Anybody Have Experience Setting Up Ro Filters

It looks like a 4 stage Ro/Di unit. I'm gonna go out on a limb & assume all
The filters & prefilters will need to be replaced. Do you know what GPD the unit is rated at?

Maybe reach out to these guys, they are pretty good dudes & are quick to answer questions. Plus they got some the of the best prices for quality filter replacements. I may almost be cheaper to just buy a new single stage unit but he time you purchase all the replacement filters..

Good luck

what is confusing me the most is the two outputs from one end of the membrane bit on the top.. got two red pipes one with a tap on it.. all i can think is these are the waste pipes, but why two and why the tap, the blue appears to be my ro out and there is another red going into the back in the IN flow which I'm pretty sure is going to be my feed... its all very confusing!

Some ro units have a separate line for back flushing your ro membrane. It allows the membrane to function longer.

This place is on point and is where I get all my supplies and replacement filters and membranes. Stay away from any units that have DI de ionizers. They are for lab quality water for Reef Tanks. Way over kill just get a decent RO

I'll take a stab at it. I have a 4 stage RO unit and it goes, water in-> two filters in line to -> the RO membrane filter where there is a presure bypass valve and the "waste" water exits while the water that passes through goes through one more (carbon) filter and exits as finished RO water. So, it would be easier if I could see the backside but, which ever red line goes to the back of the first {reddish} filter is your water in hookup, then it passes through the middle filter, leaves that filter and goes to the RO filter but the other red line is your waste water, and the water that comes out the top of the RO unit, finally goes through that right filter and exits from the blue line. Thats my guess.
The little valve with the blue parts is the pressure regulator/bypass most likely.

Also, be careful how much you spend on new filters because my portable 4-stage unit, while smaller, only cost me around $65 on amazon and it works great.
