Why Centennial Homes Are Hitting Plumbing Failure Age
Centennial incorporated in 2001 but most of its housing stock dates to the 1970s-80s. That puts a lot of homes right in the window where original plumbing components are failing — copper supply lines developing pinhole leaks, water heaters rusting out, and main sewer laterals cracking at the joints.
We've worked enough Centennial homes to know the patterns. The neighborhoods along Arapahoe Road tend to have copper supply with cast iron drain stacks. South of Dry Creek, you start seeing more CPVC and ABS plastic. Each material has its own failure mode, and we're equipped for all of them.

Centennial's 1970s-80s Plumbing: What to Expect
The wave of construction that built most of Centennial used copper supply lines and cast iron drain stacks — both solid materials that have a finite life. Copper in this area typically starts showing pinhole leaks around 40-50 years, and cast iron stacks can corrode through at the base where they contact concrete.
We do a lot of cast iron-to-PVC conversions in Centennial. The tell-tale sign is a sewer smell in the basement that you can't trace. Often the cast iron has developed hairline cracks or the oakum-and-lead joints have deteriorated. A camera inspection reveals the exact condition, and we can usually replace a full stack in a day.
Centennial Plumbing FAQs
Why does my Centennial basement smell like sewer?
In 1970s-80s Centennial homes, cast iron drain stacks can develop hairline cracks or joint failures. A sewer camera inspection pinpoints the issue — usually a corroded section that needs replacement with PVC.
Should I repipe or spot-repair copper pinhole leaks?
It depends on how many leaks you've had. One or two in 40 years? Spot repair is fine. Three or more? The system is failing systemically and a full repipe with PEX-A saves money long-term.
Do you install expansion tanks in Centennial?
Yes, and they're required by current code on any closed-loop water system. If your water heater doesn't have one, it's under excess pressure that shortens its life and stresses your supply lines.
