There is nothing worse than spilling yourbest e-juicein all your hands Lately, manufacturers have redesigned some of their newer tanks to combat leaks and other annoying problems like hot pops and spatter. No matter what type of device you prefer, here's what you can do to fix it now.

What is leaking?

Leaks and spit in the tank: how to repair your vaporizer (1)

Leakage occurs when e-juice escapes from your tank, usually through the airflow system. Depending on the reason, the leak can range from just a few drops of e-liquid to your tank emptying its contents into your entire vape mod. It is a common problem even with the most popular ones.Sub-Ohm-Tanques. Best sellers of the last few years, such as the SMOK TFV8 Baby Beast, Uwell Crown III, Sense Herakles, and Aspire Cleito, have problematic vapers that leak due to design oversights or common user error. Many of the newer tanks are designed to prevent this, although no tank is 100% leak proof.

While there are some common culprits, the good news is that there are ways to prevent leaks. First, we'll start with some general tips and then go deeper depending on the device you're using.

How to avoid leaks

Leaks and spit in the tank: how to repair your vaporizer (2)

check your badge- Sounds obvious, but make sure your tank is securely attached. Sometimes when you are in a hurry you can twist the top cap off or forget to screw it on tight. This can cause juice to leak through the vents. First, make sure the threads are in sync and tight, but not too tight. Find that sweet spot. If the threads cross, screw them carefully.

Remove the e-liquid from the chimney– All tanks have a central airflow tube that runs from the tank body to the drip tip, known as the chimney. Sometimes e-juice can accidentally get into this tube, usually leading to gurgling and leaking. If this happens to you, wipe it up with a paper towel before steaming.

Keep your tank upright– Some tanks are not built to lie on their side for long periods of time. E-Liquid may leak out of the airflow holes if left overnight. Try to keep your vaporizer upright if you don't use it for a long time. Don't get in the habit of constantly turning off the device or you'll have to deal with inevitable leaks.

Check for worn or damaged o-rings.– A common cause of leaks. Take your tank apart, remove the o-rings, and inspect them closely. Look for signs of wear, broken or missing o-rings. These things can affect the tightness of the tank. Fortunately, o-rings are inexpensive, just make sure you get the correct size. If you still have the box your tank came in, an extra set of o-rings may have come specifically for your unit.

put a lid on it– If you leave a tank without the top cap, it will leak through the airflow holes. This is due to the pressure nature of the tanks. Make sure your tank is empty if you plan to leave the tank cap open for an extended period of time, longer than it takes to fill your tank. Turning off the airflow also works, but it's not quite as foolproof.

Check your airflow– When inflating, always make sure the airflow openings are completely closed. When you use it, make sure the airflow is open enough so that you can vape without having to inhale a lot. If you inhale too forcefully, you risk getting too much e-liquid into the coil, which could lead to a leak.

Be careful when filling– Never overfill the tank. Always leave a small air bubble at the top when inflating. This empty space prevents the leakage of liquid. Also, be careful not to fill too quickly or you risk flooding the tank.

Check for cracks– Check the tank for cracks or other damage. A small crack in the glass or a bent piece of metal could mean the tank is no longer airtight and juice could leak out and enter the vent valve. If your glass is broken, a cheap and easy fix is ​​usually to buy a replacement.

Use the correct e-liquid– For coil heads that draw a lot of current, due to the low viscosity of PG, there is a good chance of leakage below 70% of VG. A good rule of thumb is the greatcloud releaseDevices work fine with 70% VG (only 30% PG) and above, andMTL devicesthey are generally good up to 70% VG. Always check the label on your e-juice to determinePG/VGRelationship.

Check your coil heads– As with most mass-produced products, there will always be some glitches. In some cases, the coil may have manufacturing defects that prevent it from correctly retaining the broth, causing leaks in the tank. First, make sure the coil head is screwed on correctly, and if it is, simply replace the coil, preferably with one from a different batch than the one you are currently using. If the issue persists, the complication is most likely caused by one of the other issues discussed here. You could even try buying the coils from another supplier to avoid the possibility of getting another bad batch.

wick carefully– This only applies to rebuildable atomizers, which require you to vacuum them yourself. wick oneACRcan be tricky - make sure you're using enoughCotton, or risk leakage. The objective is to insert the cotton into the openings of the wick without obstructing them. This can take some trial and error depending on the atomizer you use.

What is spit and hit?

Leaks and spit in the tank: how to repair your vaporizer (5)

Spit or spit is the name for the occasional super hot blob of e-liquid that is shot into the mouth while vaping. if you see oneRDASometimes when the coil fires you may notice this, usually accompanied by a clicking noise. Droplets shoot out in all directions, but if you're unlucky, some of them may hit the nozzle.

Spitback has a simple cause: e-liquid collects in the coil and "cooks" instead of vaporizing. It spits out like boiling water, and if you inhale through the tip, you can easily catch a drop or two. The problem is closely related to flooded coils, but in some cases it can also occur without flooding. Here are some ways to prevent spitting and popping from happening.

This will prevent spitting and popping.

