Sorry missed your post, the best place is after your filter set before the RO membrane. This is the place where your going to see a pressure drop due to a filter clog and it is also going to tell you the pressure going into the membrane. Filmtec membranes require 50 psi or higher and all other membranes require 60-65 psi.
