Okay, I just found this thread on another site.
Check Valve: A check valve is located in the outlet end of the RO membrane housing. The check valve prevents the backward flow or product water from the RO storage tank. A backward flow could rupture the RO membrane.
This is a new one on me. I know I don't have one on my system. Does anyone else?
