I'm just setting up my first ever RODI unit.
Got the first 3 stages plumbed in and the kit I bought said to run the water through them for 15 mins to flush them out.
Out of curiosity I tested the TDS.
The TDS out from the first 3 stages (before the RO filter) is exactly the same at 63.
Do they not reduce the TDS at all normally? or is it because my water is fairly low anyway that the next stage should get it down lower.
I still need to add the last few stages and will test again hoping it gets down to 0.
