Red,
The best place to install them is next to all the quick acting valves in the home, ie - washing machine, fridge line, etc... You could also install some just after the HWT (or HWH) as well. As for orientation, I prefer upright but I believe that they are fine in any orientation. Check the manufacturers directions when installing.
PS - The valve for your toilet is open all the way, right?
