What this means for you: Denver is about middle-of-the-pack (#7 of 11 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.

Galvanized steel pipe corrosion and cast iron drain-line issues
A large share of this area's homes predate 1960, when galvanized steel supply pipe and cast iron drain lines were standard. Galvanized pipe corrodes from the inside over 40-50 years, gradually restricting water flow and eventually leaking at joints; cast iron drain lines crack and are prone to root intrusion at the same age. If a home this old hasn't been repiped, these are the failure modes actually driven by the pipe material itself, not just general wear.
This is general guidance based on Denver'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.
