My manual for my Kent Max60HiS states that the "Waste to product ratio" is 3:1 and it doesn't have a booster pump, do you think the manual is that far off? I've never filled two buckets at the same time to compare. The Vertex Puratek (100GPD model) claims nearly 1:1 product to waste water ratio, but with it's booster pump will the rejection rate still only be 90%? Does the booster pump have no effect on the membranes rejection rate? Just curious because the Vertex has built in TDS meter, Auto shut off, pressure gauge, etc for a pretty descent price.
