So I cleaned the stupid tank, put the stupid blue o-rings and the stupid huge coil it came with back in, boxed it up and have it ready to go back to where it came from.

But I haven't heard back from the stupid vendor yet which means it won't be until Monday or Tuesday at least before I have to send it off.

& I had all this yard work to do today but it kept raining on me so I finally quit and went back indoors, and this stupid tank just kept whispering to me from across the room: "Oh common, (for some reason mine has a slight latino accent, think Andy from Cougar Town) try me again. You know I'm fun to build on, and I taste sooo good..."

So I finally caved, made another stupid shim to put underneath the stupid center pin so it'll connect to my Evic VT, build a nice 0,46Ohm coil out of twisted 28g titanium and put a stupid amount of Native Wicks cotton in there but made sure it didn't protrude enough to get between the housing and o-ring.

The o-ring I replaced is looking pretty beat up but it's still hanging in there, but I also found another one when I was packing it back up again so I do still have another spare after all.

Used some tips I got from @MacTechVpr to wear in the wick before use so I get flavor right away (it worked! thanks again Mac!).

Blowing huge tasty clouds again, it does put out a whole lot more vapor & taste then my trusty Toptank.

It better not spit out my tasty home-made-pure-VG banana cream-pie again though! :-x

what were those wick tips for flavor right away?

Just a quickie right now because I really have to get started on dinner, but it's all in this post right here.

I got pretty dizzy from blowing on it while drying out the wick though, so take your time and perhaps use a straw when you get light-headed ;)

:(

It's leaking again.

I've been vaping on it for 3 hours without problems but then juice started seeping through the airflow holes again. I closed the juice flow control and still got to hit it pretty hard for half an hour or so before it started going dry.

So I opened up the juice flow control about 25% for ten minutes or so and now I'm vaping on it again with the juice flow closed off.

It currently isn't leaking but it seems that it's just a matter of time before it'll start again.

Anyone got any thoughts on what might be going wrong perhaps?

I really like how this tank vapes but it just seems so problematic otherwise.

It just HAS TO BE an O-ring problem. Easiest to suspect the bitten one, but I'd carefully inspect every last one in the interior of the chamber.

Honestly, both of my Bachelors are so damn bulletproof that it's almost hard to believe this is happening to you. Make it stop! :(

If you can stop the leaking with the JFC, it sounds like a wicking issue.
But... I like to say "even I can wick this thing, and my RBA/RTA skills are that bad" and I'm loathe to accuse anyone of being worse. ;)

I honestly thought (perhaps still do) that you've simply received a lemon.
Or, as mentioned above, one of the many O-Rings. :(

I still have one o-ring left to replace it with, but just curious, how do your two o-rings below the coil compare to each other. From the start the one below the screws that hold the coil in has been thinner than the one above the screws. Is this suppose to be this way or could that be at fault perhaps?

I only have one good o-ring left so I can't replace both.

edit: just re-posting the pic I took when I took it apart for the first time, but you can probably see that the bottom o-ring doesn't protrude above the threads while the top one does protrude a lot which is probably why it shreds so easily.

Same as @man00ver. I almost can't wrap my head around it. Is your top fill sealing properly?

Top-fill seal seems solid. It also takes a bit of force to swivel the top open so I have no reason to suspect that one.

I'm not a 100% certain about my first build on it, but I'm pretty sure the wicking is just about perfect on this build. Got the coil sitting real low too, if I put it any lower it would short against the deck.

If I got the wicking wrong, wouldn't it start leaking right away?

I've been vaping on it for 3 hours without problems before it started leaking this time. And the first time I tried I had used it for an entire evening without problems but woke up to an emptied chamber in the morning with juice still pouring out of the ariflow holes. This was with the juice control closed.

I won't say this is the problem, but there's an old bottom-air RDA issue that applies here as well.
If any wicking touches the channels under the coil(s), a combination of surface tension and capillary action will create a slow river of juice out the air intakes.

I'm always cautious about how low I set my coils.

I've read about that somewhere in this thread before I received mine so I made sure that my wick didn't touch those holes. But I'll keep an eye on it when I open it up to inspect it in case it moved somehow, thanks.

Alright guys, I think I found the problem, it was me being dumb and careless!

I just took it apart again to insert my last o-ring and upon inspection it turned out the loose o-ring in the chimney was missing!

It's still in place in that picture I posted above ^ but I did clean the tank before first use so it's likely it was already missing when I first tried it. Checked the sink but it's been a few days ago so I couldn't find it, it must have gone down the drain.

The spare o-ring I had left seemed to fit in there so I stuck in in there and carefully put it back together again and filled it back up. I'm keeping it with the juice flow control wide open now so I should find out quickly if it's still leaking.

So thanks to everyone that tried to help me, and apologies for wasting your time. I'll keep you guys posted!

ps: does anyone know where to get more o-rings in case my local vendor can't supply me with them?

No waste of time... there's a lot of damn rings and gaskets in modern tanks.
I think we're all holding our breath still. Keep us posted.

The no spare top gasket issue caused some to light a fire under EHPro and their main vendor Eciggity. Hopefully they'll make them all available. Especially those around the deck.

i use a pretty long 3.5 - 4 mm coil, where the legs go straight down to the post holes. once i wick it, i cut the wick flush, but at a bit of an angle so it's longer at the bottom. then i push it in flush so that no cotton protrudes past the outside of the deck. maybe your wick is getting caught when you adjust juice flow?

It's still dry, no sign of fluid when I shine my flashlight through the air holes neither :banana:

In all fairness though, it is a bit of a fiddly design with that loose o-ring in there and I still haven't solved the problem with it eating the top o-ring above the scrub-screws neither (I think that's what those are called anyway?).

I didn't want to sand the threads yet since I might still have to send it in and get a replacement, plus I'm not touching that o-ring until I have something to replace it with.

But I do like the taste and vapor production of this tank so if it works without leaking I would like to keep using it until a better single coil design hits the market.

At least I'm looking forward again to receive the Nano version that I won. If anything it'll at least supply me with another set of desperately needed o-rings, lol

I think you may have missed my before-last post up there^, but I appreciate the suggestion nevertheless

The seal that sits in the chimney, if you noticed, is a flat seal instead of an oring.. And the one under the glass is a flat seal too. Mines never fallen out on me, but I knew about it before I got it so I was aware. It stays in there pretty good for the most part.

So it hasn't been in since the beginning, that is definitely the problem...
