EcigFuture: Guide to Troubleshoot a Leaking Tank

  1. Filling the Tank correctly

One of the most common causes of tank leakage, is also the easiest to fix. The tank set-up has a central airflow tube which the vapour production comes out of. We call this the ‘Chimney’. If at any stage during the filling process e-liquid enters this tube – you will experience leaks and gurgling. To avoid this read the instruction manual that comes with the kit to double check you are filling the tank correctly. If e-liquid does enter this tube accidentally (which it does happen even to veteran vapours!), simply clean out the residue with paper towel before you continue to vape.
Another useful tip: do not overfill your tank, always leave an air pocket at the top to create a vacuum to prevent any e liquid from leaking.


  1.  Check your O rings

O-rings are what creates the air seal for your tank. If one of these is worn or damaged your seal will not be working properly and leaks can occur. To see if your O-rings are intact, take apart your tank and examine them thoroughly. If you see any damage, wear (or they are completely missing) this could be a cause for your leaks. Replacing your O-rings will rectify this, just make sure you buy the right size for your tank!


  1. Check your seals

Leaks can also occur if the tank isn’t fastened together properly. Double check all threading to make sure they are aligned. Once you check these ensure all components are screwed tightly, but not too tightly as this can cause other issues.
It should be firm enough for it to hold, but be capable of being unscrewed without too much resistance.
Remember: be mindful to check if the threads have worn from use. If you have attempted to screw and unscrew the device to no avail – it may be time to replace your tank. But if you have a top filling device, it is highly unlikely to have wear on your threads – and the materials they use are usually pretty sturdy stuff!


  1. Keep your tank vertical

Sometimes leaks can occur simply because of gravity. To avoid this type of leakage out of the air holes, try to always leave your tank in a vertical position if leaving it for a long period of time. Similarly, when charging your device, it is recommended to remove the tank and sit in an upright position


  1. Close airflow when filling

The airflow component of your tank sets how powerful your inhalations need to be to vape. To avoid doing this too forcefully and bringing unwanted eliquid into the atomizer coil, which can flood the tank and cause leaks, open the airflow to a larger gap to allow more air through the atomizer. When filling your tank with e liquid, you must have the airflow closed to avoid any leaks.


  1. Coil problems

Sometimes you will come across a few faulty products. Unfortunately, it is unavoidable with mass produced products, especially if the product is coming from overseas where the same safety and regulations standards are practiced.
If you come across a bad coil, our advice to you would be to avoid using that batch as all the coils could be affected. Ensure your coil is screwed in firmly, if it is try another coil from a different source. If you are still experiencing the same complication then the issue is probably one of the other points discussed in this article.


  1. Clean your tank

Just like any container holding liquids, they need to be cleaned from time to time. A build-up of old residue could cause complications for yourself. To avoid this, take apart your unit, wash the tank in cold water then leave to dry out completely before putting it back together. To do a thorough cleaning of your tank, you can use a small amount of dish soap and warm water. Cotton ear buds are useful to get into the tricky corners. If you find yourself switching between flavours, you may have to do this more often.


  1. Check for cracks

If any cracks or damage happen to the tank, it will affect how airtight the tank is, and allow e liquid to leak into the air hole valve. You will require a replacement tank in this case.


  1. Use appropriate juice viscosity

Some coils require a significant amount of power, for these tanks any e liquid used that is lower than 70% VG, due to thinness of PG, has the high likeliness of leakage due to the larger ports that these tanks sport. The instruction manual that comes with the kit should indicate what viscosity should be used. So, for the big cloud producing devices a 70% VG and 30% PG and above is recommended, and MTL units are usually preferable to use UP TO 70% VG. Always check the label of your e liquid to check what PG/VG ratio you are using.


  1. Keep a lid on it

Tanks are pressurized. This means that if you leave the top cap off your tank, it will leak out of the airflows as the pressure is not correct. It can happen to the best of us, we all get distracted from time to time! If you want to leave your top cap off for any reason for an extended period of time, ensure that the tank is empty before you do so. You can close the airflow off which will help, but it is highly recommended to have the tank empty if you wish to have the top cap off.

