What is Poly B Plumbing?
If your condo was built or renovated between 1985 and 1997 in Calgary, Edmonton, Vancouver, or surrounding areas, there’s a strong chance it contains Poly B plumbing. This gray plastic piping—once hailed as an affordable alternative—now carries serious risks of leaks, degradation, and insurance challenges for Canadian condo owners. Understanding what Poly B (polybutylene piping) is, where it was commonly used, and what to look for is the first step in protecting your home and investment.

History of Poly B Use in Canadian Construction
Poly B piping was widely adopted across Canada from the mid-80s through the late 90s due to its low cost and easy installation. Builders of condo units, particularly in multi-residential buildings in Calgary, Edmonton, and Vancouver, often used Poly B in both interior units and building-wide plumbing systems. However, by the late 1990s, failures became increasingly common—especially at fittings and bends—prompting a nationwide shift away from this material.
“Poly B was widely installed in Canadian homes and condos between 1985 and 1997.”
What Does Poly B Look Like?
Poly B is easy to visually identify once you know what to look for. Most pipes are plastic with a dull gray colour and a diameter usually between ½” to 1″. You’ll often find identifying stamps on the exterior with codes like “PB2110”. Keep in mind—color alone is not enough; black or blue tubes made from different materials exist, so confirming labeling or consulting a professional is essential.

Common Locations in Condo Units
In condos, Poly B piping is frequently found:
- Under bathroom and kitchen sinks
- Behind laundry machines and water heaters
- Inside wall cavities servicing toilets and showers
- In ceiling runs between floors in multi-unit buildings
Shared service lines can make detection and replacement more complex, especially when tied into stacked risers or common property lines managed by strata corporations.
Knowing what’s behind your walls could prevent expensive repair bills.
Why Poly B is a Problem in Condos
Leaking polybutylene plumbing in condos isn’t just a personal issue—it’s a building-wide liability. If your unit still contains Poly B piping, you’re facing elevated risk of sudden pipe bursts, restrictive insurance policies, and costly legal complications related to shared plumbing infrastructure. Fortunately, addressing these concerns early can save your unit and your neighbours thousands in water damage repairs.
Leak Frequency and Water Damage Risks
Poly B’s chemical composition breaks down over time—especially when in contact with heat, chlorine, or high water pressure. In a condo setting, even a minor breach can cascade down multiple floors, resulting in widespread flooding and expensive drywall, flooring, and fixture remediation. Complicating factors like tight pipe routing behind concrete or drywall increase detection time and damage severity. Homeowners and condo associations must be aware of the implications of Poly B plumbing systems to mitigate potential risks. Understanding ‘Poly B water damage coverage explained‘ is crucial for securing adequate insurance and ensuring repairs are covered in the event of a leak or flood. Proactive measures, such as regular inspections and upgrades to more durable piping, can significantly reduce the likelihood of costly water damage.
“Poly B-related water damage is a leading cause of building insurance claims.”
Shared Plumbing and Higher Exposure
Many condos share riser assemblies or trunk lines between units. When Poly B is present in these communal systems, failure in one area compromises multiple homes. As a result, building-wide failures have forced some condo associations in Canada to issue mandatory replacement notices. For residents in Calgary, Edmonton, or Vancouver, this can mean shared costs or temporary relocation during repairs.
“In condos, a single Poly B pipe failure can affect multiple units.”
Real Condo Case Studies
At Urban Piping, we’ve witnessed multi-unit failures in older Calgary high-rises where a single leaking pipe on the 8th floor caused water damage down to the 4th. In Vancouver, one building’s entire insurance policy was threatened until Poly B was removed from the risers. These stories are common—and avoidable with proactive replacement solutions.
Don’t wait for disaster—understand your building’s plumbing before it’s too late.
How to Identify Poly B in Your Condo Unit
Wondering if your condo still has the problematic gray plastic pipes installed decades ago? Knowing how to inspect your unit for Poly B can help you make informed decisions, request early action from property managers, and prepare for eventual replacement. Below are expert-approved tips to identify Poly B plumbing without causing damage to your home.
Signs of Polybutylene Pipe in Walls or Cabinets
Start by examining accessible plumbing fixtures under your kitchen and bathroom sinks. If you spot gray or dull blue-gray tubing that feels slightly flexible instead of rigid like copper or PEX, you may have Poly B. Basements (if you’re in a townhouse-style condo) and laundry rooms are also common areas for pipe visibility, especially near mechanical panels or water heaters.
Visible Markings and Colour Clues
Look for distinct markings stamped on the side of the pipe. The code “PB2110” is the official ASTM designation for Poly B. Although color alone shouldn’t be your only indicator, the gray tone is a strong clue. Unlike PEX, which is often color-coded red or blue, Poly B pipes typically lack this visual distinction and appear uniformly grayish.
“Look for ‘PB2110’ stamped on gray tubing.”
When to Call an Inspector
If you can’t access any visible plumbing or you’re unsure about what you see, it’s time to bring in a certified plumbing inspector. Urban Piping provides non-invasive inspections using specialized tools and extensive experience identifying Poly B in condo units. This is especially important in high-rise units with limited access or for property managers coordinating building-wide assessments.
“Even if you can’t see the pipes, a professional inspection can confirm it.”

