Hi All,
I am upgrading my single post RO to a double post and just purchased a new SS housing for the 2nd and 2 new membranes, Dow XLE 4040. My question is, do I need to clean these out before my 1st use? should I get some Distilled water and run it through them for a while to flush out any of the manufacturer coatings or chemicals in them etc....

Thanks in advance!
