R/O System
 

I just got my R/O system from J&L yesterday and with it I purchased a tds meter. I live in NW Calgary and my normal tap readings were 155 PPM my 5 gal bottled water from COOP was 39 now my first 5 gal jug of R/O water was 3 PPM and my 2nd one was 1PPM. I have been using a carbon water filter for all my tanks and that water read 100 to 115ppm. Just thought I would share.
