Just a heads up, those bottles aren't really designed to be pressurized, so this might explode. A 2 liter soda bottle would be a better choice for this

I’m aware, this is primarily a test to see if the original bottle will suffice. I’ve had success with tree top bottles at ~15psi. I’m not super happy about the seal (small leak on cap, left). I intend to keep it at around 10psi for the remainder of the fermentation.

15 psi above atmospheric or 15 total psi?

15psi above atmospheric.

It will 100% not withstand that pressure, I bet you could get to maybe 5

I’ll take that as it’s already at 10 and holding just fine.

My money is on the bottom blowing out. Growing up i used to put things like dry ice in plastic bottles and when they would go, bottles like those usually blew out the bottom. Almost in like a star shaped banana peel pattern. Usually launched the bottle too, so beware of that. If it goes, it may move several feet. I would recommend strapping it down.
