Need ID for RO lines

[Abso]

I am sure about the water inlet line but not sure which is waste water and which is the RO water for tank.
Is the drawing correct?

[Briankook]

Yes that is correct. The waste water line is always "offset." The product water is in the center.

For what it's worth, you should have something like this: http://www.spectrapure.com/St_quality_p5.htm

That way you will know when you need to replace your filters.

What is the use of the thing on the waste water line?
Can i remove it? It is leaking water sometimes.

That's the flow restrictor. You need that or you won't get any output water.
