Poly B piping, short for polybutylene, was once the go-to material for residential plumbing installations in Calgary and across Canada from the late 1970s through the 1990s. It was widely used because it was inexpensive and easy to install.
However, over the years, it became clear that Poly B pipes are prone to failure. The result? Many homeowners are now facing leaks, water damage, and costly repairs. At Aquality Plumbing & Heating, we understand how serious Poly B pipe problems can be.
That’s why replacing these outdated systems is one of the most important services we provide to Calgary homeowners. In this blog, we’ll explain how we manage Poly B pipe replacements, what you can expect during the process, and why acting sooner rather than later is essential.
Why Poly B Pipes Need to Be Replaced In Calgary
Poly B pipes degrade over time, especially when exposed to heat, high chlorine levels in municipal water, or high pressure.
The fittings can also become brittle, leading to small cracks or sudden pipe bursts. Many insurance companies are reluctant to provide coverage to homes with Poly B, and some refuse entirely unless a full replacement is completed.
We aim to help homeowners eliminate this risk with long-lasting, modern piping materials like PEX or copper. We’ve completed countless Poly B pipe replacement projects across Calgary and bring that experience to every job we take on.
How We Identify Poly B in Your Calgary Home
The first step in the replacement process is a thorough inspection. We look for signs of Poly B pipe throughout your home, especially in basements, utility rooms, crawl spaces, and areas near your water heater or manifold. Poly B is typically grey, flexible plastic tubing. It may have markings such as “PB2110.”
If you’re unsure whether your home has Poly B, we’re happy to perform a full plumbing assessment. Once we confirm its presence, we’ll provide a detailed replacement plan and help you understand the steps involved.
Our Step-by-Step Poly B Pipe Replacement Process
Replacing Poly B piping is a complex job, but our team has developed an efficient and minimally disruptive process:
Assessment and Planning
We start by creating a plan tailored to your home’s layout. We map out where the current Poly B runs, identify access points, and determine the best way to install the new pipes with minimal damage to walls, floors, or ceilings.
Protecting Your Calgary Home
Before beginning the replacement, we take every precaution to protect your home. That includes covering floors, moving furniture if necessary, and using dust barriers to clean work areas.
Pipe Removal and Replacement
We systematically remove the old Poly B pipes and replace them with modern PEX or copper piping. PEX is our preferred option for many homeowners due to its flexibility, resistance to freezing, and cost-effectiveness. In some situations, we recommend copper if there are specific performance or aesthetic preferences.
Wall and Surface Repairs
Poly B replacement often involves opening drywall or other surfaces to access plumbing lines. 
Once the new piping is installed, we patch, repair, and restore those areas. If you already have contractors in mind for this part, we’re happy to coordinate with them, or we can recommend trusted professionals.
Testing and Final Inspection
We always test the new piping system thoroughly before finishing a project. Our team checks for leaks, ensures proper water pressure, and confirms that every fixture functions as it should. Only after a full inspection do we consider the job complete.
How Long Does It Take?
The length of time required depends on the size of your home and how accessible your plumbing is. A full Poly B replacement takes between 3 and 5 days. We do our best to work quickly without sacrificing quality and always aim to minimize disruption to your daily routine.
