My RODI system stopped making water and I can’t seem to troubleshoot it. I have 100+ psi going into the system and I have water going into the the RO canister no problem. But, I have no permeate coming out of the RO canister. So, replaced the RO membrane with a brand new RO membrane and still no permeate coming out. I even removed the little check valve elbow thinking that the check valve inside the little elbow got stuck. Still, no permeate….what gives? What am I missing?
