Does Poly B need to be replaced?
The straight answer
No law requires it: codes are not retroactive and existing Poly B is legal to keep. In practice, insurers, age, and resale pressure push most owners toward replacement on their own timeline.
The longer version
Legally, no: plumbing codes are not retroactive, and Alberta’s guidance says previously acceptable products may remain in service. The codes chapter covers that. In practice, three forces set your timeline anyway: your insurer’s position at renewal, the pipe’s age, and what happens when you sell. Replacing on your schedule, before a failure or an ultimatum, is the cheap version of an inevitable job.