Navigating Condo Boards and Strata Approvals
Urban Piping experts present a comprehensive plumbing upgrade proposal for poly b replacement in condo buildings across Calgary, Edmonton, and Vancouver.
If you’re planning to replace polybutylene piping in your condo, it’s crucial to understand how to work with your condo board or strata council for approval. These governing bodies exist to protect shared property interests—but they can slow down your project if you’re not thoroughly prepared. Urban Piping regularly assists homeowners across Calgary, Edmonton, Vancouver, and surrounding areas in navigating the approval path for poly B replacement in Canadian condos.
Getting Permission to Replace Plumbing
Every condo corporation has its own bylaws and guidelines for approving plumbing changes. These usually require:
- Submission of a written request or application
- Proof of licensed and insured contractors
- Detailed scope of work and timelines
- Confirmation that common spaces won’t be disturbed
Pro Tip: Some condo boards ask for architectural drawings or engineering reports for major plumbing overhauls. Urban Piping can assist with preparing these documents as part of your proposal.
Suggested Timelines for Approval
Homeowners should typically expect a 2 to 6 week approval process depending on how often the board meets and the complexity of the work. Proactive communication and providing all requested documents up front help avoid unnecessary delays.

Typical Cost to Replace Poly B in a Condo (Canada)
Urban Piping expert explains poly b replacement costs in Canadian condos, comparing PEX and copper repiping options.
Understanding what you can expect to pay for poly B replacement in a Canadian condo is a key step in budgeting confidently. Whether you’re in a one-bedroom unit in Calgary or a larger multi-bathroom condo in Vancouver, your plumbing upgrade costs can vary widely. Urban Piping breaks it down clearly so you can plan, compare options, and prioritize safety.
Factors That Influence Cost
Several variables affect the cost of replacing polybutylene piping in condos:
- Number of bathrooms and plumbing fixtures
- Accessibility of pipe runs (exposed vs. behind finished surfaces)
- Material choice: PEX piping or copper repiping
- Drywall removal and repair scope
- Location-based labour rates in Calgary, Edmonton, or Vancouver
With Urban Piping, estimates include permits, inspections, plumbing materials, and full cleanup—no surprises or hidden costs.
Cost Range by Unit Size
You can expect the following typical ranges for condo unit sizes in Canada:
- Small (1 bath, 600–900 sqft): $4,000–$6,500
- Medium (2 bath, 900–1,200 sqft): $6,500–$9,000
- Large (2+ bath, over 1,200 sqft): $9,000–$12,000+
“Most Poly B condo replacements in Canada range from $4,000 to $12,000 depending on layout and material.”
Differences Between PEX and Copper Pricing
PEX piping is more budget-friendly, quicker to install, and widely accepted by insurers. Copper repiping costs more due to longer installation time and higher material prices, but can add long-term resale value in some premium condos.
