Polybutylene "gray flex" supply lines were installed in a small subset of Blaine homes built between roughly 1985 and 1996 — most often in the original Aquatore and central Blaine 1980s walkouts and a handful of early Lakes-area builds.
We document polybutylene plumbing with annotated photos, measurements where applicable, and a written priority recommendation routed by safety priority. When the finding warrants it, we refer you to a Minnesota-licensed specialist for repair -- never to anyone we have a financial relationship with.
Defects discovered during inspection are leverage. Whether you negotiate a credit, request a repair, or walk away, our reports give you and your agent the documentation needed to move forward with clarity. Report in 24 Hours turnaround means you keep your inspection contingency window intact.
Type your address, get a real number, book your Blaine inspection on the spot. No callbacks. No sales pressure.
The material is recall-class: it fails at the brass or acetal fittings without warning, sometimes catastrophically. Class-action settlements have long since paid out, but the material is still in walls. We identify polybutylene by the gray color, distinctive crimp fittings (no brand stamp), and the dull plastic feel — not to be confused with PEX. If found, we strongly recommend full re-pipe to PEX or copper before close. Most insurance carriers will not renew a homeowners policy on a home with active polybutylene.