Temperature Control [aka TC] Devices

TC & The Reactor Range

The Reactor Shorty is an advanced sub ohm vaping device, capable of setting the actual temperature of the vapor. This is needed for any Ni200 coil, as they should never be used in variable wattage mode.
Scroll down to the “Coil” section for more information as to why the nickel coils should be used in the TC mode.

You can change the mode from wattage to one of the TC modes on the Reactor Shorty by pressing the firing button (3) times. When you see the display switch to showing the current mode, use the up/down buttons on the bottom of the device to cycle through the modes until you find the appropriate mode.

NOTE: The device will give you a “Temp Protection” message on the display if you set the temperature below.


E-Liquids to Use With Reactor Shorty

All e-liquid blends contain two basic ingredients; Vegetable Glycerin (VG) and Propylene Glycol (PG). We have two ratios, one that is higher in PG and one higher in VG. The recommended ratio depends on the hardware type being used.

VG is a thick, sweet tasting base that creates a smooth lung hit, and dense vapor clouds. Sub Ohm units, better known as mods, works best with our High VG liquids [70vg/30pg].

In comparison, PG is a very thin base and does not alter the flavor of the liquid. It does however, help contribute to the “throat hit,” that many former tobacco users are looking for when first transitioning to an electronic cigarette. Traditional e-cigs will work best with the Standard formula, which is higher in PG at 70pg/30vg. So, if you are using this type of liquid, you will want to move to a high VG liquid.



You want to choose your nicotine based around the types of cigarettes you were smoking, not how much you were smoking.

To put the nicotine levels into perspective for traditional sub ohm units like the Reactor Shorty.

– 1.5mg/ml is comparable to Ultra-lights, the 3mg/ml is like lights, and the 06mg/ml close to full flavored.



In regards to the Reactor coils, we have three material types: Kanthal, Ni200 [nickel], and Stainless Steel. The resistance level is basically a personal preference; the lower the ohm, the hotter it will heat the e-liquid. The coil material is also a personal preference.

The Mini, Mega, and Shorty Reactor units all have TC [temperature control] modes, where you can use Stainless Steel, or Ni200 coils in the tanks and adjust by temperature, instead of wattage. These TC coils are intended for users who are looking to fine tune the actual temperature, instead of adjusting the wattage.

Kanthal coils are not TC coils and are only used in wattage mode. They remain a very popular coil type for their stable resistance at varying temperatures. The Clapton Kanthal coil is a braided coil, which has more surface area to heat the liquid, resulting in more flavor.

Ni200 are pure nickel, and it has a high temperature coefficient; which means that the resistance increases, the hotter the coil gets – therefore, the Ni200 coil type should only be used in TC mode.

Stainless Steel coils heat up much faster than other coils due to the steel being naturally low in resistance. These coils can be used in both variable wattage mode, and the “SS” mode on Reactor Mini, Mega, and Shorty units. Though most customers who are used to Kanthal coils seem to prefer to use these in TC mode only. You can buy your reactor coils here.


General Information

If you are having a continuous burnt flavour after just a few days, there are a few things that can be at play here. One of them could be using the device in variable wattage mode, and not the appropriate TC mode for the type of coil you have. If using the Ni200 0.25 ohm coils that came with the device, you will want to set the device to “Ni” mode right away. Also, if you have been using the Ni200 coils in wattage mode, you will also want to replace the coil prior to continuing use of this device.


Vaping Technique

Do Not Chain Vape – If you take frequent back to back hits, you are going to burn out the coil much quicker! You also can flood the coil, which can spit liquid in your mouth, and leak from the air vents. Wait at least 30 seconds in between drags.

Keep Tank Full – It is fine to let the liquid get a bit low in the tank however, if you are a heavy vaper, you will want to keep the liquid above the top of the coil as often as you can to prevent the wick sheets from not getting enough liquid to them.

Firing Button – Only press the firing button just before you start taking your drag, and ALWAYS let of of the firing button BEFORE you stop inhaling. This way you will clear all of the vapour created each puff. If you do not clear all of the vapour in the airflow chamber you can flood the coil, or if you hold the firing button down too long, you will burn out the coil much faster.
