Why a check valve for your RO/DI? So I can give you an answer.

Thanks Bob. I'm going out of town for a while and want to keep an auto top off running. The shut off wasn't working...rejected water kept running. Apparently the check valve was broken and the shutoff wouldn't kick on.

I have called a couple of places and aside from buying a 3/4" check valve at made to prevent sprinkler systems backing up I cannot get one before my plane takes off.

The checkvalve is normally at the end of the RO membrane (kent maxxima hi s 60 gpd) to prevent backflow
