Why is My Vape Leaking? 5 Causes and Quick Fixes

Ever had a leaky vape? Then you’ll be familiar with the following scenario. It’s the first day at your new job. You confidently stroll through the office in that new suit, giving off an air of success. 

But something’s not quite right. Your new associates seem to be either smirking or awkwardly avoiding your gaze. You rush to the bathroom to gather your senses, and then you see it the unsightly wet patch on your trousers. The curse of the leaky vape!

Don’t worry, most of us have experienced it at some point or another and there are many ways to avoid this sticky situation!

Our top 5 ways to fix a leaky vape are: 

  1. Make sure you’re filling your vape tank correctly 
  2. Check your vape tank is properly tightened
  3. Try replacing your vape coil or pod
  4. Make sure your voltage/wattage are at the correct levels
  5. Check your tank to ensure it’s free of damage 

You Are Overfilling Your Tank

By far, the most common reason for a leaky vape is failing to fill the tank properly. Rule 101: never overfill the tank, and always check the manual for how to fill your tank properly.

How to Fix

There should always be a pocket of air at the top to create a vacuum. This will prevent the e-liquid from leaking out of the tank’s airflow holes.

If you have a tank that fills from the top, make sure you avoid pouring liquid down the hollow tube that runs through the centre of the tank. This is called the chimney and is definitely not for e-liquid! It will just exit your vape pen out of the bottom and create a big mess. Be careful during this procedure, and make sure you’ve followed all the necessary steps.

You Haven’t Screwed Your Tank Tight Enough

This should be your second port of call when assessing why your vape is leaking. If you haven’t screwed your tank on tight enough, the e-liquid will seep out of the joins. 

How to Fix

Make sure the top and base of the tank are screwed tightly. But not too much! If you screw them too tightly, it could lead to cross-threading, and you might not be able to take it apart again. 

Also, it might not just be the tank that needs careful attention. Ensure that your atomizer is screwed in all the way and push-fit coils are pushed all the way in. An unfitted coil will mean there won’t be a seal, and most likely cause a leak.

You Are Using an Old Coil

One of the other reasons your vape might be leaking is because your coil is old. Often, before the dreaded dry hit even occurs, there could be other signs that your vape coil is ready to pack it in.

How to Fix  

If you haven’t replaced it in a while and your tank is leaking, you should probably try this first of all. Coils will need replacing every so often (depending on the type of coil you have), we cover this in more detail in our guide to when to change your vape coils

You Have the Wrong Voltage/Wattage

Yes, I know all the information on watts, volts and ohms can be daunting but, for most of our purposes, it’s really more simple than it seems. If you have a vape pen with the capacity to adjust the voltage, it’s important to ensure your power is set to the optimum range of the coil you have inserted.

How to Fix

Firstly, check your atomiser. It most likely has the optimal range printed on it, so your best bet is to opt for somewhere in the middle. For instance, if it says 5W-15W, go for around 10. 

If you put the setting too high, you could end up burning your wick and shortening the life span of your coil. Conversely, if you end up setting the power too low for your coil, there won’t be enough power to produce vapour. 

This means you will draw too hard, which can force vape juice to leak from the bottom of your tank. Remember, moderation is key!

Your Vape Tank is Damaged

Perhaps rarest of likelihoods, though it can happen. And for those of us prone to dropping our vape pens, it may have happened more than we’d like to admit! 

How to Fix

Check if there are any cracks in the plastic or glass casing of your tank. Sometimes, a small one is all it takes for a leak to occur, so look carefully.

Additionally, when you remove the bottom or top of your vape tank, you’ll see small rubber seals. These are called o-rings. They prevent leakages between your tank’s components. 

If you see these that are broken or worn down, they won’t be sealing properly and may need to be replaced. 

Need More Help

Hopefully these recommendations will enable your vaping to proceed smoothly. One final tip: Don’t lay your vape-pen on its side! I know it seems obvious, but many of us fall prey to it now and again. Remember, nearly all vape pens have a flat base for a reason, so let them stand tall and proud and avoid those leaks!
