Need plumbing help installing new bath faucets? - help installing american mcgees alice on mac

I'm installing a bathroom shower 3375 by American Standard faucet. The guide shows the source of water from below (basement), but instead of my water pipes from the attic. Can I change the water valve and install the contrary?
