It sometimes happens that you encounter problems with leaks or e-liquid rising with your e-cigarette. You may have the unpleasant surprise of finding e-liquid in your bag or pocket. 

Sometimes a few drops of hot e-liquid even reach your tongue when vaping. It is good to point out that this kind of concern comes exclusively from the clearomiser and not from the electronic cigarette. Rest assured! No need to throw away your vape, here are the 6 scenarios that can occur and the appropriate solutions to prevent your electronic cigarette from generating liquid drips or droplet projections.

1- Your way of vaping

Problem : 

When you start in the vape, you tend to pull on your e-cigarette like on a traditional cigarette. However, strong and frequent draws do not always go well with an e-cigarette. Indeed, by strongly inhaling the vapour, you risk exceeding the vapour production capacity of your e-cigarette and consequently, causing the liquid to rise in the central chimney and the drip tip of your clearomiser (with the risk of projection of droplets and gurgling).

Solution : 

Vaping an electronic cigarette requires a slower and more spaced-out suction time than on a real cigarette. It is recommended to inhale gently for periods of about 5 to 8 seconds, then to space your inhalations by 15 to 20 seconds. This period will allow your e-liquid to properly soak the cotton of your resistance to prepare your next suction.

2- Condensation in your clearomiser

Problem  :

When you vape, vapour (condensation) comes out of your clearomiser through its chimney and then the drip tip (mouthpiece). It is normal for a little condensation to remain along the walls of these because as it cools, this condensation turns into fine droplets of e-liquid. This phenomenon is also accentuated with sub-ohm clearomizers (<1 ohm) which generate much more vapour.

Workaround  :

Release the power button ( switch ) of your e-cigarette shortly before the end of your aspiration. You will thus stop the production of vapour while continuing to suck up the rest of the vapour present in your clearomiser. This will reduce the effect of condensation.

For a sub ohm clearomiser, opt for short and wide drip tips which will reduce the effect of condensation on the walls. Before you start vaping, you can also wipe these droplets directly from your drip tip with a tissue.

3- The wear of your resistance

Problem: The majority of leakage problems come from the wear of the resistors. The cotton (wicks) of your resistance no longer absorbs your e-liquid correctly and allows the liquid to pass through the chimney of the clearomizer.

Solution: Change your resistance every 2 to 3 weeks maximum (corresponds to 15 to 20 fillings in e-liquid ). A change in the taste of your e-liquid or blackening of the cotton of your coil should alert you, it’s time to change it! Remember to properly prime your resistors during their first use by letting the e-liquid soak for 5 minutes (and at the same time avoid dry hits .)

4- Poor filling of your clearomiser

Problem  :

A clearomiser overfilled with e-liquid generates pressure on your resistance in the event of variations in heat which can cause leaks on your clearomiser.

Always leave a few millimetres of air space in your clearomiser (2 to 3 mm min) when filling the e-liquid.

5- A bad assembly of your clearomiser and deteriorated seals

Problem: A clearomizer can leak through the airflows (air inlets) due to damaged seals. Over time, the heat released by the resistance of your e-cigarette can dilate your clearomizer seals and thus make them less tight.

Solution: When you clean or change the resistance of your clearomiser, be sure to assemble each element ( base, resistance, seals, top cap, Pyrex tank, drip tip ) and the correct tightening of your resistance (without crushing the seal too much) to ensure a perfect seal. Also, check the correct positioning of all the seals as well as their integrity. If in doubt, replace them with new seals. Do not hesitate to close the airflows of your atomizers and clearomizers when you’re not vaping.

6- E-liquid / clearomizer compatibility

Problem  :

Depending on the model of clearomizer you use, it is recommended to use an e-liquid whose viscosity ( GV / MPGV base ) is adapted. For example, you will have problems with leaks on sub ohm clearomizers (resistance < 1 ohm) if you use fluid-based e-liquids (little GV and a lot of MPGV ). Similarly, depending on the clearomiser used, if you do not send the necessary sufficient power to your resistance, your e-liquid will have difficulty evaporating and will boil (the famous gurgling effect that we hear).

Workaround  :

It should be remembered that the standard ”  small clearomizers  ” are designed for fluid e-liquids, with a maximum of 50% Vegetable Glycerin. The more efficient clearomizers called “sub-ohm” (< 1 ohm) are used exclusively with thick e -liquids beyond 50% Vegetable Glycerin . Also respect the ranges of use in watts expressed on the resistors of your clearomisers to facilitate the generation of vapor .

Despite the solutions provided by this article, it sometimes happens that the leak problem persists. It may therefore be a manufacturing problem with your clearomiser or your coil .
