RO System Question

Cass · Jan 26, 2006

Is the reason copper tube should not be used with an RO system to the icemaker due to copper leaching? I only install 1-2 a year and have never tried to find out why.

Yes, but some plumbers still install a copper line from the RO unit to the remote refrigerator location.

RO Permeate is more corrosive, lower pH

Here is something I found on an RO site:

"Most brands of RO system will reduce at least 85-90% of salts in water, so you can assume the water salts concentration would be about 1/9th of the content in the feed water. The aggressiveness of this purified water towards the materials into which it comes in contact is a function of its purity. The better the purity, the more its aggressiveness. Piping after an RO unit should therefore always be non-metallic. RO units will pass all the CO2 that is in the feed water. This means the water will be more corrosive. Don't use copper piping after any (brand of) RO system."

They will also pass all the DO (dissolved oxygen) in the water. Which makes the product water that much more aggressive.
