I set up my new spectrapure refurbed 90gpd ro/di unit today and was getting about a 2/1 waste to pure ratio so I followed the directions and measured pure in ml for 60sec. I got about 230ml so I removed 2" of the restrictor. This did not fix the problem still getting about a 2/1 ratio. Afriad to cut more, maybe should have cut less? confused....

If your still getting a 2/1 ratio then you have to cut more off. I would only do an ich at a time.
How much waste did you have ?
How much good did you have ?

Ok, I would cut another inch off. You need to get to 4/1
Most likely you will end up around 800 to 200

got the 4/1 ratio dialed in. I have another question. the di chamber looks like it only has water dripping in it and theres only about 1.5" in the bottom of the chamber is this normal?
