Have you ever been vaping and gotten a mouthful of hot liquid? Or experienced that dreaded “pop” when you take a drag? If so, then you’ve experienced spitback and popping. 

Spitback is a common issue that vapers face, especially when using sub-ohm tanks. It occurs when e-liquid is heated and then expelled through the mouthpiece and can be quite unpleasant. There are a few reasons why this might happen, and in this article, we'll explore what causes spitback, and how you can avoid it.

What Causes Spitback?

The first reason spitback might occur is if your coil is over-saturated with e-liquid. This can happen if you prime your coil with too much e-liquid, or if you don't allow enough time for the e-liquid to soak into the wick before taking a vape. The excess e-liquid will be heated and expelled through the mouthpiece when the coil is over-saturated.

Another reason for spitback is if the airflow on your tank is set too low. This can restrict the flow of e-liquid to the coil, which can cause it to overheat and spit back.

Finally, if the coil is positioned too close to the mouthpiece, this can also cause spitback. This is because the airflow will be restricted, and the e-liquid will be drawn up into the mouthpiece. 

What Is Popping?

Just something about the gentle popping and crackling as you fire up your vape is relaxing. It's like an open fire or the sound of a burning cigarette. It's a pleasant addition to an already enjoyable moment.

Popping is a bit different than spitback, and is actually caused by your coil. When you take a drag on your e-cigarette, the air that’s being pulled through your coil creates a vacuum. This vacuum pulls the liquid from your wick, which then vaporises. 

However, if your coil is too hot, the liquid can vaporise too quickly, creating a mini explosion. This explosion causes that popping sound and can cause your coil to spitback.

How to Minimise Spitback and Popping

Now that we know what causes spitback and popping, let’s discuss how to minimise them. 

1. Prime Your Coil Properly

This is the most important step in minimising spitback and popping. You’re basically saturating your wick with liquid when you prime your coil. This allows your coil to heat up slowly, which prevents the liquid from vaporising too quickly.

2. Make Sure the Juice Is Flowing Correctly

If the juice isn't flowing correctly, it can cause spitback and popping. To ensure that the juice is flowing correctly, you need to ensure that the airflow is set correctly. If the airflow is too tight, the juice won't flow right and you'll end up with spitback and popping.

3. Adjust Your Airflow

The last thing you must do is ensure that the airflow is set correctly. If the airflow is too tight, the juice won't flow correctly and you'll end up with spitback and popping. The best way to find the right airflow is to experiment and see what works best for you.

Conclusion 

When it comes to vaping, one of the most annoying things that can happen is spitback and popping. This usually occurs when the coil isn't wicked properly, the juice must flow correctly, or the airflow needs to be set correctly. Thankfully, you can do a few things to minimise it. By following these tips, you can minimise spitback and popping when vaping.
