Stop Your Vape from Leaking: 6 Causes and Simple Solutions

A leaking vape device can turn a smooth vaping experience into a frustrating and messy situation. There are various types of leaks, such as refillable pod, sub-ohm tank, and vape kit, among others, and they are one of the most frequent issues that vapers have to deal with. Fortunately, the majority of the leaks can be prevented or repaired as soon as you are aware of the cause of the leak.

We will discuss the 6 most common causes of your vape leaking and give you clear-cut answers, so you can have a cleaner hassle free vape all the time.

Reasons Why My Vape Device Is Leaking

1. You May Not Be Filling Your Tank Properly

One of the most common causes of vape leaks is filling your tank or pod to the brim. Each device has a fill line limit, and going past it may lead to the spillage of e-liquid through airflow vents. A small air gap will aid in forming a vacuum, which will hold the liquid in position and will not allow the dripping to take place.

The other error that people make frequently is to pour the e-liquid in the central airflow channel also known as the chimney of your coil. This section is purely meant to accommodate vapour. When liquid is poured into this section, it passes through the coil and out of the bottom of your tank.

How to Fill Correctly:

Locate the fill ports next to the central airflow.
Tilt your tank at a 45° angle while filling.
Fill only up to the max line, typically just below the mouthpiece.

Pro Tip: Use a syringe or dropper for precise filling and avoid spilling liquid into the central chimney.

2. The Coil May Not Be Properly Installed

The best coils will not operate well as long as they are not installed properly. The majority of the modern coils are currently plug-and-play, though being misaligned may create openings where the e-liquid can flow. The silicone ring that surrounds the coil is part of the anti- leak system and thus it should fit snugly in the position.

For screw-in coils:

Screw it in making sure that the coil is in position, otherwise cross-threaded.

For glass tanks:

Always make sure that no components are not connected and firmly tightened, without overtightening which may cause the silicone seals to be destroyed and leak.

Remember: It is important to remember that your device has a manual where you can find instructions on how to install coils, wrong installation being the most frequent cause of a leak in a vape tank.

3. The Pod or Tank May Be Damaged

Physical damage is another frequent cause of leaks. Glass tanks can crack if dropped or overtightened, while refillable pod kits are more durable but can still sustain damage.

What to Check:

Inspect your tank or pod for cracks, chips, or stress lines.
Examine silicone seals for any wear or tearing.

Replacing a damaged pod or tank is often the fastest way to stop persistent leaks.

4. You Are Using the Wrong E-Liquid for Your Coil

The wrong e-liquid may be chosen, which can ruin the coil's performance and result in leaks. The coils are made to certain VG/PG ratios:

Direct-to-lung (DTL): Low-resistance coils (0.15-0.6ohm) are used in high-powered sub-ohm kits and they are designed with high VG e-liquids (70/30 shortfills). High PG e-liquid can become overly runny because of using thin e-liquid.

Mouth-to-lung (MTL) devices: Novice pods and vape pens operate on relatively high-resistance coils (0.71.5 Ohms) and are optimised with high PG e-liquids (50:50 freebase or nic salts). In this case, thick VG liquid will lead to accumulation and spill.

Tip: To ensure maximum coil effects and avoid leakage, always use the e-liquid that is compatible with your device.

5. The Coil May Need to Be Changed

Coils have a limited lifespan; they last 12 weeks on average. An e-liquid that is burnt or worn out cannot hold the e-liquid in place, resulting in leaks.

Signs You Need a New Coil:

Burnt taste while vaping.
Darkened or discoloured e-liquid.
The production of less vapour or strange gurgling.

A leak of a pod or a tank can be easily fixed by simply replacing the coil.

6. The Device Is Getting Too Hot

Excess heat is another common culprit. Using your coil above its recommended wattage range or “chain vaping” without breaks can overheat the e-liquid. Overheated liquid loses its viscosity and may leak through the coil.

How to Prevent:

Always check the coil's wattage range (usually printed on the coil or packaging).
Take regular breaks between vaping sessions.
Avoid chain vaping for prolonged periods.

Proper temperature management not only prevents leaks but also extends the life of your coil and device.

How to Fix a Leaking Vape Device

Remove the pod or tank from your device.
Blow gently into the mouthpiece while wrapping it in a towel to remove excess liquid from the coil chamber.
Wipe up excess e-liquid with a paper towel.
Allow the device to cool completely before refilling or vaping.
Check the coil—ensure it is fitted correctly or replace if necessary.
Refill carefully up to the maximum fill line only.

Additional Tip: Regular maintenance and cleaning of your tank or pod reduces the chance of leaks and ensures your device functions at its best.

Conclusion

The majority of the pods and tanks are leakproof. These steps will help you considerably decrease the risk of messy leakage and have a much smoother vaping experience.
