  • Overpowering the coil with a high-powered battery or excessive wattage

5 best ways to fix vape leaking

By implementing the following tips, you can tackle vape leakage and enjoy a more seamless vaping experience. Remember to assess your device’s needs and consult manufacturer guidelines for compatibility before making any changes or upgrades.

1. Double-check the coil seating: 

Sometimes, a misaligned or improperly seated coil can cause leakage. Ensure that the coil is securely and snugly positioned within the tank. Adjust or reinstall the coil if necessary to create a proper seal.

2. Upgrade to a top-fill tank: 

Consider upgrading to a top-fill tank if you’re experiencing frequent leakage. Top-fill tanks have a convenient refill mechanism that minimizes the chances of spillage and leakage during the filling process.

3. Use a thicker e-liquid: 

Switching to a thicker e-liquid with a higher vegetable glycerin (VG) ratio can help reduce vape leakage. Thicker e-liquids have better viscosity and are less prone to seeping through small gaps or airflow channels.

4. Clean the threading and connections: 

Over time, residue and gunk can accumulate on the threading and connections of your vape device, compromising the seal and causing leaks. Regularly clean these areas with a soft cloth or cotton swab dipped in isopropyl alcohol to maintain a tight seal.

5. Try a different wicking material: 

Experimenting with different wicking materials can help address leakage issues if you’re using a rebuildable atomizer. Some materials, such as cotton bacon or rayon, have better absorbency and can minimize the likelihood of flooding and subsequent leaks.

Is it normal for your vape to leak?

No, it is not considered normal for a vape to leak. While occasional leaks may happen, persistent or frequent leaks indicate an issue with the device. Leaking can occur for various reasons, including user error, improper assembly, or device malfunction. Overfilling the vape tank, not tightening the components properly, or using a worn-out coil are common causes of leaks. 

Additionally, extreme temperature or altitude changes and using e-liquids with inconsistent viscosity can also contribute to leaks. It is important to address the issue promptly by troubleshooting and taking appropriate measures such as following manufacturer instructions, checking assembly, replacing coils, monitoring temperature, and using compatible e-liquids. If the problem persists, seeking assistance from the manufacturer or a reputable vape shop is recommended.
