    Can I do this? I have 3/4 copper, then transition to 1/4 adapter to plastic tubing. Then into the reverse osmosis system. Then, go back to copper plumbing (existing) for white refridgerator box.

    The treated output of an RO filter should never go into copper pipe or tube.

    Ro

    IT shouldn't but many new homes here do have a copper line from the sink to the icemaker to supply RO water to it, and have not had problems. At least so far and a lot of them are many, many years old.

    Gary Slusser That's all folks!

    HJ, those people running RO water through copper tubing should seriously have a copper test done on their water. Copper and the human body do not get along well at all; the body suffers.

    There are too many of them to even try to do that.
