Sometimes you have to sweat in a short length of tubing, and a slip coupler.
Or, a water copper union.

Other times you can unsweat the old valve, and put the new one right there.

Whether it be the sharkbite system. which looks intriguing, or a
standard solder joint, one aspect I haven't found yet is how to
properly cut out and remove the old valve so the new pieces will
slip in properly.

Namely how do you best compensate for the inch where the pieces
will mate without unnecessary tugging on the existing remaining
copper pipe? Or am I being too cautious?

One thing I did verify today is I can easily shut off the
household water supply at the meter. Plus I have a spigot near
the basement steps lower to the ground that will aid in proper
draining of the pipe.


Odds favor I'll be sweating pipe. Now just looking for some hints
to properly cut out and then fit the replacement parts.
Look at http://www.plumbingsupply.com/copper.html#coupling - you
will see with stop and without stop. You want without stop. These guys
are in Chico California but there is no minimum order quantity.

Grainger carries them too.
