ranked among the metros we have this data for
What this means for you: Phoenix is the lowest of the 11 cities we track for reported plumbing breakdowns, out of the 11 metros this federal survey covers (it doesn't survey every city — see the note below). That's a real, homeowner-reported rate, not an estimate. A breakdown "in the last 3 months" in survey terms usually means a household actually lost working plumbing for hours at a stretch — the kind of failure that's worth having a plumber's contact ready for before it happens, not during.

Polybutylene supply piping, if not already replaced
A meaningful share of homes here were built in the era (roughly 1978-1995) when polybutylene supply piping was widely installed — a gray plastic pipe now well-documented to fail from chlorine-reaction brittleness, and the subject of major class-action settlements. It's not visually obvious from outside the wall, so homes from this era are worth confirming aren't still on original polybutylene lines if a inspection hasn't already ruled it out.
This is general guidance based on Phoenix's real housing-age profile, not a record of repairs actually performed here — the pipe material in any specific home depends on whether it's been repiped since construction, which only an inspection can confirm.
