After upgrading to an 8-stage RO system with TDS meters after each stage, I’m getting a lot of insight into what happens with each stage. The biggest take away so far is how long to flush my membranes so that the DI resin isn’t getting blasted with gunk. Looks like it takes about 3-3.5 minutes for the output from the RO membranes to drop from the 50s to 5-7ppm. I have always flushed for 5 minutes based off of a general recommendation but it’s nice seeing the actual numbers.
