Why Is My Vape Tank Leaking? Here's How To Fix

Why is my vape tank leaking?

A leaking tank is one of the more frustrating things a vaper can experience. Unfortunately, there’s no 100% fool-proof method to eliminate leaks from your tank, as all tanks are different in one way or another. With some proper care, maintenance and attention, these leaks can almost be eliminated completely.

We always advise getting to know your device properly before use, through consistent use as well as reading the user manual. It’s also highly recommended to clean your tank regularly to not only maximise the lifespan but also to extract rich and clear flavour.

If you’ve got a tank which is seeping out e-liquid, fear not, we’ve got you covered. Here are some of our handy tips to avoid the embarrassment of a leaky tank:

  • Sometimes leaks can occur when a coil has simply expired and needs to be replaced. If your flavour starts to deteriorate and tastes unusually bitter, this could because of cotton degradation or holes in the wick that e-liquid can seep through.
    It’s important to change coils as soon as possible.
  • Avoid getting e-liquid in the centre tube at all costs, this is the airflow chimney and must remain clear at all times. If you’re unsure as to where the juice port is on your tank, then simply read the user manual. If you do accidentally refill your airflow chimney with e-liquid make sure you thoroughly clean off any liquid and not use your device until completely dry.
  • Coils can become loose when removing the base for refilling or cleaning so always ensure this has been tightened before use. Also, it’s necessary you thread and secure back correctly and not crooked or cross-threading which can easily create a leak.
  • As well as this, certify your coil is sitting firmly within the base unit and not overtightened. This goes for all parts of the tank, ensure everything is just hand tight, as over-tightening can break the seals, which will essentially cause leaks.
  • Always keep your tank as upright as possible when in use, stored or being transported. Leaving the tank on its side or upside down will potentially allow e-liquid to seep through the holes, including the airflow chimney and mouthpiece. If this has ever happened to you, you’ll know it’s a pain to clean up properly.
  • Check your O-rings. You can do this by taking your tank apart and analysing whether they’ve degraded or loosened. Most tanks and kits usually come with spare parts for a quick and easy replacement.
  • Ensure no e-liquid is sitting under the coil, as instead of being vaporised from the wicking material, this e-liquid will simply boil and create a gurgling sound. This can essentially flood through the airflow and leave you with a nasty mess to clean up.
  • Sometimes inhaling too forcefully on your mouthpiece can induce flooding. This is because too much e-liquid is drawn into the coil from the tank but not enough has been vaporised, leaving you with excess e-liquid filtering out of the mouthpiece and potentially the airflow once left to collect.
  • Not using your device at a high enough wattage can also cause flooding, due to the same principle of too much e-liquid not being able to be vaporised at an appropriate rate. Always check out the user manual as to what is the recommended wattage for your tank.
  • Although quite rare nowadays, if your tank has a bottom filling system, it’s good practice to close off the airholes when refilling the tank. This creates a cushion of air when the tank or device is rotated back to the upright position. As air is drawn up through the airflow, more will replace it and this maintains the cushion of air in the airflow chamber, preventing e-liquid from flowing through it.
  • Whilst this may seem obvious, it’s necessary to always use the correct e-liquid for your coils as it can create problems if not. For example, if you’re using a high PG e-liquid in a low resistance sub ohm tank, then the wicking holes will allow through the thinner e-liquid which it isn’t designed to withstand, causing flooding issues.



These are just a few ways to stop you from getting a leaky tank. If you’ve done all of this and the problem persists, unfortunately, the tank may be too far gone gone and you may need a new vape tank altogether.

Most vape tanks nowadays are constructed to protect you against these problems however, so with a little TLC, you’ll find your tank should be long-lasting and mess-free.
