WARNING

I believe that many vapers have encountered this problem: the newly purchased device starts to leak soon after use, which not only affects the user experience, but may also stain clothes and fingers. The vape leaking problem seems complicated, but in fact, there are traces in most cases. Understanding the root cause of the leakage can not only help us solve the problem in time, but also prevent it in daily use.

In this guide, let's explore why vapes leak, and use some simple methods below to help you solve the problem quickly.

Improper Vape Coil Installation: A Common Cause of Leaks

The vape coil is a vital part of your vape device. If it’s not installed properly, it’s one of the main reasons for vape leaking. When the vape coil is not fully tightened, the e-liquid will leak out of the gap. But it should be noted that over-tightening can also cause problems—it may damage the seal or thread, and increase the risk of leakage.

Fixes: The correct installation method is to tighten the vape coil by hand, and then apply light force after feeling the resistance. Avoid using tools to tighten it forcefully, which can ensure the sealing effect without damaging the vape components.

Overfilling

Many novice users think that the more e-liquid is added, the better. In fact, this is a common misunderstanding. Each vape tank has its maximum capacity limit. Overfilling can cause e-liquid to leak from the airflow holes or other parts of the vape tank.

Fixes:  When refilling e-liquid, you should leave appropriate space for the liquid to expand. It is generally recommended to control the amount of refilling to about 80-90% of the tank capacity, which can not only ensure sufficient use time, but also avoid vape leaking.

Wrong Vape Juice

Different vape devices have different requirements for the viscosity of the e-liquid. If your e-liquid is too thin — especially those with low VG (vegetable glycerin) and high PG (propylene glycol) — it may leak easily from the cotton wick of the vape coil.

Fixes: When choosing e-liquid, you should decide according to the characteristics of your own device. Generally speaking, high-power vape devices are suitable for liquid with high VG content, while low-power devices are suitable for a balanced PG/VG ratio.

Failure to Keep the Vape Tank Vertical

Gravity is an important factor that causes e-liquid leakage. When the vape is placed horizontally or inverted for a long time, the e-liquid tends to flow to the airflow holes, causing leakage. Especially in a high temperature environment, the fluidity of the e-liquid will increase, which is more likely to happen.

Fixes: In daily use, try to keep the vape vertical, especially when not in use. If you need to carry it, choose a dedicated storage box or protective cover to effectively reduce the risk of vape leaking.

Chain Vaping

Frequent and continuous vaping will cause the vape coil to overheat, which in turn affects the viscosity of the e-liquid. When the e-liquid becomes too thin, it is easy to leak out of the vape coil. In addition, chain vaping may also create too much suction pressure, drawing e-liquid into areas it shouldn't go.

Fixes: Reasonably control the frequency of vaping and allow the device to have sufficient cooling time, which can not only avoid vape leaking, but also extend the lifespan of the vape coil.

Damage to the Equipment

The seal ring, thread or other sealing parts of the vape device may age or be damaged after long-term use. These seemingly minor problems are often the root cause of vape leaking.

Fixes: Regularly checking the various components of the device and replacing aging seals or other vulnerable parts in time are effective ways to prevent vape leaking. If you find that the device itself has structural problems, it is recommended to contact after-sales service in time or consider replacing the device.

Vape Coil Needs to Be Replaced

The vape coil has a certain lifespan. When the cotton wick is aged or has too much carbon accumulation, its e-liquid absorption and retention ability will decrease, which is easy to cause e-liquid leakage. Generally speaking, the lifespan of the vape coil is about 1-2 weeks, depending on the frequency of use and the type of e-liquid.

Fixes: When you find that the vape has a bad flavor, the vapor production has decreased, or there is a burnt smell, you should consider replacing the vape coil. Regular replacement can not only prevent e-liquid leaking, but also ensure a good user experience.

Conclusion

Although e-liquid leakage is indeed a headache, in fact, most cases can be prevented. As long as you use it properly, clean the device regularly, and replace the vape coil in time, you can greatly reduce the probability of leakage. Mastering these tips will not only make you vape more safely, but also extend the life of the device and make every puff smoother.

FAQ：

Q1: Is a leaking vape dangerous?

A: Generally not dangerous, but it will stain clothes. If it leaks onto the circuit board, it may damage the vape device, and it will be a little irritating if it touches the skin. If you find leakage, wipe it clean in time.

Q2: How to prevent vape leaking?

A: Install the vape coil tightly, don't fill it too full, put it vertically, replace the sealing ring if it is broken, and don't vape it continuously.

Q3: Why does the vape juice leak into your mouth?

A: The main reason is that the vape coil is not installed properly, or the vape juice is too full. Another reason is that you vape too quickly and too hard, which creates negative pressure and sucks the vape juice up.

Q4: Does temperature affect vape leaking?

A: Yes. When it is hot or the vape device is hot, the vape juice will become thinner and leak easily. So don't leave it in the car in the sun, and don't use it continuously for too long.

Q5: What should I do if it still leaks after trying various methods?

A: It may be a problem with the vape device itself. Check if there are any cracks or aging of the sealing ring. If it doesn’t work, contact vape support for help, or consider getting a new one
