The only problem is that it didn't hold pressure over night. The bottle was squishy this morning and when I removed the cap, there was no psssssht sound.
I'm going to crank the nut a bit more and give it another shot, but if you'll notice the bottom of the valve stem is completely smooth and round and I'm having a hard time getting any sort of grip on it to tighten it. I can just turn the nut, but that just causes the entire valve stem to turn.
