Don't be the one that shuts the city water valve that feeds the water to
your house. My plumber refused because the potential for trouble is always
there---and was he right! City came down and the long shaft to the valve
broke off. They had to dig up the street down to the valve, replace the shut
off handle. Fill it all in and then had to re-hot top the dug up section.
All in all--let a plumber do it.
It's a cheap (junk) gate valve with a snapped stem, you were lucky it
lasted that long. Call a real plumber and have it replaced with a full
port ball valve. From what I've read here I wouldn't suggest doing it
yourself. Your other option is to move.
You already have loads of input, mostly good.
Definitely get the water company to shut the street valve.
What I would add is to hacksaw the upper elbow thru its middle so that
end is free, then unsolder the bottom end of the valve. The heat will
boil the water out (careful of boiling spatters). Then unsolder the
rest of the elbow, clean both ends, and sweat a new valve and elbow into
place. You may need to add a short bit of pipe between the valve and
elbow (if the new valve is smaller) or cut a bit off the top of the
vertical pipe (if the new valve is larger).
