Hi friends, I've read several posts of people having issues with their orchids leaking. I want to share a tip that works perfectly everyone with my orchid v4 and I never ever get leaking! When I fill my orchid I flip it upside down and plug the drip tip with my finger. I fill it full then replace the screw. I get a napkin and blow through the drip tip then immediately place the orchid on my device and immediately take a large hit. I blow the vapor back through the drip tip out the holes and wipe any excess liquid if there is any. Then I do this again two more times and the tank is fully pressurized and I get ZERO leaking, no dry hits, and no gurgle. She gives a excellent vape, great flavor and tons of vapor! I usually run my orchid at .6 from 15 to 20 watts.I hope this helps some of you that have issues with leaking. This has worked for me 100% of the time. Best wishes
