EDIT: See second post, with another more successful attempt, as well as an explanation of the problem i was having

Background: So, I have been vaping on and off for quite some time now. I usually buy a new mod now and then, and enjoy it, but usually just alongside my standard camel cigarettes.

I decided recently I need to quit smoking to avoid future health problems.

That brings me to last week. I looked through my collection of e-cigs, each interesting, but flawed in my eyes in one way or another. I checked out the forums to see what new mods or trends are appearing, and stumbled upon the tank mod. Tank mods look awesome, they seem to solve my solution of dripping constantly. I find standard cartidges run out too fast. Cartomizers seem pretty good, but still require refilling to maintain great flavor. I tend to be a dripper, but a couple drops only last 3 or 4 long drags in my 5v favorites, so it seems I just never stop dripping.

The order:

I ordered a black delryn DCT MAP tank, along with three pre punched cartos, some juice, and a new tip.



COV shipped my items quickly, and I was very happy with the packaging and delivery time.

Alright! Time to put this thing together!

At first, I was a bit puzzled as to how to properly fill the tank mod. I actually emailed COV asking if I needed a syringe, alas I had forgotten how to google things at that time. So, a quick search or two later lead me to two videos on youtube of some vapers teaching me how to fill the mod.

It seems quite simple, and it was. I take the endcaps off the clear tube, slide the carto through one of the endcaps, throw a few drops in the carto, attach the tube, fill the tube up, and attach the other end cap. Awesome. Now I am ready to go.

At this point, I had my 5v Kens Boxmod ready to go and snapped a victory picture.



So now to test it out. My first few drags were not that great, because the atomizer was flooded.
No big deal though I thought, it is probably my fault, perhaps I was a bit over zealous with my initial carto wetting. I took another hit or two and realized my hand was wet. I looked down at my boxmod and realized it was covered in ejuice, a quick inspection later I came to found my entire boxmod was covered in caramel tobacco flavored juice. Crap.









So, after cleaning the juice off the entire mod, I went to the sink, cut my losses with the current juice, and washed out the tank.

I cleaned the PV up, and prepared to try once again. Maybe this was a fluke. So I took everything apart, put it back together, and I ended up with a juice coated boxmod again.

I think its time I give up on the tank and ask COV if I can return it.

I love the idea of the tank, but it seemed to be a leaking catastrophe. My PV is juice covered again, my fingers are tingly from all the juice that was on them, and I am left pretty disappointed.:facepalm:

So, has anyone else had a leaky MAP DCT tank? Has anyone come up with any solutions to the leaking or did I just get a bad apple?:blink:

Same problem I'm having. I cringe to think about how much juice I've lost so far... not to mention the angst over getting it all over my favorite wood mod. The juice is coming out of the battery connection hole at the bottom... the o-rings are sealed and no signs of leaks there. The last time I filled it I just watched the juice drain out the battery connection like a faucet. I only filled the tank halfway and I'm holding it perfectly upright with both caps on so I'm stumped as to what's causing it. Let me know if you figure out the issue and I'll do the same. My only hope is that I got a bad carto but who knows.

***did some more research tonight and there may be a couple things going on here. 1st, the punched holes in the carto may be too big which is allowing too much liquid to wick into the carto, saturate the filler, and flood the atty inside. That could explain the instant leaking from the bottom of the carto battery connection almost immediately after refilling. The solution would be to get a new carto, punch 1 small hole instead of 2 large ones, and see if the problem resolves. 2nd, the carto itself could be faulty. I read a couple of posts on ECF and saw a YouTube video stating that switching out cartos solved some people's carto leak issues. 3rd, too long or hard of drags on the carto can cause the juice to wick up and over the filler, down into the tube and out the bottom of the flooded atty. This also results in a mouthful of juice or heavy gurgling. So shorter, shallow puffs might cure that. Hope this helps and I'll see if it does for me!

