Just cut the copper right below the ferrule, then use a Shark Bite 1/4 turn Ball Valve. You never stated how much length you have from the floor or wall for this pipe.
Why not replace only the valve and reuse the old nut and ferrule?
Use a Brass Craft brand 1/4 turn ball valve----
The old ferrule often leaves a dimple in the copper pipe----rendering that bit of pipe unsuited to accept a new ferrule--
That worked great!Most times it's not worth pulling the old ferrule off. If it's that tight, the connection between the ferrule and the pipe is very tight. All you have to do is get the valve to seal against the ferrule. If you're having trouble, clean the brass ferrule up a bit with some emery cloth and try a dab of pipe dope around the mating surfaces.
I may pick one of those up. So far leaving the old nut and ferrule works, but this would be good to have if I run into one that doesn't want to seal and I have to get the sleeve off.i use this all the time

That is a good idea. Those old original construction water lines are crap. Sure enough, I carefully moved one out of the way under the kitchen sink in order to do a minor repair, but the cold water line sprung a leak where the line is soldered to the water bib. Fortuanately I had a spare as I am going from room to rook upgrading things.You can always very lightly spread a thin thin layer of a teflon pipe sealing paste around the existing ferrule getting some in to the wall side between the nut and the ferrule which will lubricate and allow for the joint to be tightened easier without binding and stressing the connection as well as filling any slight imperfections.
I'm wondering how many times you will need to state that to get people to believe it.:laughing: That's what makes it seal.You may be disappointed---if that puller does remove the ferrule---the pipe will(may) be dimpled and will not accept a new one---the compression of the nut presses the ferrule into the pipe,
So if the ferrule doesn't come off with a reasonable amount of pressure, cut it off and cut just behind where the pipe is dimpled. But, if there isn't enough pipe to play with, leave the original.You may be disappointed---if that puller does remove the ferrule---the pipe will(may) be dimpled and will not accept a new one---the compression of the nut presses the ferrule into the pipe,
Stick around for a while. You'll find that as many people that join each day to ask a single question, at least 100% of them don't listen to advice, and just do whatever they want to anyway, even though they asked for advice, simply because they didn't get the answer they wanted to hear.I'm wondering how many times you will need to state that to get people to believe it.:laughing: That's what makes it seal.
Not sure what you are saying. If it is that if I need room to slide the part of the old valve back far enough to expose the ferrule, I thought of that and picked up a few shiny new ones.Round chrome wall flange === escution {eh scuh(like duh)shun(like sun with sh....)}:thumbsup:
