What Is Poly B Plumbing and Why Replace It?

We all take pride in our homes, striving to create spaces that are both comfortable and functional. Regardless of the charm and character they exude, there could be a hidden menace lurking beneath the surface: Poly B plumbing.

At A. McKenna Plumbing, we understand the significance of safeguarding your home from the risks associated with outdated plumbing systems.  Let's explore the realm of Poly B pipes, once praised for their affordability but now recognized for their unreliability.

What are Polybutylene Pipes?

Polybutylene pipes, commonly referred to as Poly B pipes, were once popular among homeowners due to their affordability. However, over time, these pipes have become infamous for their tendency to fail unexpectedly. Installed extensively in homes across Ontario from the mid-1970s to the late 1990s, these ageing pipes now pose a significant risk to both your property and peace of mind.

Why the Urgency to Replace Poly B Pipes?

The dangers of Poly B plumbing cannot be ignored. From persistent leaks to the risk of water damage, the consequences of neglecting these ageing pipes can worsen over time. Here's why it's crucial to take action today:

  1. Susceptibility to Failure: Poly B pipes are notorious for their tendency to degrade rapidly, leading to cracks, leaks, and seam separation. Even with copper fittings, these pipes are prone to splitting and fracturing, leaving your home vulnerable to water damage.
  2. Inadequate Water Pressure: As water lines exert pressure on Poly B pipes, they struggle to withstand the force, often resulting in compromised structural integrity and leaks.
  3. Pinhole Leaks: The degradation of the plastic material over time renders Poly B pipes highly susceptible to pinhole leaks, exacerbating the risk of water damage and mould growth.
  4. Chemical Degradation: Exposure to chlorine and other chemicals present in city water can accelerate the deterioration of Poly B pipes, leading to the leeching of harmful substances into your drinking water.

Furthermore, the ban imposed on Poly B pipes in 2005 has made it increasingly challenging for homeowners to secure insurance coverage for plumbing leaks, further underscoring the urgency of replacement.

Identifying Poly B Pipes in Your Home

If you're unsure whether your home harbours Poly B plumbing, there are several telltale signs to look out for:

  • Grey plastic pipes with copper, brass, or plastic fittings.
  • Stamped codes such as "PB2110," "Poly-B Potable," or "PB pipe" on the pipes.
  • Homes built between the mid-1970s and the late 1990s will likely have Poly B plumbing.
  • Visible fittings where plastic pipes are joined with plastic or metal fittings.

Where to Find Poly B Pipes in Your Home

With an estimated ten million homes relying on Poly B plumbing, your home may be at risk. It's important to thoroughly inspect your property. Check water and drain lines under sinks, in utility rooms, basements, and areas connected to hot water tanks, water meters, and shut-off valves.
