Is your wick touching the center air hole at all? Try posting a pic of your build.
Thanks Ricks! I
Thanks Ricks! I had to go out of town and I left the Dvarw at home, so I can't post pictures now. I'll post photos when I am home again. My current theory is that the top of the chamber isn't sealing properly because it is not level -- one side is pushed down further into the chamber than the other. I can pull the top of the chamber completely off, but when I put it back, I can't make it level. I tried to remove the o-ring on the top of the chamber to install a new one, but I can't get the o-ring off.
I posted these pics in the rayon thread to help. A couple people were having issues, so I did these to help. They were doing the bunny ear thing and sliding the jc ring over, then cutting and thinning wicks...
I have used the bunny ears method with no issues at all.
With rayon wicks? I never really tried the bunny method, so not sure how much difference there is, but there were 2 new rayon users that were trying to thin out the tails after the jc ring was on, which would be a bit of a pain. Whether you can thin and trim tails first, then bunny them, probably , but they were having issues, so imo, this might help them.....overall, I dont people have issues bending the wicks upwards, then snapping on ring, I justthink this method is a tad bit easier, but what ever your use to is perhaps the best.
Oh no not with rayon, with cotton. I didn't think rayon would be so much different.
My usual way

Rayon is a lot better. Lasts longer and won't burn as easily as cottons.
Leaks mean you don’t have enough wicking.
I am the guy who on FT forum was once writing a thread how my Dvarw leaked like crazy and is very finicky with wicking - this was when I just got it and was not familiar with it. I came from Kayfuns.
It took me a lots of troubleshooting and experimenting with wicking to find what was wrong: The key is that the Dvarw needs more wick than I used with the Kayfuns. (With the Kayfuns, I always stripped off top and bottom layer of cotton after I cut the piece). With the Dvarw, I just cut my strips from my cotton sheets (about 0.7cm wide or so) but I do NOT strip, so I use more cotton. (If it's too thick in the beginning, twist the cotton so it fits through).
And then wick just like they show in the pics above, exactly like benley73 does. Make sure to tuck it down at the two ends, and make sure the holes on the side are COVERED. (I have reason to believe that the Dvarw V1 with the smaller, round holes may be less prone to possible leaking as the holes are smaller). But anyway, if you do it like that, it will not leak.
So yes, TLDR: Use MORE cotton. But also don't make the ends too long, and also not too short. Again, like benley74 or Tony does above, it's perfect.
(I am usually tucking straight down, but you can also fan it out a bit so that there are two "half moons" like Tony has it, essentially covering the two halves with cotton)
Diver, that's the same way I do my Dvarw's. Works great with Tidi rayon or cotton. This way is just easier for me.
Simple 26g 316L 2.5 ID at 0.5Ω.
I bought a few of the wider JC pieces to swap out with the smaller ones. I merely wanted to check them out. Feels like a more saturated vape to me, very nice. I like.
The wider ones work great and it doesn't matter what ratio juice I use. I DIY and make 50/50, 70/30 and 80/20 (VG/PG). The Dvarw handles them all flawlessly. I mostly vape 50/50 and have never had any problems in any of my Dvarw's. Although I didn't have any issues using the smaller hole JC with any ratio of juice either.
138 grams dry. Used to be a gold plated dvarw but the plating sucks on these. Get a stainless one!
Used to run a stock tank on a pico. Was HEAVY. Running the bell cap takes a lot of weight off and keeps the heat from coming up to the drip tip. But going to the plastic Tesla mod I found overheating to be an issue during chain vaping. An aluminum heatsink solved that issue with only a 5g weight penalty.
Finally going to try this out. I haven't bought any clones since the original Aqua's a few year ago, but have been disappointed with many original RTA's I've purchased. I prefer a loose MTL. The only thing that's been reliable have been the Bellus tanks in single coil mode. Just been searching for a dedicated single coil tank, and have been disappointed by too many. Either by leaking or juice capacity.
So back to trying a clone. Was interested in the original when I first saw the original reviews. Coppervape seems to have a good reputation in the clone market. Now, just waiting for FT to ship.
I've been having a hard time with the Bellus doing dual coils. Someone else mentioned this to so I'll just try doing single coils this time (have the adapter... never been used)
Forgive me if this has been asked, but has anyone run a Dvarw without an AFC insert installed at all?
I'm relatively happy with the 2.5mm but was curious - was it a leaky mess or did it work ok?
Still waiting on China. Tracking has been silent and stuck on Origin facility is preparing shipment. For 2 weeks. Kinda hoping it'll just show up.
I should have them this week. Only took a month, but it finally reached Chicago. Will be fun trying out the air inserts I ordered as well.
Finally received my Dvarw(s) by Coppervape from Fasttech. Took nearly a full month, but they were worth the wait. The vape quality is outstanding.
Easy to build and wick, and using the additional 2.5mm air insert, the draw is what I like these days. The machining is good for a clone (no crunchiness or rough spots), and the height if a little less than the UD Bellus that I've been using. The only quibble I have is with the quality of the polycarb tank, which is paper thin. I fractured one while disassembling. Luckily it wasn't enough to kill the unit. After the Chinese New Year, I need to purchase a few spares.
Overall, I'm glad that I came back to this thread and convinced myself to give another clone a chance.
After cleaning up a few more Dvarw tanks this weekend in preparation to build them, I discovered that those fractures in the PC tanks came that way from FT. A few others had them as well. Disappointing, but that is the chance you take buying a RTA that only includes 1 tank piece.
I did manage to purchase replacement tanks from FT before the left on holiday for Chinese New Year. This time I ordered the PEI tanks, hoping they are a bit more durable than the Polycarbonate ones.
I've really been enjoying this Coppervape Dvarw RTA. After using it for a full week, I am totally in love with it.
The RTA is easy to coil and reminds me of the old day of securing a coil, but made easier than, say, the Fogger. And it couldn't be easier to wick. It's very forgiving in regards to the amount of rayon I use. I've set up 6 of them so far with varying amounts of rayon, and none leak but all vape well. The chimney top hasn't stuck during refills like other have posted, and refilling is mess free. No leaks there, either. The flavor has been exceptional, and it has a nice solid throat hit.
Aside from the awesome flavor and TH, the best thing about the Dvarw is that it's conservative on liquid consumption, and not a guzzler like the Siren or others. It's a damn near perfect RTA and I'm loving every minute of using and working with it. In fact, I just ordered a few more.
I've been disappointed in the recent past with many an RTA due to them being tricky or finicky to wick properly; even the Siren was a pain and I ended up wasting liquid. In fact a few RTA's I learned to hate and just wanted to throw them against the wall due to not being able to wick them efficiently.
Finally, I'm laying to rest my old UD Bellus RTAs and going full on with the Coppervape Dvarw.
