So do I. You can even turn the ball valves on most PVBs so they face out if in the rare instance you need the PVB to mount the opposite direction. I will occasionally even turn the first BV on a febco 825Y RP so that the TC points down, so that it can drain, if the original installer did not install a drain at this point.
