Use ball valves.

OK, now that that's out of the way...

I Googled about installing them upside down like in a basement. Saw pros &
cons. Mostly about it promotes sediment collection messing up the
operation. The ones I'm using are 1/2" & 3/4", one hot and one cold. There
are no flow direction arrows on them.

What's the feel from you folks on upside down installation from actual
experience?

To my experience the direction doesn’t matter. Only about five percent
of them close right after several years no matter how you install the
damn things. I hate gate valves.
