Coralife Pure Flo 2 RO/DI

Does anyone have the 50GPD model? If so can you PLEASE post pics of it ASAP I wanna make sure I have this thing up and running right...It has no instructions and the tubes are all the same color, but i'm getting twice as much waste as am Keepable water...thinking the tubes on the RO chamber may be crossed? I just need to see one hooked up from all sides..only pics I can find online are just of front.

 

Waste should be 2 to 1 to 4 to 1 depending on your water supply and the design of the unit. If you have a TDS meter and I suggest you get one if you don't use it to check the water from the slower output. Congrats on getting an ro/di unit.

 

You should have two different color tubes one red and one blue, waste water should be coming out of the red tube.

 

If your getting 2:1, you are doing better than I am. Definitely get a TDS meter.

 

2:1 is not enough and will wear a membrane out very quickly. The waste ratio should be 4:1 as recommended by all the membrane manufacturers.

Pretty much all systems are plumbed the same so look at the photo and drawing at the top of page 6 here:

for how the lines should be routed. Pay close attention to the lines on the membrane housing and note one line is closer to the outside edge than the other on one end, do not get them crossed up.

A TDS meter will tell you if you are correct.
