What Poly-B Looks Like
- Grey, semi-flexible tubing stamped PB (often PB2110)
- Crimp rings (copper or aluminum) at fittings; some older installs used plastic (acetal) fittings
- Look for stress at tight bends, near hot-water runs, or kinks

Common FAQs
Is Poly-B banned?
It's no longer acceptable in the National Plumbing Code of Canada. Provinces adopt and enforce the code locally.
Will my insurer cover me?
Underwriting varies by carrier and province. Many scrutinize Poly-B; ask your broker before waiving conditions.
If my Marpole home was built in the 1980s or 1990s, does it definitely have poly-B?
No. Builders in the same street chose different materials, and many homes have been partly or fully repiped since. The build year tells you where to look; the pipe itself — grey, stamped PB2110 — is the only confirmation.
