ro plumbing help

coralbeauties · Mar 1, 2021

I need some help understanding is my ro unit is plumbed correctly. I have a pinnacle unit and there are 4 lines going into the cap end and one on the other end. In the picture the yellow line is coming from the pump. The blue line that is in the same fitting location as the yellow line is running through the auto shutoff valve then to the other side of the membrane housing. the inside line is a black like which is currently the rejection line. There is a blue line that appears to be in the same port as the black rejection line is running to the di resin filter. I am trying to understand what each fitting ports are for. If you are able to help out that would be great.
thanks
Jeff

mine is actually just one chamber and has 4 lines in the end of the screw on cap and one line on the other side. This is a newer model of mine but looks to be the same unit. Havent had any luck finding a manual on it yet.
thanks

any ideas? I am pretty sure this is a re circulation type of unit to reduce water usage.

I would guess that this has been discontinued. Most likely because its a 35gpd unit. Where is that yellow tube coming from? You may be able to email Seachem and get a manual.
