Is normal plumbing wear in a new home a leak?

New homeowners often mistake normal plumbing materials, residue, and spongy padding around water lines for active water leaks or permanent defects.

“I’m kicking myself about that now. I know there is copper running up and Pex running up to the shower head. But I somehow just noticed the new pipe for the handheld and the top for the shower head look like pieces of galvanized and I’m wondering if that looks like a permanent choice or if that will be switched out when fixtures go in”source ↗

“the last thing I want is questionable plumbing, creating another opportunity for water behind the wall after a rebuild I would literally lose my mind.”source ↗
