How to Stop Your Tank Leaking

1 – Make Sure You Fill Your Tank Up Properly

Want to know what causes most leaks?

It’s how you fill your clearomiser.

All tank style atomizers have a central tube extending from the coil up to the mouthpiece.

If you get e-liquid in there, you’ll almost certainly run into problems with leaking or gurgling.

The fix for this is simple…

Ensure that when you fill up, you avoid getting any e-liquid in the central tube.

Tilt your tank when you fill up, like you’re pouring a glass of beer.

This ensures the liquid runs down the inside of the glass or plastic of your tank – and stays as far away from the centre tube as possible.

As it fills up, gradually straighten the tank to avoid spills.

If you do manage to get liquid down the central tube, make sure that you clear the excess before use by:

  • holding some tissue at the end, and blowing the excess out of the bottom.
  • or by flicking the clearomiser into some tissue

Don’t Overfill The Tank

Leaving a small amount of air actually creates a vacuum inside the tank which helps hold the e-liquid in the chamber.

2 – Tighten Everything Up – and Watch Out for Cross-Threading…

There’s another basic issue that can lead to leaking.

And that’s when the various components aren’t securely screwed in.

Gaps:

  • where your coil meets the base of your atomizer
  • or where the base of your atomizer meets the tank

can be enough to create a leak.

This is easy to avoid. Take time and ensure that:

  • when you re-attach your atomizer head to the base (or to the top of the central tube, for top-coil clearomizers)
  • when you re-attach the base to your tank

everything fits snugly.

You should also check your atomizer head even if you haven’t done anything with it specifically, because its connection can sometimes loosen when you unscrewing your tank.

The biggest problem you’ll encounter when screwing everything in is “cross threading”.

That’s where the threads on the two components you’re screwing together don’t line up properly, leading to an imperfect seal.

the best solution to this is to:

  1. line everything up
  2. turn it anti-clockwise until you hear a click
  3. screw it in clockwise

3 – …But Don’t Over-Tighten

There’s one problem with this…

And that’s when you over-tighten.

O-rings are tiny rubber rings. You’ll find them near the threading and where two parts of your tank meet.

They are key to making a perfect seal – and reducing the chance of leaks.

However, over-tightening can damage these little helpers.

And a little split or break gives e-liquid an “escape route” – meaning you end up with juice leaking out into your pocket.

(Which is embarrassingly close to somewhere you really don’t want e-liquid!)

Of course, the line between tight enough and too tight is a little hard to define.

The basic lesson is to screw everything in place firmly, but remember that you shouldn’t need to put much strength into it.

There’s no need to Hulk out; screw it in so it fits snugly – but not as tight as you possibly can.

4 – Leave the Tank Standing Up

When you are not using your vapouriser, or even in between vapes, the unit should be left in a vertical position.

This doesn’t matter as much when the tank is full. However, it definitely has an effect when the tank is under half-filled.

This is due to the “juice holes” in the coil.

When it is full, the holes are covered with juice and it is hard for the e-liquid to escape.

However, when it is under half full, and not stood up, some “juice holes” come out of the e-liquid. This makes it easier for juice to seep through the coil, and into either the central tube, or out of the air flow holes.

5 – Use the Correct Coils for the E-Liquid To Reduce Leaking

Most tanks come with replaceable coils with varying resistances. These are suited for doing different things.

Higher resistance coils (above 1 ohm) very much imitate a cigarette in the way that they are used, and therefore tend to have smaller juice holes. This is ideal for the higher PG (thinner) liquids as they can flow easily.

High VG (thicker) liquid used in one of these coils may clog up the coil a lot more quickly.

What’s more, higher VG liquid vaporises at a higher temperature. This can cause excess juice problems because the coil can’t vapourise the liquid properly.

Low resistance coils (below 1 ohm) should be used with higher VG (thicker) liquid, as the juice holes and air flow holes are generally a lot bigger to allow for the thicker liquid.

If you try to put high PG (thinner) liquids in one of these coils you’re likely to flooding issues. These coil allow too much thinner liquid into the coil, which will end up either in the central tube, or leaking out of the air flow holes.

6 – Check Your O-Rings and Replace Them if Needed

It’s not just over-tightening that can lead to issues with O-rings.

They can also degrade or get budged out of position over time, and may just be faulty when you first receive them.

To check your O-rings, take your clearomizer or tank apart – this usually just requires unscrewing the various parts – and look for the rubber rings on the atomizer head and at the base of your tank.

You should be able to see if any are degraded or out of position. If they are, remove them– and replace them with fresh ones.

Something like a small flat-head screwdriver, a toothpick or a pair of tweezers can help with this.

Some tanks will come with spares, but if not, you’ll have to buy some more in the correct size.

It’s also worth checking that your O-ring is installed correctly, so everything fits together with no obvious gaps e-liquid can leak through.

Could sub ohm atomizers’ coil head be self-made?

Many vapers want to make the sub ohm atomizers’ coil heads by themselves to save cost. Actually the structure of this kind of coil head is very complex, which makes it harder to build than RBAs. Misplacing of the coils will lead to touching with the metal tube of the atomizer and therefore causing short [...]

Could the coil heads be washed?

Some RDAs adopt trick coils. Because of the complex structure, it’s hard the make the coil head. Therefore some vapers may dry heat the coils after a certain period of use, and wash the burned red coils directly with tap water. By repeating this process the carbon deposition could be eliminated. Pay attention to protect [...]
