Leaking vapes are a nuisance. Sticky and inconvenient, and that nice e-liquid you just bought that you can't get enough of? Wasted.
Over the years, Vaporesso has built a reputation as a trusted brand, known for producing high-quality vaping devices. Yet, even the most meticulously designed vape kits aren’t immune to occasional leaks.
Thankfully, the majority of these leaks stem from easily resolvable issues, rather than inherent defects in the device itself. In this guide, we'll delve into the most common culprits behind leaks, offering practical solutions and preventative measures to keep your vaping experience smooth and mess-free.
Let's take a closer look at some of the most frequent causes of leaks in Vaporesso devices.
In most cases, leaks in Vaporesso devices result from an improperly installed coil. Common issues such as cross-threading, insufficient tightening, or misalignment can all prevent a proper seal, allowing e-liquid to escape. To fix this, carefully align the coil with the threads and gently tighten it until snug, avoiding excessive force. Remember to always prime the coil by applying a few drops of e-liquid to the cotton after installation.
It may sound obvious, but be sure to always use genuine Vaporesso coils designed specifically for your device model. These coils are manufactured to precise specifications, ensuring optimal fit and performance, whereas third-party coils often lead to compatibility issues, increasing the likelihood of leaks.
Beyond issues with coil installation, another frequent (but easily remedied) cause of leaks is an improperly attached mouthpiece, often occurring after refilling the pod. When the mouthpiece is loose, your inhale can create a vacuum that pulls e-liquid into the coil chamber, leading to flooding and leaks.
To prevent this, ensure the mouthpiece clicks firmly into place after refilling. You should hear and feel a distinct 'click' when it's correctly seated, and you can gently tug on the mouthpiece to confirm it's secure before vaping.
Another frequent cause of leaks in Vaporesso devices is overfilling the tank or pod. This tends to happen when the tank or pod is filled beyond its intended capacity, disrupting the internal pressure balance that keeps e-liquid contained.
To prevent this, always leave a small air gap at the top when refilling. Fortunately, most Vaporesso tanks and pods feature a visible maximum fill line to make this easier.
It's also crucial to avoid pouring e-liquid directly into the central airflow tube. This channel is designed solely for air circulation, and any liquid entering it will inevitably leak out.
After refilling, take a moment to wipe away any e-liquid that may have spilled onto the tank's exterior or around the coil base. This simple step can prevent seepage into unwanted areas.
Finally, keep in mind that some Vaporesso tanks and pods are designed for upright filling, while others require filling on their side. Always refer to your device's manual for the correct method.
E-liquid viscosity, determined by VG/PG ratio, is key to preventing leaks and ensuring optimal performance within your Vaporesso device. Thin, high-PG e-liquids often leak in sub-ohm tanks designed for thicker, high-VG liquids due to their larger wicking ports. Conversely, very high-VG liquid in pod systems with smaller ports can cause dry hits as it's too thick to saturate coils quickly.
To avoid issues, check your device's coil compatibility and follow the recommended VG/PG ratio. Generally speaking, Vaporesso MTL pod kits work best with 50VG/50PG e-liquids like nic salts and freebase juice, while DL sub-ohm kits suit 70VG/30PG or higher VG ratios.
O-rings are vital seals in your Vaporesso device, ensuring airtight connections between the tank's various parts and preventing leaks, but over time, e-liquid, heat, and general wear can degrade them, compromising their sealing ability.
With this in mind, it’s important to regularly inspect the O-rings for any signs of visible wear, such as cracks, tears, flattening, or discolouration, being sure to replace any damaged ones immediately. As you may expect, using the wrong size will also lead to leaks.
Environmental changes, such as altitude shifts, air travel, and extreme temperatures can significantly affect e-liquid in your Vaporesso device, causing expansion or contraction, potentially forcing liquid through airflow vents.
Reduced cabin pressure during flights is a common culprit for leaks, particularly with a full tank. Similarly, leaving your vape in direct sunlight or hot environments thins the e-liquid, increasing the risk of your device leaking.
To prevent these issues, three main pieces of advice: empty your tank before flying, avoid leaving your vape in the heat, and store it upright to prevent gravity-induced leaks through the coil and airflow holes.
While the adjustable airflow present on many Vaporesso devices enhances the vaping experience, improper use of these settings can inadvertently contribute to leaks. Specifically, if the airflow is excessively restricted during inhalation, it can create excessive pressure within the tank, forcing e-liquid out through the coil and airflow channels.
To prevent this, avoid taking very forceful inhales with the device’s airflow at its most restricted setting, as this can create excessive vacuum pressure within the tank. Additionally, regularly check the airflow channels for obstructions like debris or e-liquid buildup, as blocked airflow will require you to draw harder, further increasing the vacuum pressure and consequently, the chance of leaks.
A less frequent, but equally significant cause of leaks in Vaporesso devices is damage to the tank's components, particularly cracks in the glass or plastic. Even hairline fractures can create pathways for e-liquid to slowly seep out over time. These cracks can arise from accidental drops, impacts, or just general wear and tear.
Needless to say, regularly inspect your tank for any signs of damage and replace any cracked or faulty components as soon as possible to prevent leaks.
Leaking can be frustrating, but as we’ve explored, in most cases, it’s an easy problem to fix. By understanding common causes like incorrect coil installation, overfilling, or using the wrong e-liquid, you can prevent leaks and enjoy a smoother vaping experience.
Remember, proper maintenance and careful handling are your best defenses against leaks. If, after implementing these solutions, you continue to experience leaks, it's advisable to consider replacing your tank.
