Why Is My Vape Leaking Juice In My Mouth? Vaping Mishaps Explained
Vape juice in your mouth, often called spitback or leaking, typically results from poor coil saturation or incorrect vaping technique, though it can also be caused by equipment malfunctions. Addressing these issues usually resolves the problem.
Understanding Vape Leaking and Spitback
Vaping has become a popular alternative to traditional smoking, offering a range of flavors and nicotine levels. However, experiencing leaked or spitback vape juice can be an unpleasant surprise for new and experienced vapers alike. This article breaks down the reasons behind this common issue, providing practical solutions to keep your vaping experience clean and enjoyable. We’ll cover everything from coil issues to vaping techniques and equipment maintenance.
The Mechanics of Vaping: A Quick Overview
To understand why leaks and spitback occur, it’s essential to grasp the basics of how vape devices work. A vape device essentially heats e-liquid (also known as vape juice) to create vapor, which is then inhaled. This process involves:
- Battery: Powers the device.
- Tank/Cartridge: Holds the e-liquid.
- Coil: A heating element that vaporizes the e-liquid, usually made of wire and wicking material.
- Wick: Absorbs the e-liquid and feeds it to the coil.
Common Causes of Vape Juice Leaking
Several factors can contribute to vape juice ending up in your mouth. Identifying the specific cause is the first step toward resolving the issue.
- Over-Priming the Coil: Too much e-liquid saturating the wick can lead to flooding and subsequent spitback. This often happens when initially setting up a new coil.
- Under-Powered Device: If your device isn’t set to the correct wattage for your coil, it may not vaporize the e-liquid efficiently, resulting in pooling and leaking.
- Improper Inhalation Technique: Not inhaling deeply and consistently can cause e-liquid to accumulate in the coil.
- Incorrect E-Liquid Type: Thinner e-liquids (high in PG) may leak more easily from certain tanks designed for thicker (high VG) e-liquids.
- Damaged or Worn-Out Coil: A coil past its prime may not vaporize e-liquid effectively and can leak.
- Tank Malfunctions: Damaged seals, cracks in the tank, or loose connections can lead to leakage.
- Incorrect Assembly: Over-tightening or not properly seating parts when reassembling the tank can cause leaks.
- Airflow Issues: Restricted airflow can cause pressure imbalances that lead to leaks.
Troubleshooting and Solutions
Addressing vape leaking requires a systematic approach. Here are some troubleshooting steps:
- Check Your Coil: Ensure it is properly installed, not damaged, and appropriate for your device’s wattage. Replace the coil if necessary.
- Adjust Wattage: Increase the wattage within the recommended range for your coil.
- Modify Your Inhalation Technique: Take slow, steady, and deep inhales.
- Check O-rings and Seals: Ensure they are in good condition and properly seated. Replace damaged or worn seals.
- Examine the Tank: Look for cracks or damage. If found, replace the tank.
- Prime Your Coil Correctly: When priming a new coil, only add a few drops of e-liquid directly onto the wicking material, avoiding over-saturation.
- Use the Correct E-Liquid: Select an e-liquid with a VG/PG ratio that is appropriate for your device and tank.
- Clean Your Device Regularly: Remove any accumulated e-liquid from the tank and surrounding areas.
Preventing Future Leaks
Prevention is key to avoiding future issues with leaking and spitback. Here are some preventative measures:
- Proper Maintenance: Regularly clean and maintain your vape device.
- Correct Coil Priming: Prime new coils carefully to avoid over-saturation.
- Appropriate Wattage Settings: Use the recommended wattage range for your coil.
- Quality E-Liquid: Use high-quality e-liquid from reputable brands.
- Regular Inspections: Periodically inspect your device for damage or wear.
Frequently Asked Questions (FAQs)
Why is my new coil leaking immediately after filling the tank?
A new coil leaking immediately is often due to over-priming. You’ve likely saturated the wicking material too much, and the excess liquid is seeping out before it can be vaporized. Try firing the device at a low wattage to slowly burn off the excess, or gently blow through the tank to force some juice back into the cotton.
How can I tell if my coil is flooded?
A flooded coil usually presents with gurgling sounds and weak vapor production. You might also taste raw e-liquid without the vaporizing sensation. This indicates that the coil is overwhelmed with e-liquid and cannot properly heat it.
What is the difference between PG and VG in e-liquid and how does it affect leaking?
PG (Propylene Glycol) is thinner and delivers a stronger throat hit, while VG (Vegetable Glycerin) is thicker and produces more vapor. E-liquids with a higher PG ratio are more prone to leaking, especially in tanks designed for higher VG liquids.
My vape is leaking from the airflow holes, what could be causing that?
Leaking from airflow holes often indicates excessive e-liquid in the coil chamber. This could be due to over-filling the tank, incorrect priming, or improper storage (lying the device on its side). Try cleaning the area around the airflow holes and adjusting your filling technique.
How often should I replace my coil?
Coil lifespan depends on usage and e-liquid type, but typically ranges from 1-4 weeks. Signs of a failing coil include reduced vapor production, a burnt taste, and increased leaking. Replace the coil when you experience any of these issues.
Can the way I store my vape device cause it to leak?
Yes, storing your vape device horizontally can lead to leaks. E-liquid can seep out of the tank through the coil, especially if the seals aren’t tight. Store your device upright whenever possible.
What does “priming” a coil mean and why is it important?
Priming a coil means saturating the wicking material with e-liquid before using it for the first time. This prevents the coil from burning out immediately by ensuring the wick is properly saturated before heating.
Why does my vape sometimes “spit” hot juice into my mouth?
“Spitback” occurs when e-liquid pools on the coil and then violently boils and spatters when heated. This can be due to over-priming, under-powered device settings, or using a coil with poor wicking.
Are some vape devices more prone to leaking than others?
Yes, some devices are inherently more prone to leaking due to their design. Tanks with bottom airflow are often more susceptible to leaks than those with top airflow.
I’ve tried everything, and my vape still leaks. What should I do?
If you’ve tried all troubleshooting steps and your vape still leaks, it may be a manufacturing defect or a compatibility issue between your tank and device. Consider contacting the manufacturer or retailer for assistance, or researching a different tank known for being leak-resistant.
Does the type of vape juice I use affect the coil?
Yes, sweetened e-liquids can gunk up coils faster due to the sugars caramelizing on the coil’s surface. This shortens the coil’s lifespan and can contribute to leaking. Consider using less-sweetened e-liquids to extend coil life.
Can over-tightening the tank cause leaks?
Yes, surprisingly, over-tightening the tank can actually cause leaks. It can damage the O-rings or strip the threads, creating gaps that allow e-liquid to escape. Tighten the tank just enough to create a seal, but avoid excessive force.
