Flooding and gurgling usually arise when the coil is oversaturated with e-liquid, resulting in an excess amount of liquid within the coil. In such a situation, the amount of e-liquid is overwhelming to the coil, and the heat is incapable of vaporising all of the liquid that is present at that time. This flooding, then, results in a gurgling sound that is often accompanied by leaks and spit-back. Here are some general steps that you can take to help reduce and eliminate flooding and gurgling of your coils and tanks.
Issue 1 - Faulty Coil:
One of the most common causes of flooding and gurgling is a bad coil. Luckily, this is also the easiest problem to resolve, as simply switching out your coil could do the trick. If a coil is old and has been used for a period of time, it can lead to flooding, gurgling, and spit-back if it is not replaced. Likewise, sometimes a brand new coil can be a dud that lasts a fraction of the time you expect it to or can be faulty right from the start. Try replacing the coil to see if it helps eliminate the problem. If your coil has already been flooded, blowing air through it and drying off the excess liquid with a paper towel will help soak up the excess e-liquid.
Issue 2 - Wattage Setting:
Another widespread cause of flooding and gurgling is the output wattage your device has been set to. The resistance of your coil and the output wattage/voltage have an inverse relationship. That is, the lower the resistance, the higher the wattage should be, and vice versa. Each resistance tank will have a range that is considered the “sweet spot.” If your power output is set too low to properly heat the coil, it will result in flooding and gurgling. Try increasing your wattage/voltage to a level that is within the recommended range—this may resolve the flooding and gurgling you are experiencing.
Issue 3 - Check e-liquid Level:Each tank has a maximum e-liquid capacity. Some tanks are larger and can, therefore, hold a greater volume of juice, while others are smaller and can hold less. Regardless of the tank size, overfilling it can result in flooding, gurgling, and spit-back. As a general rule of thumb, you want to fill your tank to a level slightly below the air hole or chimney. The chimney is the portion of the tank that leads to the drip tip. You should never allow e-liquid to get inside the hole and should add enough liquid so that the level is below the chimney.
Issue 4 - Forceful Hits:
Some vapers, particularly beginners who have recently quit cigarettes, often tend to take extremely long and forceful hits. This is commonly due to the way in which the individual user to take drags from a cigarette, which tends to be rather vigorous. It can also be the result of the airflow control valve being set too tightly, which causes the user to take more powerful draws. Try taking softer hits with a slightly loosened air intake. This can greatly help reduce or eliminate flooding and gurgling.
When beginning to vape, remember to draw from the mouthpiece as you hold down the fire button (not before or after pressing the button) Take smooth 1-2 second draws, to begin with until you find the best sensation for you. Also, experiment with the airflow of the tank allowing as much air as comfortable for you to produce a smooth spit free vape.
In the event that your airflow valve is adequately loose and you still find yourself taking too forceful of drags, then your tank’s air holes may be clogged due to residue or some sort of build-up that is restricting proper airflow. In this case, disassemble the entire tank so that all of the various components are detached from one another. Then, use a small object, such as a toothpick, to clean out the various air holes, nooks, and crannies. Then, run all of the parts underwater, shake vigorously, and dry with a paper towel. Ensuring unrestricted airflow within your tank can substantially help with flooding.
Issue 5 - Excess e-liquid During Priming:
Priming a new coil is an essential step to take for your overall vaping enjoyment. A properly primed coil will result in a much richer and tastier flavour, thicker vapour clouds, and a longer-lasting head. Taking the necessary steps to prime a new coil will also help you avoid dry or burnt hits. However, if too much e-liquid is added to a new coil, this can result in flooding and gurgling. The amount of e-liquid necessary to properly prime a new coil greatly depends on the specific coil being used. A small coil, such as the Aspire BVC Coils, will require substantially less liquid than a much larger one, such as those used with the SMOK Cloud Beast Tank.
In the event that you accidentally added too much e-liquid during priming, simply remove the coil and shake it to help dispose of some of the excess liquid. Then, wrap a paper towel around the coil tightly to help absorb more of the excess juice. This should be sufficient; however, if the coil is still flooded, you may need to blow air powerfully through the coil to expel any excess e-liquid.
Issue 6 - Tank Assembly:
All tanks, irrespective of the make or model, function using vacuum pressure. In order for the vacuum effect to function appropriately, the tank needs to be well-sealed and air-tight. Check the assembly of the tank’s various components to ensure that everything is connected properly and securely. In addition, inspect the various parts for cracks or gaps that could potentially allow excess air to enter the tank. This can also contribute to flooding and gurgling.
