Help arrived though. I had an area, in the kitchen, I needed opened up. I did help. But didn't do more than a small portion. Beside opening that up, he got the r.o. countertop device going. I couldn't see the markings. Eyes... as you get older. Though, after a bit of fiddling, he figured it out. Then showed me. I can do that, from now on.
I was afraid of twisting the filters off, perhaps damaging the filters or the machine. All good. I ran one pot through, emptied. Ran another through. That is it for today. Tomorrow I am hoping to run two more batches. With the filters being new, they have charcoal running through them, and maybe other chemicals.
