Galvanized supply pipe was standard in Portland homes built between 1900 and 1955 — Irvington, Ladd's Addition, Sellwood, Eastmoreland, inner SE and NE. It corrodes from the inside out, so the hot side often goes first while the cold runs hold up for another decade. Polybutylene shows up in homes built between 1978 and 1995, and most insurers in the Portland market now flag it on inspection. The original class-action settlement closed years ago, but some carriers still cover removals as a loss-prevention measure — worth asking yours before you commit either way.
When only part of a system is failing, a partial repipe restores pressure and removes the flagged material without the disruption of a whole-home job. We'll tell you straight if that's the right call for your house — or if you'd just be paying twice.