Just got mine. Initial fill was ok, then I wanted to add some more (fruit) juice, as I didn't like the inital plain Vanilla fill.
So I tried to take the cap off again, which broke two fingernails (I'm male!) And then the whole table was flooded.
After I couldn't fill it completely, as it ran out on the bottom, and somehow closed it after all. Everything was soaking wet.
After about ten slight puls holding the whole thing horizontal it became vapable as long as I didn't hold it upright.
I'm not a beginner, and love the FOG which is said to be a "complicated" device.
I think they should definitely add a instruction manual to this thing.
Also I could imagine the O-Rings (inside and outside the caps) won't love it very long beeing tortured on every refill!
Kind regards
Martin

@Greatdane: Well, I am using the pre-punched carto that came with the mod. It would seem strange that the carto they gave me would not be punched properly. I purchased a couple spares, I will try on a different device and with a different carto and see if I have the same leaking problems. Of course, the cartos I have are both punched with two holes, so it might keep happening.

@Marst: It would be nice if it had a little manual for sure. I wonder if o-rings are the problem now.

I am going to do this over, and take lots of pictures or video along the way. We'll see how it turns out.

Tried the liquinator here, and after 2.5 ml of juice disastered in my taxi...welp, not a happy camper. Also ran into serious flooding issues later on a couple cartos. Yet another seemed fine. Turns out there were o-ring issues...but the flooding crap...my opinion is if you have to hammer/n/nail a mod, or dremel a mod, or hacksaw a mod....yer asking for problems. It would be my bet that something is getting buggered seal wise in the carto as none of these things were meant to be sliced /n/ diced. My liq. is now in the vaping natural history museum right next to my njoy batteries and the xhale kit and the cheap ... cartridges and..... :D

I really enjoyed my tank, the first one a liquinator, for the first 2 tank fulls but then the cart seemd to be unable to vape anymore and unlike the clear carts these dont clean up well, so thats a $2 cart evry day instead of getting 10 to 15 days from a dual coil cart. I did not have leak problems but my 4 tanks now sit on a shef with 35 of my mods that are dust collecting as well.

Try using dual coil carts and this will fix your issues totally, they come in various sizes from 1.5ml to 5ml hoosierecigsupply is where I buy mine and now everything else just sits on the shelf.

So, I believe I have solved my problem.

I was getting a ton of juice leaking everywhere. This time, I changed devices, from a Boxmod to a Screwdriver Mk II. I also changed cartomizers, but I don't think it really mad a difference.

I had a 901 to 510 adapter in my e-cig supply box, so I put that on the Screwdriver so I could use the COV cartomizers I got with my tank.

Okay, here is how I started:



I put the first end cap on:



Then the clear cylindrical part:



Then added some juice, please note the juice level:



Then, I attempted to put the top cap on. I ended up stopping and taking another look at it. If you look, you will see it appears the juice level has dropped considerably. I believe this is due to the pressure caused by me putting on the top end cap. I believe these pressure pushed a lot of the juice into the cartomizer.



Next, I added a bit more juice, and tried to get the cap on again. This time I was successful. But then the leaking began



The great thing about using an adapter is it allowed me to see where the juice was coming from. This time, I knew the juice was leaking from in-between the carto and the contact, it was not my tank leaking after all. I am pretty darn sure that the juice that's being pushed out from beneath the carto is just cause by the pressure of putting on the lid to the tank. The leaking continued to get a bit worse...



But then it stopped, and I cleaned up the juice



And now that the pressure has been balanced, its no longer leaking and put together well.



Its been laying horizontally on my desk for about 20 minutes and hasn't leaked a drop. I guess the problem before was just pressure. Unfortunately the atomizer contact on my 5v mod is flush with the body, so I couldn't get a good view of where it was leaking. By using this extension I was able to pinpoint the leakage and draw a conclusion based upon better knowledge.

I hope this helps someone who has a lot of leakage due to pressure! Good luck!

I haven't vaped with it yet, batteries are still charging. I will let you guys know how it works later!

I have had the flooding problem too with my DCT. When filling I put both caps on 1st before inserting the carto and then move carto down so that the punch hole is visable and then tilt the carto and fill with juice and then push carto up into tank. If the top cap is put on after you fill and then inserted the pressure will cause the carto to flood. I got a suggestion to put some VG on the bottom O-ring that makes contact with the carto. This worked for a few days but last night having the same problem again. I think the issue is with the O-rings. They need to be thicker so they hold the carto into place tightly which should keep the vacuum preventing the over supply to the carto. When the DCT Map Tank works it works great but it is another example of a vaping product that has been rushed to market without intensive testing with us paying for the privledge to be beta testers.

