7 ways to stop your tank leaking

How to stop a leaking vape tank


If you’ve noticed that your vape tank is leaking, don’t panic. You don’t need to purchase another one (just yet), the one you have isn’t broken (probably).


Leaking is more common than you might think, and whilst it’s not the most pleasant of experiences to have e-liquid leaking from your vape tank whilst you’re vaping, it isn’t going to prevent you from doing it.


Fixing a leaking vape tank is really quite simple because 9 times out of 10, the fault lies with the user - something you’re not doing, rather than with the equipment itself.


So let’s run through 7 possible reasons why you have a leaky vape tank, and help stop your vape tank from leaking again.

1. The coils.

First off, make sure that you’re using the specific coils that fit your vaping device. If you aren’t sure, go back to the manufacturer and check that the ones you’re using are the ones that they recommend.


Remember that coils aren’t designed to last forever, so like most things, at some point, they’ll need to be replaced (usually once a week or at least twice a month), in which case, switch out the old one for a new one. If you’ve not replaced the coil for a while, or you can’t remember when it was last replaced, chances are this is the problem.  


With so many coils being manufactured each day, sometimes manufacturers manufacture dud coils. To check and see if this is the case for you and causing your leaky vape tank, replace your current coil with a new one and see if the problem is resolved. Coils are pretty cheap to replace, so look here first.

2. Clean your equipment

You don’t like it when you’re not clean, your vape tank doesn’t like it when it’s not clean. If you want your vaping device to work smoothly, you have to ensure that you clean it from time to time. Not only will cleaning your equipment enhance your vaping experience, but it will prolong the life of your equipment and prevent build up in your vape tank.


If there is build up in your vape tank, odds are, this is the cause of your leak. If this is the case, clean out the tank and ensure going forward that you routinely clean it to prevent build-up from happening again. If you stay on top of the cleaning of your vape tank, your equipment will work as well as it did the first time you used it.


Take your tank apart and rinse it out. Every week or so, or when you replace the coils, give the tank a thorough clean down and soak it in alcohol to remove any e-liquid build-up.

3. Don’t overload your vape tank

Vape tanks have a maximum fill level, so if you’re filling your vape tank above the maximum level it is designed to hold, it will leak, both out of the air holes and through the top fill hole. Always keep an eye on the maximum fill line and don’t overfill.

4. Experiment with how you hold your e-cig

Some e-cigs aren’t designed to be smoked whilst being held like a regular cigarette, i.e. horizontally. By holding your e-cig in this way, could be the reason for the vape tank leaking, because some tanks have air holes in the top of them (when you tip your device the wrong way, e-liquid can leak out), and some just don’t have robust enough seals that can withstand being smoked at a horizontal angle.


If you think your tank is leaking when you smoke it, try holding it vertically.

5. Check how you’re sealing your device

Are you screwing your tank back into your device firmly enough? Have you screwed the coil back into the tank properly? Do the threads marry up or are you screwing it in partially, leaving space for e-liquid to leak out? Check all of the seals to make sure you aren’t doing sealing your device wrongly.

6. Is the tank cracked?

Although most tanks are made from pyrex glass and are able to withstand the rigours of everyday life, sometimes tanks have weaknesses and can crack, leading to e-liquid leakage.


Sometimes that crack can be a hairline crack, so thin, you wouldn’t normally notice it. Take your tank out and inspect it close up. If your vape tank has cracked, you’ll need to replace it.

7. Check the ratio of PG:VG in your e-liquid

If your e-liquid of choice has a higher propylene glycol ratio to vegetable glycerin, this will mean that the e-liquid will be thinner, and therefore more prone to leak. If this doesn’t bother you, not a problem, but if it does, consider swapping to an e-liquid with a higher VG level, making it more viscous.

Finally, if the leaking is really bad, consider upgrading your vape tank. We have a wide selection for you to choose from.
