Hi! Be easy on me as this is my first time posting. I have a procon 101D100F11BD(100 GPH) pump hooked up to a 1/3hp motor. I have two RO membranes(3012 housings)(300 GPD) each attached in parallel. I originally set this system up to run two sets of these in parallel for a total of four membranes(have never tried this though). Just for fun i just hooked up the two membranes but i seem to have so much flow that even if i have my needle valve all the way open i still see 125 psi and the flow is crazy. I take little water out and increase the sugar just a little. Works better if i recirculate. There seems to be a lot of forums with too small of pumps, but wondering if i am doing damage by running too much pump and if i just need to use the other two membranes to take up some of the flow or maybe even more membranes. Thanks in advance for any insight. First year running this ro system.
