Ok guys, I have an issue that has been perplexing me a bit. I'm hoping someone else is having this and has figured out how to remedy it... I have not been able to figure this out yet.

I've been using 3.5Ohm IKV attys, vaping 6V, and a 60VG 40PG juice. I always make sure the atty's are screwed in properly, with the liquid control fully open, and they all seem to seat properly. Now here is my issue (it's more of an annoyance than a major issue) I will fill my tank, and be happily vaping along (I chain vape) and when I get the liquid control adjusted just right, thick vapor, great taste, away I go vaping. Every once in awhile when I set the UFS down (only for a couple of minutes sometimes), the entire tank will drain into the collection cup, sometimes (depending on how full the tank was) some will leak out of the 4 holes under the control ring. Now here is the thing, it doesn't always leak, in fact, that is rare, but it does drain into the collection tank more often. This has happened with multiple attys. I can't figure out what I'm doing, or missing.

Ok here is how I have been running my set up. CR is fully open, juice is open maybe 5/8th turn open (it hits great like this) Now there seems to be a fine line of maybe 1/16th of a turn that it hits amazing, but then if it sits for a couple minutes it drains into the collection tank. When it drains, the draw becomes extremely tight, but with some sucking the majority of the liquid returns to the tank around the atty. Then I'm back to vaping like a choo choo train. If I close the liquid control ever so slightly, I will start getting dry hits. Needless to say I LOVE my UFS, but this little idiosyncracy has me wondering what I'm doing wrong LOL

I don't mean to hijack your thread, but I'm hoping someone might have experienced this same thing

@Rick I haven't had this, but I've read a few posts where it did. I'll see if I can't track a couple down. In the mean time, are you using vaseline on the threads and have you removed the lower O-Ring on the atty connector?

Wylie, I use vaseline on all the threads, all the O rings, I have tried removing the top O-ring on the atty connector, it still did it. I replaced the top O-ring and I have tried removing the bottom O-ring, it still did it. I have used both O rings, and it still does it. LOL. This is why I'm perplexed by it. I can take it apart, clean the UFS parts thouroughly, reapply vaseline (I've tried a small bit, to a generous slathering) and it will still do it LOL. I'm honestly at a complete loss to the root cause.

Yeah, check your airholes, One my GGTS's had some gunk in the holes that was clogging them up when I got it, probably lubricant and dirt from the machining process, or some dried polishing compound.

Wylie, I broke out the calipers and took some measurements on my two Orings while they were seated on the atty connector. the bottom one was several thousandths of an inch larger than the top one, I removed both and placed the larger one in the top position. relubed everything and reassembled. We shall see, so far I don't have to open the liquid control nearly as far as I did before, so maybe the top Oring was slightly out of spec or stretched out a bit. Time will tell. Like I said my problem is very minor, hopefully this might have finally solved it.

Have you tried a different atomiser? I had a similar problem with one of my 510s; the threads on the connector where slightly askew, so there was always a small gap on one side even when the juice control was turned off. Whenever I stopped vaping, this slow leak eventually flooded the collection tank air holes, and if left overnight, the whole tank would end up in the CT.

Same thing happened to me too.

I've tried several atomizers, however they are all from the same batch that I ordered from Ikenvape. Maybe they are all slightly off, Honestly it's about the only thing that I can think is happening. Everything else seems in order. Unfortunately they are also the only atomizers I have right now. I need to order some different atty's from Bruce. It's a shame if that's the fact, I really like the way the IKV HR atty's hit

Easy way to find out if it's the atty......while assembling the UFS, right after you've installed the atty, before you've installed the rest of the tank, close the juice control completely, close the air control, and you take a draw on the atty. You shouldn't be able to draw well if the atty seats well.

Then again, I did find a batch of atties that seats well, but for some reason, the atty leaks the juice by itself

They are seated well, I've tried this and you can't pull on them after they are installed. I'm suspecting that mine are like the batch that you had found.

That batch of atties I had that was leaking juice all by themselves were rather different. The 510 connector was slightly shorter than the EM and Joye atties I use now (maybe about 2 or 3 mm).

I found out it was the atty by closing the air control, and opening the juice control. If all the o-rings are doing their job, and the atty is installed properly, it's gotta be the atty.

I have had a similar problem sometimes after I put a new atty in the UFS. I have to really nurse the liquid control for the first half tank or so. I open it an eighth of a turn - it vapes great - starts to flood - close the liquid and vape from the tank- then repeat. If I leave it sitting for any length of time I have to close off the liquid and the air.

After half a tank of juice, I refill the tank and it stops happening - I even have to set the liquid control pretty close to fully open keep the atty fed, and I can leave the UFS sitting with air and liquid open for hours with no flooding.
