Removing the sink seems easy, and closing off the drain doesn't look
that complicated. But clearly I have to securely close off these
supply lines, and make sure the suckers don't leak. Since I can't do
it at source in the basement, I have to install some kind of valves
under the sink to shut it all off. I've never done this or seen it
done.

And here's the rest of the story. It was a plumbing disaster worthy of
your most hearty ribbing. Home Depot guy said you don't cap it, you put
a shut off valve on it and leave the valve shut off. So I tried, without
success, to install the shutoff valve on my now hacked off supply lines.
Each time I turned the water on, it leaked like crazy. And then in what
will not be noted as my finest hour as a plumber, I further tightened one
of the lines only to have the valve fly off.

It's amazing how much water pressure there is in a residential area.

2.5 hours, $11. Failure.

I called a plumber in. He told me that the valves I had been sold would
not work attaching to a poly-B line - if I somehow managed to get them
leak-free, there's no way he's sleep well knowing they were there. Could
come off at any time. He re-cut the line correctly, attached a brass
poly-B to PAX connector, crimping both sides properly with these rings,
using a very expensive crimping tool. Then he connected a proper valve
to the PAX side, crimping again. Repeat on the other supply line.

20 minutes, $132. Success.

I feel like a putz. Take your shots - they are well deserved.
