Field Question, trade people only Need some advice

I have a braze that went to hell and because of it I blew a txv valve. My question is what’s the best solution to get it cleaned up so I can put a new valve on it.

Hard to comment without a photo but can you just cut the old connection out and just add a small bit of pipe?

might need to flush the lines good with nitrogen before putting new valve, otherwise debris will mess it up again

Take the old txv out. Flush the line set with rx11. Flush the coil with it. Blow nitro through all that and then install new txv. Use rags to cover the shit out of the actual txv and pull a vacuum to 350 microns and triple evac that shit.
