Do you know what is stubbed out of the wall Copper or threaded pipe. I
guessing it's threaded. If it's an older home it's probably Iron pipe. If
it's copper you could take the angle stop apart the nut that remains (
compression fitting) on the pipe should spin easy, then you could find a new
angle stop that fits the old nut. They also make feral puller or you put a
cut in it with hacksaw blade and split it.( don't cut the pipe) If it's iron
pipe if you get it out buy a 3/4" fitting brush clean the inside threads and
replace with a brass nipple. Be careful not to over tighten or you can split
the fitting in the wall.

Anyone have advice on how best to remove old shut-off valves under a
bathroom sink? I've tried the WD-40 thing -- and it worked for all the
fittings -- except for where the valves themselves connect to the pipe
stems coming out of the walls.

Will heating them help?

Thanks!
