Poly B questions, answered straight

No. Poly B was removed from the National Plumbing Code as an accepted material for new work in 2005, but codes aren't retroactive: existing Poly B is legal to keep. You can't install it new, and manufacturers stopped producing it in 1998 anyway. The pressure on Poly B homes comes from age and insurers, not the law. More in the basics chapter.

There's no dependable number, and that's the honest answer. Canadian systems are now 28 to 48 years old, at or past the expected service life, and because the damage happens inside the pipe wall, remaining life can't be judged visually. The failure chapter explains the chemistry.

Yes. Transition fittings joining Poly B to PEX exist, and plumbers use them routinely for emergency repairs, splicing new PEX into a failed section. Understand what that buys you: a working repair today, attached to a system that's still aging everywhere else. Insurers generally won't reinstate or improve coverage on partial fixes, which is why transitions are a stopgap and a full repipe is the durable answer. The replacement chapter covers what that costs.

Meaningfully lower risk, yes. Copper or brass insert fittings, the norm in Alberta installs, avoid the plastic acetal fittings that carry the system's worst failure record. But the pipe between those fittings is the same aging polybutylene, which is why insurers underwrite the pipe's age either way. The Stage 1 vs Stage 2 breakdown has the detail.

Both are flexible plastic supply pipes, which is why they get confused. PEX is a different plastic that doesn't share Poly B's chlorine problem, is accepted by today's code, and is the standard replacement material, with an expected service life of 50 to 100 years. The stamp tells them apart: Poly B reads PB2110. The identification guide shows the difference in photos.

No. Kitec is a plastic-aluminum composite pipe from a later era with its own separate class action. They get lumped together constantly and shouldn't be; the problems, the eras, and the legal history are all different. The basics chapter sorts out the lookalikes.

There was: Canadian settlements with DuPont ($30 million), Shell ($20 million), and Celanese (up to $1 million). Every claims window is closed, the last in 2012, and the famous billion-dollar US settlement never covered Canadian homes at all. The myths chapter has the full record, including the fake Supreme Court story.

Often yes, with conditions. Insurer responses escalate through surcharges, water-damage exclusions, conditional renewals with a deadline, and non-renewal, and positions change by carrier and renewal cycle. If a letter has already arrived, the insurance chapter is the step-by-step.

Not yet. The library covers in-home Poly B supply plumbing, the grey pipe inside your walls. Underground water service lines are a separate topic with different materials and rules, and we'd rather research it properly than guess. It's on the roadmap.

Yes, Poly B homes sell every day. What the pipe changes is disclosure, the buyer's insurance, and the negotiation. The full buying and selling chapters, including the BC and Alberta disclosure rules, are being finalized against the actual court records and publish next. Until then, the insurance chapter covers the coverage side that drives most deals.
