Was recommended by a plumber to never a put valve in a horizontal orientation

if you can help it. Horizontal orientation allows sediment to settle in the
valve and can result in binding or less-than-full closure. Vertical
orientation always results in sediment falling to the bottom of the vertical
run.

That's just silly. If there's enough sediment in your water for that to be a
concern, you should be filtering it where it enters the house.
Got any Iron pipe in your house?

Actually, no. All the supply lines are copper; the drains are copper and
plastic. I've had homes with steel pipe, though -- and never, ever saw a
problem with sediment causing a valve to bind.
