Thanks for the help guys. I have found that constantly blowing, flicking and cleaning the the tank leakage has helped reduce the gurgling and spitting. But I'm having to do this way too often that I'd expect.
Any recommendations for a similar device are welcome. I don't want anything too big.
So same size/smaller than the T22 Pro would be perfect.
Hopefully you'll get it sorted and not have to change. I don't know what size tank the mod will take but you could just consider a different tank as opposed to a replacement kit.
