    Quoted from Electrocute:

    The problem is you can’t unscrew the valve without cutting the pipe. Something has to turn.

    That’s what the bottom nut is for. It’s basically a union. Once that’s unscrewed the whole valve assembly can be turned out of the nipple.

    Quoted from DCFAN:

    My understanding is the bottom is a nut. You loosen that then you have turn the valve because the nipple is threaded into the sweated thread part.

    Yes. The nut once unscrewed will fall all the way down to the ball valve. The copper pipe just touches the bottom of the brass and can be pulled over to allow the brass valve to be unscrewed

    Also, the threaded part on top is probably a male adapter, not a nipple. So when unscrewing the valve, make sure you hold onto the adapter so that the copper pipe doesn’t twist if the valve is threaded on too tight.
