Subtank Mini leaking issues

[Vi-NG]

Hi All,
I have the a Subtank mini (new model) since Mid August and everything worked fine only the first week or so... I love the vaping experience that I got from it, however it leaks from the air-holes.. it happens both with stock coils or rda setup, I use a PG based liquid (70-30). I tried different tips I found on the net but nothing really worked.. any idea what could create the leaking issue?

NOTE: the o-rings seems to be in good shape and, I fill it just before the metal stripe on the chimney.

Thanks in Advance.

in my case, my subtank plus came with the older version rba head with the juice channels, and that works for me.

with the square head coils or the new rba head with the big side holes i get leaking,.

I just bought the white one last weekend and so far no leaking. Using the .5 coil it came with.

Hi @edyle
thanks for sharing your experience with the Subtank, at this point I will buy the old RDA and give it a try.

If your rda's builds on the subtank mini are leaking, then that is probably a wicking issue. I had that problem once or twice, but once I got my building technique down it never happened again. If your stock coils are leaking, then you either have a lack of duds,or the rings missing on the stock coil. Look at the bottom of the stock coil. You should see a whitish/clearish little oring above the threading. Check yo make sure it isn't damaged, or missing. I have hand them fall off before, without even noticing. Other than o rings and wicking problems, the only other possibility is that you have a defective tank and the machining is off. Subtank mini'so are not known to have leaking problems. They have a great reputation in that department actually.

You might want to save your money, because the old style is terrible.Unless you want to be limited to <30 watts. You can get a great vape at that range, but why limit yourself? The new rba is much better in my experience. I have several of both styles. Dry hitting is a major issue with the original style.

Hi @collinsmcrae
I did notice that the base does not screw smoothly on the chimney.. so perhaps it is really a defective tank :-( Anyway, I will try to do a rebuild with more cotton next time and see how it goes. Thanks and have a good one.

Hey bro,
Subtank minis are actually the best for beginners to start with and also a tinsy bit of a rugmuncher. I have two subtanks and i do have leaking problems not from the RBA but from the OCC coils. These coils are a pain because the way they are made makes it confusing when u try to screw them down. I would strongly consider collin's tip there, its true, the o-rings oon the OCC falls off easily and u need to chec if they are in placed NICELY. And when u screw them down, screw them down tightly but not to huge extremes. But make sure its tight. When u screw down ur tanks chimney, make sure that the pyrex glass is snugged and u screew the chimney right down and snugged too. The chimney design for the subtank is a little looosseeyyy sometimes. And sometimes it might also be a dud OCC coil. Other than that, good luck!

Yeah, if you got a defective one I'm sorry to hear that. I've certainly received my fair share of defective products. It just comes with the territory unfortunately, but it is alway's a drag. I found that there was a slight learning curve for myself with the new subtank min rba section. It took a few tries for me to find what wicking methods gave the best results for me. Obviously, with much larger juice ports comes the risk of flooding if under-wicked, but the trade off is worth it because juice flow is much better.