I've read so many posts about leaking tanks and in 99.9% of the cases the problem is the Dual Coil Carto!! Tanks don't leak, carto's do. Let me just cut to the chase. USE BOGE CARTO"S! I don't know if they fit in the DCT Tanks because, I suppose, they're made for Dual Coils. There are many other tanks on the market that use Boge carto's. Some have other problems like not being tight enough or cracking tubes but some are just fantastic. Vapor-Age just came out with the Depth Charge which is excellent. Jonboyusmc has a thread about his unique Lava Tanks that work great. The Cartomator from Nhaler seems to be problem free. Stay away from Dual Coils! They leeeeeeeaaaaaaaak!!!!!

@parliament:
1st THANK's for so much work. Actually the Vendor should do this, but they didn't even reply to my request jet.
2nd So far I was already, the main problem is the refill, of how to get the plug off without broken nails.
Well, solved that with my (not sharp anymore) pocket knife.
3rd Flooding: More or less solved that by a.) closing one punch hole with a wooden toothpick, and b:) following the rules of how to fill a FOG (by funstore.gr) with that little orange rubber cap put on the bottom during filling, and catching several drops comming out after the Tank is closed again, when You tke the rubber cap off.
During the use all is dry.
After all it's the same priciple than the FOG, only this uses Atty's (510 or 901) instead of cartos. And steel instead of plastic.
I even managed to get the Tank nearly full. Hope You can see the "woodeen plug" in the punched hole.

@Parliament... hopefully you're still leak free. I too had a pre-punched carto that came with my DCT MAP... and those holes on the sides of the carto were HUGE. So I ordered the exact same XL Smok-Tech cartos from Mad Vapes that were not punched to see if my atty flooding/leaking issues were indeed due to the huge pre-punched holes in the carto that came with the tank.

So I put the new non-punched carto in the tank and filled it up... just to verify that the o-rings were not leaking around the carto. Everything checked ok after 15-20min - didn't lose a single drop of juice. Then I drained the juice out, removed the carto and went out to my shop to drill (not punch) 2 tiny holes into the side of the carto with my Dremel. The holes I drilled are probably the size of a pin head if not smaller - just barely large enough to let juice in very slowly. I figured smaller holes would greatly reduce the fast wicking of juice into the carto and eliminate the flooding.

Success! I put it all back together, refilled it, let it stand for 20min... and no leaks! In the 20min I let it stand I could see tiny bubbles coming out of the pin holes I drilled so I knew the carto was filling with juice. Vapes like a freight train now and no more flooding and no more leaks out of the bottom of the carto! Just a nice clean vape.

So it was indeed the carto itself causing my problem. I also think that using a Dremel to carefully drill out tiny holes instead of using a hammer and nail to pound holes in the carto helped as well. The holes are cleaner looking and there is no risk of jarring something loose inside the carto with the force of a hammer.

Many ways to fill these kinds of tanks...

This is the most common and effective way of filling MOST of the carto tanks on the market, including the DCT.

In a nutshell.

At this point. Actually before you've add the liquid.

Pull the carto down (or slide the bottom cap up) until your hole/slit is out of the tank.. The fill with liquid, cap it, then slide the carto back up into the top cap.

@Sierra
Thanks for the great Video selection. Meanwhile I made my peace with the tank! I start to really like it, as it brings out the full aroma of my liquids.
And I found, different to the described, a completely mess-free filling method: from the bottom side. This way the holes are on the upper side when you close the cap, and you press the air out through the hole into the carto, and not liquid.
2 refills without a single drop spilt!!

@Marst

Just curious how you're able to plug one of the holes with a toothpick.. The holes in my cartos from CoV are huge.

Mine where not so big. But try a match, or two tothpicks. (i have round tothpicks)
Good luck
Martin

Edit: I would think about returning the two left ones. They look NOT professional made!

I've never had a leaky Dual Coil on my liquinator, but maybe its because I don't put a nail against a carto on slam it with a hammer? Everyone freaked out about slotting them with a dremel and cut off wheel, but at least there is no wasted juice.

To fill: just take it off your mod, slide the carto down low enough you can drip fill juice around the side of the connector, then push it back flush. Never have taken either of the end caps off, no need too.
