Do copper kitchen pipes make tap water taste metallic or add copper to water?
Copper leaches from pipes into soft or acidic water. A carbon filter removes most dissolved copper from tap water.
What's actually in it
The answer to this question depends on conditions: what material, what temperature, how often, and what alternatives you have available.
Research shows that under some conditions this is low risk, and under others, chemical transfer is measurable. Understanding when matters.
