The most common problem you experience when vaping is leakage and spitback. Leakage is a completely normal part of vaping, but it does not have to be. If maintained and taken care of your vape will function optimally. Remeber to change your coils in time, set the right current, the right temperature, and use the right liquid (e-juice).
What is spittback?
There is a difference between leaking and spitting, it is important to know what vape spitting is and how you can avoid it.
Excess e-liquid coming out through the mouthpiece and into your mouth is known as vape spitting (spittback). Spitback is recognizable by e-liquid coming directly in to your mouth when you take a drag. Both the nicotine and the artificial flavors leave a strong taste in your mouth. If you vape at a high wattage, the warm liquid may make you feel uncomfortable and even burn your toung.
Oversaturation of the coil and flooding will cause spittback. While firing the device, the vapor comes up through the flooded coil head. It makes the e-juice spit up the chimney through the drip tip. The spitback e-liquid is still hot and the sensation is not plesant.
What are the reasons for leaking and vape spitting?
The difference between spitting and leaking is clear. So, what are the reasons behind leaking and spitting? The current section discusses the reasons.
Leakage can happen for different reasons. However, a vaper must know that the wrong vape tank assembment can cause leakage as well. Malfunction or manufacturer’s defect can also be a reason behind the spitting. Often, leakage comes out from the airflow inlets.
Positioning the coil incorrectly can also cause leakage. O-rings seal the tank and forbid the liquid from coming out. Thus, missing O-rings can cause leakage as well.
Spitting often makes a popping sound. Spitting happens mainly because of oversaturation or coil flooding. In the process of heating, if the small liquid droplets fall on the coil, it can shoot in different directions. Vapers will only feel the spit once it shoots through the mouthpiece.
Fill the tank correctly
The biggest reason for a leakage is the way you fill the tank. Tanks have a tube that extends from the coil up to the nozzle. If e-juice ends up in it, it is guaranteed that you experience both spitting and gurgling from your vape.
Fixing this problem is simple
When you fill e-juice in the tank, it is best to keep it at a slightly tilted angle, as you should do with a bottle of champagne when you fill it in the glass, then you avoid vacuum. The e-juice is then filled up by the sides, and far away from the center of the tank where the mentioned pipe is located. When you fill up the tank, slowly bring the tank back to a standing position as it fills up. If you are unlucky enough to get e-juice into the tube, then you must make sure that this is cleaned away before you start using the vape. You do this easily by blowing from the other end or by using a small piece of paper that you push into the tube.
Do not fill the tank completely, but leave it a little so that the vacuum can hold your e-juice in place. Feel free to turn the tank quickly upside down once, then you get the vacuum to prevent any leakage.
Keep the airflow closed while filling
While filling the tank, it is important that to keep the airflow closed fully. However, while one is using the tank, they must ensure to open the airflow enough. Taking strong hit from your vape often leads to leakage. While taking a strong inhale, there is a possibility of too much e-liquid coming into the coil. Such incidents increase the chance of leakage and spillage.
Use the right e-juice
The coil heads or sub-ohm tanks requiring too much power need an e-liquid that has over 70% VG and PG ratio. Otherwise there can be a chance of leakage because of the thinner viscosity of the liquid. If you use devices drawing huge power, it is better to use liquids with over 70% VG at least. Anything less can lead to leakage. However, if using an MTL device, anything up to 70% VG is well enough. Check the VG/PG ratio on the bottle prior to use. However, with DIY liquid, monitor the VG PG ratio.
Watch out for the cracks
Damaged tanks are rare, but not impossible. Therefore, check the tank before filling it. A thin crack on the glass or a piece of bent metal means the tank is no longer airtight, allowing the juice to leak out and flood the air hole valve. Buy a replacement tank when spotting a crack. Most of the tanks are inexpensive, so it will not break the bank entirely. Afterall vaping is all about satisfaction.
Screw everything together, correctly and carefully
Another common reason for leakage is that you do not screw everything on correctly and get gaps. Be careful when screwing together, but do not screw it together too hard. If you screw it too hard, you put pressure on the o-rings, which in turn causes the tank to expand by the pressure applied when it is full, and you will get leaks.
When not using the vape, it should stand up vertically. This has less to say if the tank is full, but has a lot to say if it is less than half full. This is because there are juice holes in the coil. This means that when the tank is full, the juice will always “fill” these gaps, but with a half-full tank, e-juice will either pass through these and into your air intake.
The right coil for the right juice
The size of the holes on the coil determines whether your vape should have an e-juice with more or less VG. A vape uses different coils. Coils with greater resistance (above 1 ohm) often have smaller juice holes in the coil and should therefore be combined with a juice that has a higher PG content. Juice with a high VG content will condense a vape with greater resistance and give you problems with operating it properly. It will simply get stuck. High VG will also require higher temperature to evaporate. So if you run your steamer at too low temperature, all the juice will be drawn through the tank and into your air intake, and finally up into your mouth. Coilers with low ohms (so called sub ohms, below 1 ohms) should have thicker e-juice with a higher percentage of VG. This is because the juice holes in a low ohm coil are larger and the air intake is larger. If you try to use a juice with a high PG content in these steamers, you will find that the juice simply flows right through the tank and into the air intake.
As previously mentioned, do not screw the tank too hard, as it puts pressure on your o-rings. Note that this is not the only thing that can affect these rings. They may also be out of position, worn, or simply have a manufacturing defect. To check these, take the tank apart and look under the top and bottom of the base. You will easily see if an o-ring is worn or out of position. Most tanks have extra rings included, but if you do not have this, we at iSmokeking.se can help with this.
Inhale slowly and calmly, not hard and intensely
If you are still experiencing leakage, there is a good chance that you are not inhaling properly. There is one fundamental difference between vaping and cigarettes in terms of inhaling: If you inhale hard on a cigarette, you will have a greater effect, while on an e-cigarette you will experience that this has nothing to do with it. If you inhale too hard on an e-cigarette, you may end up pulling the e-juice to the coil faster than the coil can evaporate the e-juice. Then you pull the juice out of the tank like a straw and will experience “spitting” and leakage from your vape.
The solution to this problem is simple. Inhale longer, calmer and think a little less about getting big clouds. Vape will come out whether you go fast and hard or light and soft. With the latter technique you will avoid many problems, get better taste and you will not go out of breath.
There is one type of leakage you do not get away from, and that is condensation When you take a draft from your vape, not all the juice is vaporized, and some will end up in the pipe and sink down towards the coil. allthough it is not much, over time it will become more and more. To minimize this, we recommend you to inhale immediately when firing, do not fire without inhaling.
