Hi Lee Never got below 12 from RO .I wouldn't clean at 12 ?John
My ro needs replacing, I’m currently using it at around 030, been using it for 6 months or more like it. It’s a myth that you need low tds, no one knows what the max tds is before spotting. I’m am going to replace the ro I just havnt got around to it.
