6 Causes of a Vape Leaking
- Heat. Warm temperatures thin the e-liquid, making it more likely to seep. Fix: store cool.
- Drawing too hard. Forceful pulls can flood the wick. Fix: draw gently and steadily.
- Storing on its side. Lying flat can let e-liquid pool. Fix: store upright.
- Air-pressure changes. Flights or altitude shifts can cause seepage. Fix: keep it upright and sealed.
- Minor damage. A knocked or dropped device may leak. Fix: handle gently.
- Condensation. Some liquid in the mouthpiece is normal; tap it out gently. Fix: clear the mouthpiece.
Most leaks are minor and preventable. A little condensation in the mouthpiece is normal and not a true leak; simply tap the device gently to clear it.
