Why is My Vape Spitting / Leaking: 12 Causes & Fixes

When you sit down to a relaxing vape and suddenly experience a hot awful-tasting liquid on your tongue, needless to say, that ruins your vaping time. Whether it is an expensive device or a pocket-friendly one, a spitting/leaking vape is a very common problem among the vaping community. 

To be fair, most modern vaping companies are coming up with leak-proof devices for all budget needs. However, lack of proper maintenance or a faulty component in the vaping device could result in a spitback ruining one’s vaping experience. 

Rivaling the spitting of a vaping device is another problem: leaking. For plenty of reasons, the pods just leak sometimes and make a mess of your clothes or bag you keep your device in. 

Both these issues occur irrespective of whether you are a newbie or an experienced vaper. 

You don’t have to worry too much though because we got solutions for most of your spitting, leaking, or popping problems. Just read on and fix your device based on the cause. 

Vape Spitting & Leaking – 12 Popular Causes & Fixes

1. Low Wattage Setting 

This is a common issue for devices that have sub-ohm vaping setup. 

When the wattage setting is too low, the coil takes a while to reach the vapor-generating temperature. When you inhale with this setting, the e-liquid will be pulled into the atomizer even before the coil gets heated up enough. 

As a result, the vaporization doesn’t happen as expected and instead, the e-liquid will be inhaled through the mouthpiece. 

Fix: This issue has a very simple fix. Just increase the wattage settings on your e-cigarette and this problem will vanish. 

If you are someone who wants cooler vapes, then instead of changing your wattage, reduce your tank’s airflow setting and let the air pressure take care of your problem as you inhale. 

If your wattage setting is already high, read on to diagnose the problem. 

2. Forceful Inhalation 

Sometimes when you forcefully inhale, you increase the airflow resulting in more e-liquid being pulled into the chambers. This will, in turn, result in your device spitting and popping. 

Fix: Take smaller inhales. Also, check the airflow settings on your device to ensure that they are not high. 

3. Flooded Atomizer

When your device is constructed with a rebuildable atomizer, you need to exercise caution while dripping the vape e-liquid. At no point must the coil be drowned in the e-liquid. 

Fix: At the cost of a decreased vapor production, you will need to ensure that the coil doesn’t drown. Drain out any excess e-liquid that may be drowning the coil. 

4. Worn-Out O-Rings

There are tiny rubber rings in a vaping device’s tank that prevent the e-juice from leaking out. When they are worn out or damaged, the liquid is bound to spill over. 

Fix: Disassemble your device, take the tank out, and replace the old O-rings with new ones. They are inexpensive and readily available on the market. 

5. Thinner e-Liquid

When thinner e-liquid is used, the large wick holes that operate at higher temperatures result in coil flooding because they reach that temperature fast, especially with sub-ohm tanks. When a coil floods, it pops and spits frequently.

Fix: Use a thicker e-liquid and this should solve your vape’s spitting. 

6. Excessive Refilling

While refilling, if you have filled the tank with your favorite e-juice up to its brim, there is a high possibility that it spills over flooding the coil and atomizer. 

Fix: Never overfill your tank. The best practice is always to refill your tank to only ¾ of its capacity and not even a little more. 

Use cotton or paper to absorb excess e-juice. This should resolve those unwanted leaks. 

7. Bad Sealing

For RTA and sub-ohm tanks, several threaded joints and o-rings keep the liquid intact in the tank. 

The same structural arrangement is also responsible for the liquid not spilling into the atomizer. When the sealing is off the mark or loosely packed, it will cause spitting and leaking. 

Fix: As part of your diagnosis on what is causing your device’s constant leaking and spitting, you need to disassemble the device, clean it, seal it back up tightly, and reassemble it. 

Try vaping now and that problem should have been resolved. If not, continue reading for the other possible causes. 

8. Twisted Coils 

If your device uses twisted or braided coils, it is bound to leak once in a while as these coils are known to withhold some e-liquid in them. 

Fix: If you are making your own coil, just ensure that you braid and twist it tightly. If possible, avoid these kinds of coils as they infamously cause atomizer flooding.  

9. Narrow Drip Tips

When you inhale from a narrow mouthpiece, some vapor gets left behind and doesn’t go past your lips. These tiny bits of vapor get accumulated in the drip tip and when they get excessive, cause the popping or spitting of your device. 

Fix: Just switch to a wide bore drip tip or an RTA. Majority of RTA devices come with a wide drip tip, thus eliminating this problem of stagnation in the narrow tip.   

10. Improper Priming 

While priming the device’s coil by adding e-liquid to it before a vaping session will significantly improve the vaping quality, it will mess up the entire experience if it’s not done right. 

Once you inhale, any excess e-liquid on the coil will lead to spitting and that terrible taste is going to ruin your session even before it starts.

Fix: Figure out how much e-liquid is required to prime your vape coil. While some coils need a few drops, others will need a little more. 

So, figure out exactly how much and prime the coil accordingly. Remove any excess liquid from the coil by disassembling it again and absorbing the residual liquid with the help of a paper towel or some cotton. 

11. Defective Coil

Despite fixing everything else, the problem may persist. That signals a defective coil and there is not much anyone can do about it. 

Fix: Replace your coil with a new one. Avoid braided or twisted coils. 

12. Cracked Tank

Tanks are the strongest components in a vaping system but they are not damage-proof. Considering the heavy usage they endure, they are prone to cracks and chipping. 

So, you should take a good look at your tank if none of the above solutions seemed to fix your problem. 

Fix: Disassemble your device, open the tank, and carefully check the glass or quartz structure under a bright light. The light makes it easy for you to see any unfortunate hairline cracks or chips on the edges. 

If there are indeed cracks and if your device’s warranty allows for a replacement, change it right away before it worsens. 

If not, there are surely plenty of tanks suitable for your device that are available on the market. Replace the broken one with a brand new and enjoy your vaping. 

Conclusion

Spitting, leaking, and popping are very common problems in a vaping device. No need to worry though since most of the time, every problem can be resolved with a simple fix that wouldn’t even take five minutes of your time. 

So, instead of discarding the device that bothers you, spend some time, diagnose its problem, and let this troubleshooting article help you. Trust me—the vaping experience, after fixing your device all by yourself, is bound to be more satisfying.
