Troubleshooting Tips for Leaking Vape Tanks and Clearomizers

Most experienced vapers have dealt with the all too common problem of leaking tanks at least once. There’s nothing more frustrating than being out of the house when your leaking vape tanktank decides to start leaking. Without access to a paper towel, you’re stuck in a leaky mess. Irrespective of the make or model, the vast majority of tanks that leak do so out of the airflow control valve. However, a tank that seeps e-juice isn’t necessarily defective, and can often be resolved rather effortlessly. Here are some easy troubleshooting tips on how to identify, fix, and properly maintain a leaking vape tank and clearomizer.


Step 1: Faulty Atomizer Coil:

As with all devices and components, sometimes the manufacturer will produce a dud or lemon within a given batch. Although relatively rare, you may find a faulty atomizer coil in your five-pack. Somewhere along the manufacturing process, a single coil may not have been properly assembled, which can result in leaking. It is, therefore, prudent to replace the atomizer coil with a new one to make sure that this is not the problem. This is the easiest resolution to a leaking tank, so if replacing the atomizer coil stops the leak, then you have found your problem. If this doesn’t resolve the issue for you, don’t worry, you can still use both coils once the source of the leak has been identified.


Step 2: Check Your Wattage Setting:

As most vapers know, the appropriate output wattage for your device is directly check your wattage setting - leaking vape tankcorrelated to the resistance of the atomizer coil being used. Wattage and resistance have an inverse relationship, meaning that the higher the resistance, the lower the wattage, and vice versa. If the wattage setting is too low to properly heat the atomizer coil, the result will be flooding, gurgling, and ultimately leaking. The reason for this is simple: if the output power is too low to adequately vaporize the e-juice, then you are essentially causing a vacuum effect, where you are siphoning fresh e-liquid into the head without it being heated and vaporized. Increasing the wattage or voltage to the proper setting could very well eliminate the leaking you are experiencing.


Step 3: Inspect the Airflow Control Valve:

Some vapers, particularly mouth-to-lung hitters, will often set the airflow control valve to its absolute lowest setting. Doing so restricts the tank’s air intake, forcing you to take much deeper and more forceful drags. If the siphoning intensity is too great, this can force an overabundance of e-juice into the atomizer coil, which may result in flooding, gurgling, and leaking. Try loosening the airflow setting somewhat to allow for slightly greater air intake. This may help resolve the leaking problem.


Step 4: Make Sure Everything is Assembled Correctly:

Another important step in identifying the cause of a leaking vape tank is to carefully inspect the device and its various components to ensure that everything is assembled correctly. Something as simple as the coil being cross-threaded or not screwed on tightly enough can open the way for e-juice to escape.

You will want to remove the atomizer coil and screw it back on securely, making sure that it is threaded on correctly. You also want to check to make sure the glass tube is placed on properly. With certain tanks, if the glass tube is assembled upside-down, this can also result in a leak. Once each of the tank’s components have been inspected, reconnect all of the parts securely without over-tightening.


Step 5: Look for Cracks:

The vast majority of new tanks are equipped with either Pyrex or Quartz glass tubes ascracked glass - leaking tank the e-juice reservoir. Although glass offers certain benefits, the downside is that they are prone to cracking or breaking. Remove and inspect the entire glass tube, paying careful attention to the end caps, as even the slightest crack or fracture could allow for e-liquid to seep out of it and into the airflow valve. If you do notice any fractures, this is likely the source of the leak. Replacing the tube will likely resolve the problem for you.


Step 6: Check All Seals and O-Rings:

One of the primary causes of leaking tanks is cracked, missing, or misplaced seals. o-rings for leaking vape tanksEach tank is furnished with a series of seals and O-rings. Atomizer coils are also equipped with them, all of which are meant to provide for a tight and leak-free tank. Check each and every seal, beginning with the atomizer heads. When coils are screwed on and off, the seals can be moved or otherwise misplaced. Check to make sure that all of the seals are present, not cracked, and are in the proper location. Next, follow the same procedure to inspect the tank’s seals. If you notice that an O-ring is misplaced, crimped, damaged, or absent altogether, this is most likely the source of the leak. It is also a good idea to replace the seals altogether, as the ones that came with the device may be somehow damaged.


Other Troubleshooting Tips for Leaking Tanks:

If you have tried all of the steps above and are still experiencing a leaking tank, you may need to optimize the general maintenance of your vape tank. Here are some general guidelines on how to properly care for, maintain, and use your tank in order to help prevent leaks.


Step 1: Proper Cleaning:

As you use your tank, the vapor will inevitably create some degree of condensation. This buildup is often gathered within the airflow control valve, within the drip tip, and at the outer base of the tank. It is good practice to regularly disassemble the entire tank and run it under water. Once you have thoroughly rinsed the various components, shake it rigorously and dry with a towel or paper towel.


Step 2: The Way You Hit

Many vapers enjoy taking long, forceful drags—particularly smokers who have recently begun vaping. If you find yourself sucking too hard on your drip tip, this could mean that the airflow is too restricted. Opening up the airflow valve can help in this regard. If you are taking too hard of hits, you can potentially draw an overabundance of fresh liquid into the coil, which will result in flooding and leaking. Try taking softer hits with a slightly widened airflow valve.


Step 3: Laying on Its Side

Tanks, particularly those that are equipped with airflow control valves, can often leak if they are positioned horizontally on its side for extended periods, rather than standing straight up. Vapers who have box mods can easily set their device on the table upright, as the flat bottom provides for the stability necessary to do so. Those with cylindrical eGo-style batteries will have a more difficult time doing this, as the base of the battery is generally not stable enough to stand upright. Try to keep your tank in a vertical position as much as possible, as this will greatly help reduce the possibility of leaking. Leaning it against a wall may help for those who don’t use bod MODs.

    Okay so this post was quite helpful. I bought my BF a switcher and it’s not a cheap vape so I was very disappointed when he said it was too much trouble and was returning to stinking cigarettes. The air flow vent was continuously leaking. I used this post to trouble shoot and while examining each part carefully I found the problem. The coil was the incorrect one. I only caught this because I noticed the other one looked completely different. I trusted the sales person at the local vape shop and apparently he didn’t realize it or doesn’t know his stuff. He gave me the display model which was fine with me but this was a huge headache. Anyways, problem solved! Woohoo! Thanks for the post!

    I just bought my tank two days ago. It’s a SMOK tfv12 Prince. I woke up this morning and all my juice leaked out all over my vape and my table. I had the same problem with three Fireluke tanks all brand new but still leaking 2 days after purchase. Wtf is going on? This is exactly why I switched to RDA. I have a half hour drive to work. So a tank would be useful.

    Thank you for the info. I have a Smok Cloud Beast and an Aspire Cleito 120. Both have been leaking. I will try all the above and hope for the best!

    You also do not want to fill your tank back up until it’s at its minimum liquid level. When you draw on the system, you create a slight vacuum in the tank. Once you open the cap, the vacuum is released, and if your juice is covering the liquid portholes, it will suck a bunch into the air chamber.

    If you let the liquid level get to the lowest point possible before getting dry hits, you minimize the amount of liquid sucked into the airflow. <3
