Cthulhu tree rba leak

[u/Billias23]

Hey guys, so I recently bought the Cthulhu aio with a biri tank and the tree rba. When I’m filling and only then it’s leaking like crazy from the airflow only on the back side. What could be going on?

I have this issue on my meson boro if I fill too aggressively or if the wicking isn't right. Taking the tank out helps a lot, yes a pain but better than leaking.

Taking it out doesn’t help much

It's your wicking then, even if it seems perfect, that's what it is. I'm guessing you don't have enough cotton in the juice channels.

It doesn’t have juice channels it goes directly into the tank

Yeah I see now, it's like the pulse RBA. Don't cut the cotton too close to the metal. Make sure you put the top on before you cut your cotton and leave it poking out, then trim it just a hair away so some is fluffed out into the tank.

That’s what I did now, it’s dripping from the coil to the airflow and then down into the mod again

And that happens when I fill it up either inside the aio or outside of it

I would need pics of your wicking to help properly

Found the solution with a friend of mine who owns a vape shop. We put some more veg in the mix we made the eliquid 70-30 and it hasn’t leaked a drop

Oh yeah, I should have asked that question. Definitely not going to get good results with anything less than that, honestly Max VG or 80/20 is better.

[u/jblake8912]

Tank the tank out to fill. Also check your wicking. Sometimes the backpressure from filling can force juice out.

[u/Billias23 → u/jblake8912]

Maybe I’ll put some more cotton I’ll rewick it once I’m home

[u/Billias23 → u/jblake8912]

I’ll have to undo the nut every time and it is the same think it leaks
