Definition of Polybutylene (Poly B) piping
Polybutylene, often abbreviated as Poly B, is a flexible plastic plumbing material that was manufactured between 1978 and 1996. It gained popularity in the residential construction industry due to its cost-effectiveness and ease of installation. Visually, Poly B is typically grey in color and can resemble PEX tubing, though its chemical structure and long-term durability differ significantly.
Timeframe Poly B was used in Calgary homes (1985–1997)
In Calgary, Poly B piping installations became prevalent from approximately 1985 through to 1997. Most new homes built during this period featured Poly B as the primary water supply line material behind walls, ceilings, and under floors. Although legal, its usage began tapering off after systemic issues began appearing in Canadian homes.
Why Poly B was popular among builders
Builders favored Poly B for several reasons: it was less expensive than copper, easier to install due to its flexibility, and significantly lighter than metal piping. It also required fewer connections and fittings, reducing labor costs. However, its susceptibility to leaks, chemical degradation from chlorinated water, and incompatibility with certain fittings eventually led to widespread concern and its phase-out.
Pro Tip: Poly B was commonly installed in Calgary homes during 1985–1997 due to its low cost and ease of installation.
Knowing what’s behind your walls is the first step to making an informed plumbing decision.
How Long Does Poly B Last in Calgary?
Urban Piping highlights the benefits of timely poly b replacement for Calgary homes, showing clear upgrades and potential savings.
Wondering how much time you have before those aging grey pipes hidden behind your walls give out? Understanding the Poly B replacement timeline in Calgary is crucial to avoiding unexpected water damage, inflated water bills, and potentially costly repairs. With our region’s unique weather and municipal water profile, your Poly B pipes may be nearing the end of their usable life.
Average Poly B lifespan: 15–25 years
In general, Poly B plumbing has a lifespan of between 15 to 25 years. However, performance varies widely depending on materials used, installation quality, and local water chemistry. Most Calgary homeowners begin to see problems between 17 to 20 years after installation, with small pinhole leaks being the first sign of failure.
Impact of Calgary’s hard water and temperature shifts
Calgary’s hard water, rich in chlorine and minerals, accelerates the internal deterioration of Poly B. Add to this our extreme temperature swings—from frigid winters to dry summers—and the stress on the piping intensifies. Pipe joints and elbows are especially vulnerable, often degrading prematurely and resulting in hidden leaks inside walls or ceilings.
Visual timeline of deterioration phases
The typical deterioration cycle includes stages such as hairline cracks forming in high-pressure areas, discolouration near fittings, corrosion around clamps, and eventually visible leaks. Each of these phases may take place faster in Calgary homes compared to other regions with milder conditions.
Expert Insight: In many Calgary homes, Poly B begins leaking as early as 17–20 years after installation.
If your home still contains Poly B and it’s over 20 years old, it’s time to start planning a replacement strategy.

Risk factors that accelerate pipe failure
Certain environmental and installation factors can shorten the lifespan of Poly B even further. This includes homes with erratic water pressure, improper use of metal clamps, prolonged exposure to UV light (from improperly stored leftover pipe), and homes located in areas with especially hard or chlorinated water—common in Calgary and surrounding regions. Homeowners should be vigilant about detecting Poly B plumbing in a Calgary home, as early identification can help prevent costly repairs. Regular inspections can reveal signs of deterioration, while understanding the specific risks associated with installation can inform better maintenance practices. Taking proactive measures can significantly extend the longevity of plumbing systems and save residents from unexpected water damage in the future.

PEX vs Copper: Which is best for Calgary homes?
When replacing polybutylene plumbing, most Calgary homeowners opt for PEX piping. It’s flexible, resists freezing temperatures, and is generally more affordable than copper. PEX installations are quicker and require fewer connections, reducing potential leak points. On the other hand, copper offers durability and longevity but comes with a higher upfront cost and is less tolerable to freezing without proper insulation.
Most Calgary homeowners choose PEX for its resilience to freezing temperatures and affordability.
Urban Piping professionals guide clients through material comparisons based on home age, layout, and budget to ensure the best long-term results.
Full-home Poly B replacement process explained
A full repipe typically involves opening walls to access embedded Poly B piping. The process includes shutting off water, removing old piping, installing new PEX or copper lines, and patching drywall. Professionals coordinate every step, including permits and inspections required by Calgary’s building code.
- Day 1: Prep & water shutoff
- Day 2–4: Pipe removal and replacement
- Day 5: Final inspections & patching walls
Urban Piping also follows clean-worksite practices and maintains water access where possible during the project.
How long does a repipe take (typical 3–5 days)?
While timelines vary by home size, most replacements in Calgary take three to five business days from start to finish. Single-level or open-access homes tend to fall on the short end, while larger or multi-level houses may require extra days for thorough drywall restoration and code inspections.
Planning ahead allows homeowners to minimize inconvenience and schedule during off-peak times—Urban Piping even offers rush service for urgent leak cases.

Costs, Insurance, and Real Estate Considerations
Replacing Poly B piping in Calgary isn’t just a plumbing upgrade—it’s a long-term financial decision that impacts home value, insurance coverage, and resale potential. Understanding costs and disclosure rules gives you control over your home’s future marketability and potential savings on premiums.
How much does Poly B replacement cost in Calgary?
The average full-home Poly B replacement in Calgary ranges from $8,000 to $15,000+ depending on house size, pipe accessibility, and chosen materials. PEX piping is typically on the lower end of that scale, while copper increases both material and labor costs.
Urban Piping provides transparent estimates and phased payment options to ensure affordability without cutting corners.
Will my insurance cover leaks or replacement?
While most insurance providers in Alberta do not cover proactive replacement, they may cover damage from a resulting leak. However, insurers increasingly deny coverage or raise premiums for properties with Poly B, due to high failure rates. Some homeowners report non-renewal notices unless replacement is completed.
Urban Piping advises homeowners to review their current policy and consider the long-term risk of inaction.
Selling a house with Poly B – what you must disclose
Homes listed with unreplaced Poly B often face value reductions at sale. Calgary buyers are more aware of Poly B risks, and lenders may require documentation of upgraded piping. By Alberta law, any known material defect like Poly B must be disclosed during sale. Potential buyers are urged to conduct thorough inspections to uncover any issues associated with Poly B plumbing. Understanding Poly B in Hidden Valley is essential for homeowners looking to sell, as it can affect the marketability of their property. Those who have upgraded their plumbing may find their homes more appealing and can often justify a higher asking price.
