Complete Poly B Pipe Replacement in Burnaby & Metro Vancouver
Full polybutylene pipe removal and repipe using modern PEX or copper — protecting your home from leaks and insurance headaches.
Poly B pipe replacement in Burnaby is not a project to put off. The grey polybutylene supply lines installed in Lower Mainland homes built between 1978 and 1995 have a documented failure rate that has made them uninsurable under most BC home insurance policies. Our licensed plumbers carry out complete poly B removal and full repipe using PEX-A or copper — from the first inspection through to a finished, paint-ready wall.
Polybutylene pipe (commonly called poly B or poly b piping) degrades in response to the chlorine and oxidants present in Burnaby's municipal water supply. Over time, the pipe walls become brittle and develop hairline cracks, pinhole leaks, or catastrophic failures — often at the acetal plastic fittings before the pipe itself. Because the degradation happens inside the wall, homeowners frequently don't discover a problem until water is already causing significant damage to drywall, insulation, flooring, and structural framing.
Our poly B replacement process starts with a thorough on-site inspection of all accessible polybutylene piping throughout your home. We document every run of poly B, assess the condition of fittings, check for evidence of past leaks or moisture intrusion, and give you a complete picture of the scope before quoting a single dollar. The written quote that follows breaks down everything: the pipe replacement, the access points, the drywall repair, and any permit costs that apply in Burnaby.
Replacement material depends on location and preference. PEX-A (cross-linked polyethylene) is the dominant choice for residential repipes in BC — it's flexible, freeze-resistant, and accepted by every major BC insurer. Copper remains the premium option, particularly valued in high-pressure zones and mechanical rooms. We explain both options clearly and let you decide with full information. Either way, the new supply lines are installed to BC plumbing code, and the completed work is documented for your insurance provider.
We also handle the drywall repair. Most repipe contractors patch the access holes to a rough standard and leave the texturing and priming to someone else. We take the job to completion — patching, taping, floating, matching the existing surface texture, and priming so your walls are ready for paint. You call one company, and the whole job gets done.

Common Questions
Poly B Pipe Replacement FAQ — Burnaby & Metro Vancouver
Everything homeowners ask us about polybutylene pipe replacement, insurance requirements, and what the process involves.
Does poly B piping need to be replaced?
Yes. In British Columbia, poly B has been flagged as a high-risk material by virtually every major home insurer — meaning you either replace it on your schedule, or your insurer forces the issue on theirs. Beyond insurance, the material has a well-documented failure mode: chlorine in municipal water gradually embrittles the pipe walls from the inside out, and the acetal plastic fittings are prone to sudden cracking once they've aged. There's no reliable way to inspect poly B for internal deterioration without cutting it open. If your Burnaby home was built between 1978 and 1995, the pipe is now 30 to 50 years old, well past the point where most plumbing engineers consider it low-risk. The question isn't really whether to replace it. It's whether that happens on your timeline or after a flood.
When was poly-B piping banned in Canada?
Polybutylene pipe was never banned through a single piece of legislation in Canada — it quietly lost its approval in provincial plumbing codes through the late 1990s and early 2000s. The turning point came in the United States, where a $950 million class action settlement in 1995 (Cox v. Shell Oil Co.) effectively ended North American production of polybutylene pipe and fittings. Canadian manufacturers followed as the material was removed from approved-materials lists. The National Plumbing Code of Canada no longer listed polybutylene as an approved supply material by the time of its 2005 edition, and most provincial codes — including BC's — had already removed it before that. So while there's no single ban date, new poly B installations have been code non-compliant in British Columbia since the late 1990s.
Can you sell a house with poly-B piping?
Legally, yes — but you'll pay for it in one form or another. In British Columbia, sellers are required to disclose known material defects, and poly B's documented failure history almost certainly qualifies. Expect any buyer's home inspector to flag it. From there, buyers typically do one of three things: request a price reduction to cover replacement, make replacement a condition of the sale, or walk away when their insurer or lender won't cover the property. Buyers financing the purchase often find that their mortgage lender's insurance requirements include poly B replacement before funding is released. Replacing poly B before listing removes that leverage from buyers entirely, can speed up the sale, and lets you control the cost rather than negotiate it under pressure. In the current Burnaby market, a properly documented poly B replacement is a genuine selling advantage.
What piping can be used instead of polybutylene pipe?
PEX-A (cross-linked polyethylene) is the most widely used replacement material in Burnaby and across Metro Vancouver. It's flexible, highly resistant to freezing, approved by all major BC insurance providers, and its expansion-style fittings create joints that are actually stronger than the pipe itself. Copper is the other proven choice — used in residential plumbing for over a century, universally accepted by insurers and inspectors, and the preferred option in some higher-end or exposed-piping applications. For most Burnaby homes, PEX-A is the practical recommendation because of its flexibility when routing through existing wall cavities during a repipe. Copper makes more sense in specific configurations or where long-term aesthetics matter. PEX-B is a third code-compliant, insurer-accepted option in BC, though it's less flexible than PEX-A and uses a different fitting system. We'll recommend the right material for your specific home and budget when we do the inspection.
What is poly B pipe and why does it need to be replaced?
Poly B (polybutylene) is a grey plastic piping material installed in approximately 700,000 Canadian homes built between 1978 and 1995. It was widely used in Burnaby and throughout Metro Vancouver during this era. Over time, the material degrades when exposed to chlorine in municipal water, causing the pipe walls to become brittle and prone to cracking, pinhole leaks, and sudden bursts. Most home insurers in BC now require poly B replacement as a condition of coverage — or charge significantly higher premiums if it remains in place.
How do I know if my home has poly B plumbing?
Poly B pipe is typically grey or occasionally black, with a dull, plastic appearance. It connects to grey, white, or copper fittings and is often labelled 'PB' followed by a four-digit number on the pipe itself. Common locations include the utility room, under sinks, behind toilets, and in crawl spaces. If your home was built in Burnaby or Metro Vancouver between 1978 and 1995, there's a strong chance it has poly b piping. The only way to know for certain is a professional poly b inspection.
