Should Poly B Pipes Be Replaced?

Yes. Replace Poly B pipes if they leak, show damage, create insurance restrictions or are exposed during a renovation. An intact Poly B system isn’t automatically required to be removed but its age and known failure risk make inspection and replacement planning sensible for many Vancouver homeowners.

Replace Poly B piping when any of these conditions apply:

• A pipe or fitting has leaked.
• A pipe is cracked, brittle or visibly damaged.
• Your insurer requires replacement or limits water damage coverage.
• You are opening walls for a kitchen, bathroom or whole home renovation.
• A home inspection identifies Poly B as a concern during a purchase or sale.
• You have repeated leaks, unexplained water damage or reduced water pressure.
  
  

A full repipe replaces Poly B hot and cold water lines with modern materials such as PEX or copper. The work may require access through walls or ceilings, followed by patching and restoration. The scope depends on the home layout, number of fixtures, accessibility and existing pipe routing.

Existing Poly B pipe is not automatically illegal. Building codes apply to new work and renovations. The National Research Council of Canada advises homeowners and contractors to confirm the codes and local requirements that apply to a specific project.
