Is this well water? I would think after 11 months the flux would be gone. Please see this site it is very informative on presence of copper in your water. http://www.ianr.unl.edu/PUBS/water/g1360.htm
11 months later your copper pipe should have oxidation inside this should keep any leaching of copper into the passing water at a minimum.
