I have a BRS 75 gpd membrane on my rodi. My pressure gauge reads 22 psi. Is this too low? A lot more water is coming out of my waste line now that I put in this new membrane. IIRC my previous membrane was 50 gpd from The Filter Guys. Could that be why I had less waste?

Ideally with the Dow Filmtec 75 GPD membrane you will want around 50 PSI for the best performance. Have you replaced your prefilters recently? Usually a low PSI like that is related to a clogged prefilter like a sediment or carbon block. Do you know how much water you are making exactly in an hour?
