Poly B Homeowner Checklist
If your home was built between 1978 and 1995, it may contain Poly B (polybutylene) plumbing. Whether you’ve already confirmed it or you’re still unsure, this checklist will help you take the right steps to protect your home, your insurance coverage, and your long-term investment.
Step 1: Confirm Whether You Have Poly B
Before making any decisions, verify the type of plumbing in your home. Check for:
- Grey plastic water lines (most common colour)
- Stamped markings such as “PB” or “PB2110”
- Plastic fittings at pipe joints
- Home built between 1978–1995
Look in unfinished basements, mechanical rooms, under sinks, or near your hot water tank.
If you’re unsure, schedule a professional inspection to confirm the material accurately.
Step 2: Determine the Age of the Plumbing
If your home still has its original Poly B system from the 1980s or early 1990s, it may now be anywhere from 30 to over 45 years old, which is well past the commonly cited risk threshold. The older the system, the greater the likelihood of internal degradation. Ask yourself:
- Has the plumbing ever been updated?
- Have sections already been replaced?
- Have previous homeowners disclosed any issues?
The older the system, the higher the potential risk of degradation.

Step 3: Check for Warning Signs
Even if your system hasn’t failed, look for early indicators of stress or deterioration, like:
- Small recurring leaks
- Damp spots on ceilings or drywall
- Cracks at fittings
- Discolouration or brittleness in exposed piping
Poly B failure often begins as a slow, seeping leak at fittings, and gradually worsens. While there are often early indicators of a failure, some—particularly mid-pipe ruptures—can occur with little warning.
Step 4: Review Your Insurance Policy
It’s become common for insurance providers to ask if the home contains Poly B plumbing. Contact your insurer and confirm:
- Is Poly-B covered under your policy?
- Are there restrictions related to water damage claims?
- Is replacement required within a certain timeframe?
- Will premiums increase because of it?
Step 5: Consider Your Long-Term Plans
Your next step may depend on what you plan to do with your home. Ask yourself:
- Are you planning to sell in the next few years?
- Are you refinancing or renewing insurance soon?
- Are you comfortable with the risk of potential failure?
- Do you want peace of mind moving forward?
Poly B can become a negotiation issue during home sales. Replacing it proactively can eliminate objections from buyers and insurers.
Step 6: Understand Replacement Costs
Full Poly B replacement in Edmonton typically ranges from $6,000 to $20,000+, depending on home size and layout. Factors that influence cost include:
- Number of bathrooms
- Accessibility of pipes
- Drywall access needs
- Overall home size
Compare that to the potential cost of water damage repairs, which can exceed replacement costs in a single incident.
Step 7: Schedule a Professional Assessment
Even if you’re not ready to replace your system immediately, a professional evaluation provides clarity. A licensed plumber from Always Plumbing & Heating can:
- Confirm piping type
- Assess condition
- Identify high-risk areas
- Provide an accurate replacement estimate
- Offer documentation for insurance purposes
Step 8: Decide on Monitoring vs. Replacement
After reviewing all information, you’ll typically choose one of two paths:
Option 1: Monitor the System
If the system is in good condition and insurance allows it, you may choose to monitor it with regular inspections.
Option 2: Replace Proactively
If the system is aging, insurance requires it, or you want long-term peace of mind, full replacement with modern PEX piping eliminates the uncertainty.
Peace of Mind Starts with Clarity. Contact Always Plumbing & Heating.
Poly B plumbing isn’t automatically an emergency but ignoring it completely can create unnecessary risk. By working through this checklist, you can make a confident, informed decision about your home’s plumbing system.
