Ro problem

[Clown boy]

I have just brought a Ro unit off eBay (my first one as I used to buy pre made at shop ) it has 4 pods to it but does anyone know why it has one input (for mains) but two outputs I'm guessing one is the water I use and the other for water to throw away one has blue pipe and one red I guess I keep blue as this one passes though another pod will try put photo up but can someone confirm this thanks to everyone for their help this site is so useful thanks

That would be my guess. See which line has a stronger flow, that would be waste water. On mine the blue RODI and yellow waste. If not sure you can always collect a sample and check TDS.

Yeah your right! Not sure what colour will b waste water though. The water I keep just kind of drips out the pipe and the waste flows out

Cheers will have a look at flow
