Calgary’s winter can be harsh, and the freezing temperatures pose a significant risk to your home’s plumbing system.
Among the most vulnerable are Poly B plumbing pipes, commonly installed in homes built between the late 1970s and mid-1990s.
When exposed to freezing temperatures, these pipes can be prone to cracking and leaks, leading to costly water damage and repairs. As experienced Calgary plumbers, we understand winter’s unique challenges to your plumbing system. Here’s how to protect your Poly B plumbing from freezing and ensure your home stays safe and dry this winter.
Understanding the Risks of Poly B Plumbing in Winter
Polybutylene, or Poly B plumbing, is a plastic material that becomes brittle over time. When the water inside these pipes freezes, it expands, increasing pressure on the fragile material. This can cause cracks, leaks or even burst pipes, leading to extensive water damage.
Replacing Poly B pipes with modern alternatives is the best long-term solution. However, if replacement isn’t an immediate option, you can take steps to minimize the risk of freezing and damage during Calgary’s cold months.
How to Prevent Poly B Pipes from Freezing
Insulate Your Pipes
Proper insulation is one of the simplest and most effective ways to protect your Poly B plumbing. Wrap the pipes in foam pipe insulation, particularly in unheated areas such as basements, crawlspaces, and attics. This helps maintain the water temperature inside the pipes and reduces the risk of freezing.
Keep the Heat On
Maintaining a consistent indoor temperature is essential for preventing frozen pipes. Even if you’re leaving the house for an extended period, set your thermostat to at least 15°C to ensure your plumbing system stays warm.
Seal Drafts and Openings
Cold air can enter your home through gaps and cracks near windows, doors and walls. Seal any openings near your Poly B pipes to prevent cold drafts from reaching them. This is particularly important in areas like basements and garages.
Allow Water to Drip
During extreme cold spells, allow a small trickle of water to flow from taps connected to Poly B plumbing. Moving water is less likely to freeze, and this simple measure can prevent pressure buildup inside the pipes.
Open Cabinet Doors
Pipes located under sinks can freeze if they’re in enclosed spaces. Keep cabinet doors open to allow warm air to circulate the pipes. This is especially useful for kitchen and bathroom sinks on exterior walls.
Monitor the Weather
Stay informed about cold weather advisories and prepare your plumbing system beforehand. If extreme temperatures are forecast, take extra precautions to protect your Poly B plumbing.
What to Do If Your Poly B Pipes Freeze
If you suspect that a Poly B pipe has frozen, act quickly to minimize damage:
- Turn Off the Main Water Supply: This prevents water from flowing into the pipe and causing further damage when it thaws.
- Apply Gentle Heat: Use a hairdryer or a heating pad to warm the frozen section of the pipe slowly. Avoid using open flames, which can damage the pipe and create a fire hazard.
- Call a Professional Plumber: If you cannot locate the frozen section or the pipe has already burst, contact us for immediate assistance.
Consider Replacing Poly B Plumbing
While preventative measures can help protect your Poly B plumbing, replacement is the most reliable solution for long-term peace of mind. Modern plumbing materials like PEX are more durable and better suited to withstand Calgary’s freezing winters.
