DCT Flooding

[lordy]

Well, given other threads about having to further bore the little hole in the side of an atty, I have the exact opposite issue!

I don't know whether it's my draw style or what... I'm using 50/50 ag/pg so I know it's not mix viscosity.

Anyone else had/having similar? Any suggestions?

Cheers ta

I don't believe it's flooded. I think that's impossible for a duel coil. Can you tell us more details?

[cyborg]

I was thinking the same thing as you sort of flood them to get them to work.
That makes sense doesn’t it 

[lordy]

Yeah sure. When I first got it, I primed it slowly with 23 drops. I 3/4 filled the tank and it vaped beautifully for 12 hours.

After that, there was progressively worse vapour production and flavour. I even tried it on a booster cranked right up, to no avail.

It kept getting worse and worse then this afternoon, there was hardly anything at all... accompanied by gurgling sounds even vaping gently. I lifted the tank so the hole was below, and took a couple more futile vapes. I tipped the tank contents back unto a bottle and gently blew out the rest of the cart. I ended up with a palm full of hot eliquid.

I left the tank drained andin the following next few hours, vapour and flavour got a whole lot better. I've stuck with my C this evening and will go back to the tank tomorrow, but right now it vapes perfectly.

I've got a couple of spare carts but I'd rather discover the issue than fly through carts necessarily.

[cyborg]

It appears that removing the drip tip & bung (if used) then topping up the cart gets things going again.
Cant say for sure as I haven’t found it necessary so far.

Hi all,

I find vape / flavour dropping I give a couple of cold hard draws to pull juice into the carto, if that isn't enough as Cyborg says drip tip off, bung out and top up.

Only had to do the later once/

I used the mega DCs a few times and had a stupid tendency to over-fill them. After juice leaked through the bottom and the fluval was over-saturated, vapour/flavour production went down and rather than crackliing when fired, it gurgled. This is exactly the same as what the DCT is doing at present.

I've seen people say that the fluval gets dry at  the top after a while but I've not been having this problem. If I leave the bung in, I get a layer of eliquid sat on top of the bung that dribbles down the drip tip and unpleasantly into my gob. Without the bung you can still see a layer of eliquid start to sit on the fluval, which can be shaken out without effort.

I'm sure it's over-feeding for this to be happening?

Hey lordy,

Perhaps this is a technique thing? I've been using the DCT with the bung in and whilst there is usually a small build up of liquid on top of the bung, it's never been enough to dribble out of the drip tip.... that said, I've not had the DCT flood on me either.

Still loving my DCTs and the first cartos are still going strong after almost 7 days of solid use and not showing any signs of giving up yet

[Rtsjr]

I've noticed that if you over fill it (which is only a drop or two extra at most the rest leaks out), the first few hits are harsher and less vapor is produced. This only happened to me for a few hits after filling then went on vaping nicely. Just like the eGo-C, after it gets too wet or for lack of a term, flooded, it only takes a few very slow (activated) hits to get the extra juice to vaporize.

Actually, I take that back Started to get hard to draw on the 3.5ml today, blew down it and blasted out dark liquid and crud onto a bit of tissue. I'm not arguing with 7 days of pretty heavy vaping but any suggestions on squeezing a little more life out of it would be great

I guess boiling is the only hope?

[lordy]

Hi Tez,

Boiling works and works well... but Pufferfish also said that you can flush with pg/vg too. It's not as thorough as boiling but does the job much quicker.

[tez77]

Cheers lordy... bit of both then maybe

[Rtsjr]

Boiling possibly could work. I've never tried tried but if the boiling water can loosen the gunk on the coil enough to break lose it's worth a try. Just to be safe I'd use de-ionized or distilled water for boiling but if you were going to bin it anyway it doesn't really matter right.

[Pit Vaper]

Here is something else you can try, that I learned from another tank user.  After you have inserted the carto into the tank and filled the tank, there should be a pocket of air at the top, just butt the carto against the seal (o-ring) and the then tip the tank on it's side so that the air pocket is above the drilled hole in the carto, then go ahead and force the carto on through the seal and pop on your drip tip.

From what I understand sometimes when you do this proceedure with the drilled hole below the liquid level it can sometimes create pressure inside the tank which ultimately forces your liquid into the drilled carto hole causing it to flood.

Hey it's worth a try

Yep, have boiled a few atties before and only ever used tap water, never been a problem but then again, can't say I've ever had fantastic results from boiling them. As you say, it was only going in the bin so worth a shot.

As an additional plus (which kinda makes boiling the carto a waste of time really), I finally managed to get all of the sticker off one of my 510 XL DC Cartos and it will indeed fit inside the DCT, just gotta punch it now and im good to go, thats fantastic news for me since I have about 40 of those original DC cartos kicking around

[tez77]

Lordy... how are you storing/carrying your DCT?

The only reason I ask is that I was sat fiddling with a new DCT that I opened yesterday and I noticed that everytime I moved that tank up the carto slightly there was an air bubble appearing from the carto hole. I just wondered if your tank was being moved a lot from being in your pocket or something, could it be pulling in liquid all the time, hence flooding after a while?

