I’m replacing my gutters, and am considering copper over galvanized metal. Is copper considered toxic for rainwater harvesting?

Hi Allen,
I’m not sure. It is “generally discourage” to use copper but in the few studies I’ve seen there hasn’t been much leaching.

If you’re not drinking the water the quality is much less of a concern, generally speaking.
