Will i be okay to run ro?

[john henry]

I made a RO for this year. I have 2 4x40's in series. I performed the new membrane "rinse" several weeks ago with good clean well water. I want to use the RO today for the first time with sap. Will it be okay to use since it has sat for a few weeks or do I need to rinse it again before using?

I would give it a quick rinse, maybe not the full treatment

Me too. I would run at least 20 minutes worth of good soft well water, then save the permeate portion and run that thru. Then start running sap thru.
I never let my RO go for more than 3 days without running a quick rinse like that before running sap.

Thanks so much for the quick replies!!! I will follow your advice! Don't want to impart bad flavor to my first batch...
