Ok, it's not a cleaning issue then unless you've had them for a long time already. The issue now then can only be that it's not wicking the eliquid fast enough.
The tank system is good, if it works. But getting it to work is the hard part. Here's a few pointers to consider trying out.
- Do you use more vg or thick eliquid? It will be harder for the tanks to wick, use thinner liquids if possible (ie greater pg content)
- Make sure the cartridge is on all the way. If it's new it should 'pop' in until it's snug against the atomiser.
- Do not completely fill the cartiridges. Make sure there's a small air gap in there.
- Tanks work on negative pressure: sucking through the cartridge will force some eliquid into the wick.
- Leave your tanks upright. Gravity will pull juice into the atomiser over time. Give them plenty of time to soak juice up this way.
- Make sure there's no plastic flap left on the inside of the cartridge after piercing them as it can restrict eliquid flow.
Ok, those are basic non effort pointers but there's more you can try to do that's going to be a little more difficult or risky...
- Using a very thin needle, poke a small hole against the edge of the wick inside the piercing straw. Less is more; if you pierce too big a hole too deep it'll simply leak every time. If you do this, don't bore a hole too fast; deepen the hole, give it a few minutes and if it's still too dry, deepen the hole again and repeat until it's wicking.
- Instead of the hole method you can use something that will fit in the piercing straw and gently podge the wick down a little. As with the hole method, make sure you don't push it too far too fast. Little by little and test each time so you don't push it much too far into the atomiser. If you push it too far in you'll have to take the plate off the bottom to pull it back up and it's a real pain to do.
- You can also (but this is really not convenient) use a blunt needle and put eliquid into the threaded end so it gets juice into the atomiser this way.
I wouldn't be disheartened, tanks work for some, others it just never seems to. You have options though. I'd try out a cartomiser pack if I were you
Electronic Cigarette - Cartomizers - Boge Cartomizers it's the 'known to work' portable vaping solution, where everything else has wicking or leaking problems that's actually affordable. 2.5ohm boge cartomisers will be a nice warmth, 3ohm will be very cool and much less vapour, 2.0ohm will be hot and a lot of vapour. If you don't get the tanks working with these suggestions then cartomisers are just an option you can use instead with the batteries you have now (provided the cartomisers are 510 version).