Don't overfill your reel– “Prepping” your coil is the process of manually dripping e-juice onto your locks before using them for the first time. If you put too much e-juice in the chamber, it can easily cause flooding and spitting problems. Do not overdo it. Find your balance. It is better to give the cotton time to soak than to rush the process.

reduce airflow- Excessive inhalation during vaping encourages flooding, literally drawing more e-juice into the chamber. This is easy to fix: inhale more gently and let the coil and wick do the work for you. If you're still having trouble, try lowering the airflow setting. However, if you reduce airflow, be careful not to inhale too forcefully to compensate; this can only make the problem worse.

Use thicker e-liquid– PG has a finer consistency than VG. This means that high PG e-juices are more likely to flood an atomizer than high VG e-juices. If you are having problems with your Spitback, go to ahigh VG e-liquidyou can solve the problem by delaying its absorbent action.

Press the fire button- If you've injected or inhaled a lot, simply press the fire button a few times before starting to inhale. The clicks should disappear, leaving the usual white steam noise. At this point, you can already blow without fear of spitting.

connect power– If your wattage is too low, it may not vaporize the e-liquid as fast as the wick does. Try going 5-10 watts if using a variable wattage mod.

try anotherdrip tip– If you have a 510 drip tip, try an antispitback drip tip. Angled designs make it difficult for e-liquid to spit out in your mouth. Longer drip tips, especially if they are curved or bent, work just as well. You can also try putting a screen on the bottom of the drip tip or find one that is specifically designed for this purpose.

clean the chimney- While flooding is the most common cause of spitting, the problem can also be made worse by e-juice building up in the chimney, which ends up back up into the coil. This is easily fixed: take a rolled up tissue, remove the drip tip and insert it into the chimney of the tank. This will absorb excess liquid and reduce the chance of it spilling and exploding.

Avoid exotic coils– This mostly applies to Rebuildables. Multi-wire bobbins often burst and sneeze due to their construction. But twisted coils in particular get a bad rap.clapton coilsyou may have the same problem. Its design makes it easy for e-liquid to accumulate in the coil and therefore it is sometimes difficult to completely avoid explosion in these types of coils. The easiest tip if you're dying to avoid spitting up is to use plain round wire.

fix your locks– If you are using an RTA and Spitback is a problem, you may need to rewind the coils. It may take some experimentation, but the goal is to cover the channels from the tank to the chamber without completely blocking them with a tight bit. If you have problems with flooding and regurgitation, you will need to use more wick than usual, but not too much.


Sometimes troubleshooting is necessary for a smooth experience. There are many causes of leaks, saliva and hot biscuits, but they are very preventable. Start with the simple solutions first, and if they don't work, move on to more drastic measures. If all else fails, you may need a new tank or equipment.

It's good to know that manufacturers are taking notice of these common problems. With anti-spitback and anti-leak measures becoming more prevalent, we may be entering a new era of vaping. With the advancement of technology, these problems will one day be a thing of the past. In the meantime, don't let these inconveniences stop you from enjoying yourself.a much better alternative to smoking cigarettes.

Just met my first RTA, set it up with all my knowledge at the time, but went back to my Crown 4 tank after a few hits to Hot Spitback!
Thanks for the great tips on how to solve this problem! I'll try some of your solutions and see what I can find!

I am using a new GT2 coil (NRG tank) and it clicks and spits. I tried many times to clean my tank by priming everything, but to no avail. Popping and spitting is the same as before. I lowered the power to 30 and increased it to 55 watts. Turn the airflow up and down, but it's still the same friendly advice.

Hi Mohammad, sorry to hear that. Do you know the VG/PG ratio of your e-liquid? If it's less than 70%, VG may be too thin for the coils. Is it a very sweet juice? E-juice with too much sweetener can also be the problem. My suggestion is to start over with a new coil and a different e-juice. You can also try playing with a higher wattage, as the wattage may not be enough to vaporize all the liquid that might be causing the problem. Good luck.

I just bought a Smok Nord kit. We use it without nicotine and drink a more watery juice. We drive a semi truck across the country. The high altitudes caused leaks. Any suggestions on what everyone else did

Hey Laura, hey, that's a good point. Altitude can have a significant impact on e-juice viscosity and absorption. The only thing I can suggest is to keep your tank empty in these conditions. You can try a thicker e-juice next time and I hope this fixes this problem. Good luck.

I have had leak problems with almost every tank I have received. I have two Smok Baby Princes and just received a VooPoo uForce today. The first smoke tank I started started to leak, but this was fixed by replacing the pre-installed coil. On the second one I bought, I immediately swapped out the pre-installed coil for the one that worked on the first tank but is still leaking. Some guy at the kiosk took a look and turned the glass part of the tank upside down. This worked for about an hour and a half, but thenKeep reading "

Hi Trevor. Wow, this must be very frustrating. Sounds like your girlfriend has the magic touch when it comes to the tank. I'm confused as to why the thinner liquid didn't leak and the thicker ones, but in any case, she may want to try swapping out the glass section and/or o-rings if she still has the box that came with it. . You've tried? In the future you should look for another one.Sub-Ohm-Tanquethis better prevents leaks.
