are inseparable, you put it in your pocket or your bag to always have it with you.

And one day, it’s the drama. When you take it out, you realize that it has severe leaks. Your e-liquid has decided to play Prison Break and you find yourself with sticky fingers and a beautiful stain which, if it will come off easily, is still quite embarrassing.

And this isn’t the first time your vaper has played this trick on you. You have so far tolerated his little antics, but this is too much! It is time for this to stop.

But here it is: finding what is causing your atomizer or clearomizer to leak can sometimes seem like a real detective story because there are many potential culprits.

That’s why I have decided to come to your rescue! Thanks to my many years of experience in the vape, I will investigate your side and, together, we will put your vaping back on the right track. So, take your little notebook and your magnifying glass, my dear Watson, here we go to solve this enigma.


In the majority of cases of leakage, the liquid flows through the airflow, but this is only the accomplice of the mischief. The guilty? No, it’s not Colonel Mustard, but your resistance.


Let’s proceed methodically. The most obvious question to ask, and yet the one we don’t often think about, is whether the resistance model you have chosen corresponds to your clearomizer. If it is not suitable, it will not be able to function properly, and this will cause leaks.

To verify that you have made the right choice or if you want to be sure when restocking, simply enter the name of your clearomizer on the A&L site, and we will find for you all  the resistors compatible with the model . in your possession.

Once you are sure you have made the right choice, comes the question of assembly: is your resistance tight enough? If this is not the case, the play between the resistance and the base will allow the e-liquid to pass, and you will end up with damage.

Whether this is due to inattention during assembly or because transport and handling have loosened it, this little problem is easily adjustable: completely empty your tank (if it didn’t take care of it on its own), unscrew the tank from the base, and tighten everything. To avoid getting your fingers dirty and especially slipping, you can use pliers or a paper towel, this will give you more grip to tighten the resistance.

It still isn’t it? So it’s time to take a look at his condition. If it is too worn, the resistance will no longer be able to fully vaporize the e-liquid, the surplus will therefore escape through the airflow.

Normally, a resistance that needs to be changed is recognized when vaping: in addition to leaks, you will notice that the flavors are more bland, even tinged with a burnt taste. If you have any doubts, you can also dismantle it: when it needs to be changed, cotton and threads turn black.


Fans of reconstructable know it: making a perfect assembly requires a lot of skill, and sometimes there are misses.

If since you made your last resistance your ato does not stop leaking, it is certainly because there is not enough cotton. The capillarity is then insufficient, and the e-liquid has free rein to go for a walk on the side of the air inlets.

By the way, also check that your resistance is screwed enough. As for the clearomizers, on some models a badly screwed resistance can leave room for the liquid to pass.

If you still have a little trouble making the resistors of your rebuildable, don’t hesitate to see this tutorial which will explain  how to make your cotton fabric like a great master. Each atomizer has its specificities, it can also be useful to see a tutorial which will explain to you precisely what you must pay attention to when making your coils.

Whether you use an atomizer or a clearomizer, maintaining your coils well can not only allow you to avoid this kind of problem, but also to keep them longer. So I have prepared a short article for you that brings together all my tips to make your coils last as long as possible!

A parts problem

The culprit is hiding well. But as strong as he is, he will not escape my famous flair!

Whether you are on an atomizer or a clearomizer, leaks can come from a problem with the different parts. You will therefore have to disassemble everything and do a major cleaning. Take the opportunity to check everything: is your pyrex damaged? A shock or a slightly aggressive liquid can compromise its integrity, so remember to bring a  vape band to protect your glasses and check that your tank is compatible with the liquid you are using.

Are your seals in good condition? Over time, the seals may deteriorate and become porous or cut, which will inevitably lead to your tank leaking. That’s not a problem: manufacturers always provide spare gaskets, so you just need to replace them. On the other hand, if it is the joints of the resistance that are damaged or missing, you will have to change it!

It could also be that you simply… forgot parts! This may be sealed but also, on some rebuildables, the part that obstructs the airflow. For example, if you mount a single coil on an auto which is also compatible in double coil, it is sometimes necessary to obstruct the second airflow with a part, also called a chamber reducer, which prevents the e-liquid from escaping. where there is no cotton to absorb it.

Let’s see so far, all the suspects have been proven innocent…but maybe that’s because the culprit was right in front of me all along! Yes, sometimes leaks are due to improper use or handling on your part. So don’t look outraged, there’s no point in denying it anymore. Go hop, in the direction of the prison! 

Atomizers, and sometimes clearomizers, have a filling limit to respect. You will find it in the user manual or directly indicated in the tank. By filling them too much, you have drowned the resistance, and what it could not vaporize flows through the airflows.

Your way of filling your auto or your clearo can also be in question. For models that fill from the top and have an airflow at the bottom, the air is compressed in the atomization chamber when filling. The only place through which it can escape is the air inlets, and it will carry the liquid by depression.

To avoid this phenomenon, even before starting the filling you will have to close the air inlets. Once done, fill, close the hatch, then turn it over, and upside down, reopen the air inlets. Then all you have to do is vape!

In any case, it is best to check the user manual for the procedure to follow when filling: some models require, for example, to be filled horizontally.

Since we are talking about e-liquid, let’s take a look at its composition: it may not be suitable for your resistance. Those with large entrances (often those intended to make large clouds) need a very thick liquid, that is to say with a higher proportion of vegetable glycerin (VG) than propylene glycol (VG). Otherwise, they pass too easily through the cotton, and that’s the leak.

Another possibility is that the vaping power you have chosen is not suitable for your resistance, which prevents it from vaporizing all the liquid… and you know the rest. To find the power at which to use a resistor, you can look directly at it: generally, the manufacturer indicates it. Another solution is to use (if possible) your box in a mode that will automatically set the ideal power.

Finally, your clearomiser may be unsuitable for your way of vaping. If you use a clearo in MTL while it is designed for a draw in DTL (and vice versa), you drown once again the resistance.

A defective resistance, missing parts, or improper use of its equipment, the causes of an e-liquid leak can be numerous. Of course, when this happens, you can deal with the problem quickly by simply wiping up the leaked e-liquid.

But once you get home and you have a little more time, you will have to work to find the origin of the problem because, be sure of one thing: a leak will not disappear by itself. . On the contrary, there is a good chance that it will get worse and worse!
