Ok here's another question.I have a 24gpd 3-stage RO unit.I would like to add a DI to it.Can I use the tap water purifier on the output of my RO unit or will there be too much back pressure put on the RO membrane?BTW it is a TFC membrane.
I've been running my 60gpd Sectrapure the way you describe for the past two years and am extremely happy with it. I usually replace the TWP cartridge every 4-6 months or so (that's how long it takes for the color to change completely). Hope that helps!
