You will find many conflicting opinions on this subject.
I believe that you should never run a watermaker at pressure above the Filmtec rating, but more importantly, never above the production rating. For instance, if your watermaker is rated at 160 because the two membranes are rated at 80 liters/hour, never run it producing more than 160. Check the flow glass and adjust the pressure to produce 160 even if the needle is below the green. Too much flow and/or pressure will fracture membranes.
Now, recycling product water: I have never done this, but the physics of RO membranes tells me that it will likely require less pressure to get 160 liters/hour.
