    Simple question I hope, I've a copper overflow pipe that comes out through a wooden panel and I was going to put a bit of lead flashing over it and then thought I wonder if they react together. Normally I wouldn't think twice about copper and lead side by side but we live right by the sea and everything gets covered in salt spray and I wondered if that makes any difference?

    I believe the lead if in contact with copper would be subjected to corrosion between theses metals, at what rate? I couldnt say off the top of my head.

    Not sure what this panel is like? but maybe you could just seal it up with some suitable sealant??

    Coppor onto lead pipes do not react,But Coppor onto Iron does.
    Lead was always joiled onto coppor pipes before it joiled appliance ie. taps and toilets for over 100 years by doing a wiped soldered ball joint, I havent had to do one for many a year, any plumbers left out there who still has that old skill?
    Any way don't mind my rambeling, coppor onto lead is ok, even by the sea.
