from my research into RO
, it appears there are 2 things to be done to keep production up and rejection minimized
maintain HIGH water pressure, 60 to 80 PSI
maintain luke-warm water, 70 to 80 degrees F
apparently if your water pressure is low, not as much water will get "forced" through the membrane as possible, and will instead bounce off and end up in the waste water line
also, if the water is cold, it makes it more likely to be rejected, my RO
should be here in a few days, I plan on testing to see if running it on a hot+cold mix vs pure cold makes that big of a difference
the thing I'm not 100% on is what my water pressure is ... I believe the building I live in has commerical water pressure, and it's all brand new pipes, so it should be pretty good. I saw a pressure gauge on Drs Foster Smith website, was like $25 - might end up getting that so I know for sure.
