So I finally broke down and bought a ro/di unit. The quality of the tap water around here has dropped off abysmally. So I shelled out for a Vertex Puratek 100GPD Deluxe unit, mainly for the low waste (my biggest complaint against RO). However the instructions, which are lacking, say to not use the first 30 minutes of production water and the membrane says 2 hours (before using for drinking water). Does anybody have any experience with this?
