Resolving Leaks and Spitback: Tips for a Smooth Vaping Experience

8th Sep 2023

Are you tired of experiencing leaks and spitback while indulging in your favorite vaping sessions? Don't worry, you're not alone! Leaks and spitback can be frustrating, leading to a less enjoyable vaping experience. But fear not, we're here to help you resolve these issues and enhance your vaping pleasure. In this article, we'll provide you with practical tips and tricks to tackle leaks and spitback like a seasoned vaper. Let's dive in!

Understanding Leaks

Leaky vape tanks can be a common nuisance, resulting in juice wastage and sticky devices. Understanding the causes behind leaks can help you better address the issue:

Faulty O-rings

The O-rings, located around the tank and coil, act as seals to prevent leaks. Over time, O-rings may wear out or become misaligned, leading to leaks.

Filling techniques

Improper filling techniques can disrupt the delicate balance within the tank, causing leaks. Avoid overfilling the tank, as it can impede proper airflow.

Coil issues

A faulty or worn-out coil can contribute to leaks. If the coil doesn't fit securely or if there are gaps, juice can seep through and lead to leakage.


Tips to Combat Leaks

Now that we've identified the potential causes of leaks, let's explore some effective solutions to overcome this annoyance:

Check and Replace O-rings

Inspect the O-rings on your tank and coil regularly. If you notice any signs of damage or misalignment, replace them promptly. You can find replacement O-rings at your local vape shop or online.

Master Filling Techniques

To prevent leaks caused by improper filling:

- Close the airflow holes or adjust the tank to a closed position before refilling.

- Fill your tank slowly, avoiding overfilling. Leave some space for the e-liquid to expand.

Prime Coils Properly

Ensure your coils are adequately primed before use. Prime a new coil by applying a few drops of e-liquid directly onto the exposed cotton wicking material. Allow the coil to sit for a few minutes before vaping. Properly primed coils can prevent leaks and improve overall flavor.

Check Coil Installation

Ensure the coil is correctly installed, fitting snugly within the tank. Tighten it firmly but avoid overtightening, as it may cause damage and lead to leaks. A properly installed coil will provide a secure seal and prevent e-liquid from seeping out.

Maintain Correct Wattage

Inappropriate wattage settings can cause leaks or spitback. Ensure your device is set to the recommended wattage range for the specific coil you're using. Deviating from the recommended wattage can lead to overheating, resulting in leaks and unpleasant spitback.

Understanding Spitback

Spitback occurs when droplets of hot e-liquid are ejected from the mouthpiece, often accompanied by a popping sound. It can be an uncomfortable and unpleasant experience while vaping. Let's take a closer look at why spitback occurs:

Coil flooding

When the coil is flooded with e-liquid, excess juice can accumulate, leading to spitback. Flooding can occur due to overfilling, improper priming, or excessive power to the coil.

Inadequate airflow

Insufficient airflow can cause the e-liquid to vaporize unevenly, resulting in spitback.

Tips to Combat Spitback

To prevent spitback and enjoy a smoother vaping experience, try these helpful tips:

Adjust Wattage

Experiment with adjusting the wattage setting on your device. Lowering the wattage can help reduce excess vapor production, minimizing the chances of spitback. Find the optimal wattage that provides a satisfying vape without causing excessive flooding.

Proper Airflow Management

Ensure your device's airflow is open to its desired setting. Inadequate airflow can contribute to spitback. By allowing proper airflow, you promote even and efficient vaporization, minimizing the likelihood of spitback.

Clean Your Device Regularly

Regular cleaning helps prevent clogs that can lead to spitback. Disassemble your device and clean the atomizer, mouthpiece, and tank thoroughly. Remove any excess e-liquid or debris that may have accumulated, ensuring unobstructed airflow.

Avoid Overfilling

Overfilling your tank can cause excessive flooding, leading to an increased chance of spitback. Fill your tank to the recommended level, leaving some room for the e-liquid to expand. This helps prevent excessive juice accumulation in the coil and reduces the risk of spitback.



Why is my tank still leaking after trying these solutions?

If you've followed the tips mentioned above and are still experiencing leaks, there may be an issue with your tank itself. Consider replacing the tank or seeking assistance from a professional vape technician.

Can't I just blow into the mouthpiece to clear out excess e-liquid?

While blowing into the mouthpiece can temporarily alleviate some spitback, it doesn't address the root cause. Continuous spitback indicates an underlying problem that should be resolved to ensure a pleasant vaping experience.


Resolving leaks and spitback is essential for a smooth and enjoyable vaping experience. By understanding the causes behind leaks and spitback and utilizing the tips provided, you can troubleshoot these issues effectively. Remember to check and replace O-rings, master filling techniques, prime coils properly, and maintain the correct wattage. Similarly, adjust the wattage, manage airflow, and clean your device regularly to combat spitback. Enjoy your vaping journey with confidence, free from leaks and unwanted e-liquid surprises!