A long shot perhaps, IDK 

[The Vape Escape]

Hey folks,
 So I've been following your systematic elimination of possible causes for the flooding.. I'm sure you will solve it eventually!  I only just got mine yesterday, so cant offer much assistance to be honest, but touch wood so far mine has been great. Though I did I have that same gurgling sound at one point on mine also, coupled with poor vapour production etc.. I was fortunate that removing the cart and giving it a quick blow through seemed to solve it.
  I was thinking Lordy, and I know that after all you've tried, that this will sound overly simplistic, but could it not be possible that one of your Atty coils has packed up and so it's only running on one functioning coil? So therefor can't hande the amount of juice being dumped into it? I don't even know if that's even possible as Ive no idea how they're wired but just thought I'd throw that out there!

Interesting thought, it would certainly be possible as the coils are hooked up in parallel circuit.

[lordy]

Hi guys thanks for all the helpful replies.

Well, I tried everything with the last carto. I even dumped all the juice out of the tank and spent several hours trying to get a vape out of the carto on its own - the thing was still sopping wet so I think you were right VapeEscape.

I filled a fresh carto this morning. It's only been an hour but so far so good.

Am a bit gutted that a carto would fail after 12 hours of use!? Hopefully it was a one-off. I've got one more spare so will see how these two last before stocking up. Fingers crossed it's fruitful - still love the idea of all day hassle-free vaping. Given the high number of happy forum members my experience must be the exception not the rule

[tez77]

Hopefully it was just a one off lordy. Are you able to drop a multimeter on the offending carto and find out its resistance?

Not immediately Tez - there's one at myMum's house so will try it next time I'm over

Sure, that would certainly show if one of the coils is down. Of course if you're not intending on sending it back to TW you could always take it apart carefully and see if/how both coils glow when on a battery.

[lordy]

For a couple of quid's worth of equipment sending it back is a bit of a hassle! Think I might just disassemble as you suggest.

A couple hours in with the new carto and I'm seriously impressed! It's breaking in now and the vapour production really is out of this world. I'm vaping it the same way as I did the last one but the difference is immense

Agreed, never worth the hassle.

They are good aren't they

If you do take the DCT carto apart and you have a stock of the old 510 XL DC Cartos then you can swap over the outers and utilise the old DC cartos in the DCT.

[kondor]

I have one and it too decided to go for a walk at about 12hrs of use ,  actually it was more like 1ml of use.  Had a burnt taste to it too which makes me think it wasn't wicking properly either.  Although the level of the liquid in the tank had dropped by a good 1/3rd of a tank over that time so I assumed that it was wicking, until I got the taste.  

Left it for a day then checked, had a peak and sure enough it was flooded.

I do not think this system works good enough for the general public yet.  Maybe OK for experimenters that just want to evaluate a proof of concept but thats it.  It is my own fault for buying it.  I should have known that when someone says that they have adjusted the hole to 1mm from 0.8mm that something has not been working and is still going through the concept stages.  Stupid me for taking a gamble on a product that has not really had a proper road test in the wild.

80/20 pg/ag if anyone is interested.

One good thing I guess,  I have a new drip tip and tank now.  But there is no way I am going to buy one of the current batch of cartos for it,  I will wait until the next version come along.

PS,  how are you supposed to use a multimeter to test the coils if they are in parellel and identical?

[Astrecks]

I think the nub of the matter is in an ideal world it would be better if you could organise an adjustable hole size, that way you could probably adjust it to your own vaping style. The increase in hole size was based on feedback and experiments on the original hole size of 0.8mm, but it does not suit everyone

I wonder if it would be possible for them to be manufactured with a couple of different hole sizes so that people can make up their own minds. Would also help people using more of an AG mix perhaps.

[kondor]

What would happen if you filled the tank part with blue fluval?  It might work better because you have a little bit of wicking action going on inside and outside the carto. 

If you think about it the two sides are always going to be trying to reach equalibrium, which as far as we are concerned means that the inside of the carto is going to want to be as wet as the tank.  Which really means the carto will always want to flood.  But by adding some sort of material to the tank we are making the tank more like the mixture of fabric and liquid inside of the carto, therefore moving it closer to an equalibrium.

As the Carto dries, it will fall out of this equalibrium and therefore wick juice from the surrounding tank. 

Tank needs a filler of some sort, then the hole size is less of a concern. In fact it should be able to have several holes without it causing a problem.

Meh, I haven't got a carto now,  will have to wait for my next order (going to get spares for my trusty microlites)

PS, I think that because there is a chance of quick failure rates then TW should add a couple of quid to the price and sell these with two or three cartos.  I think some folk will be angry that they can not use there new device because it only came with one carto.

[lordy]

Have to say Kondor I think you may be basing your opinion on one carto? Understandable - I was hanging on to my first carto and willing it to work properly before giving up and trying another.

I'm using 60/40 AG/PG and am having the opposite problem this time - I'm having to take a couple of quick hard cold draws (til I get a few air bubbles) and it seems it's not quite getting wet enough. I'm only having to do this once an hour but still, bit of a contrast to my last experience.

You could well have a coil gone too? Honestly the difference between this one I'm using and the last one is the difference between night and day. I'll keep you posted how long this one lasts, but on this performance, there's not a lot wrong with the setup.

Not sure if that's true though. They don't really differ from the old 510 XL DC cartos and I dont think I've ever had one of those that failed.

I could of course be wrong (it happens from time to time  ) but i'm on my 3rd now (although one is a converted 510 XL DC carto) and they've all worked well so far.
