| Re: Flushing an RO membrane? I read that flushing wasn't that effective but I figured it wouldn't hurt. I make around 50 gls a week so thats about 600 gls since I replaced all the filters 3 months ago. Probably no where near what You go thru. I have never gotten below 2ppms. ppms are up to 5 now so it's time. My tap runs at 135 ppm usually. |
