hey traders, well though i bring back this old thread. rebult the old ro. new membrane (mes), new housings (pentair),and fixed many leaks. now she runs great. but i'm alittle short on experience. mabey someone here could make some sents of these numbers? so i started with .5% sap that was 51 deg. then turned up the pessure 350psi.i was getting 3% concentrate. flow meters read 4.5 permeate and 1.25 concentrate. does this look right?
