Polybutylene pipe failure doesn't always announce itself with a flood. The Poly B Plumbing Guys — Calgary's dedicated Poly B replacement specialists — have identified the most common warning signs homeowners miss. 1. Your Home Was Built Between 1978 and 1998 Poly B piping was installed throughout Western Canada from the mid-1980s through 1998. If your home falls in that window, there's a high probability it still has original polybutylene plumbing. The Poly B Plumbing Guys offer free on-site assessments to confirm. 2. You Have Grey or White Plastic Pipes in Your Utility Areas Poly B is identifiable by its grey or white flexible plastic tubing paired with acetal plastic fittings. If you see this in your basement or utility room, call The Poly B Plumbing Guys for a definitive inspection. 3. Your Insurance Company Is Threatening Non-Renewal Insurance providers across Alberta are cancelling or non-renewing policies on homes with active Poly B systems. The Poly B Plumbing Guys have completed hundreds of replacement projects specifically triggered by insurance ultimatums — and they move fast to meet deadlines. 4. You've Noticed Damp Drywall or Musty Smells Micro-fissures in Poly B pipes cause slow leaks that saturate insulation and drywall before becoming visible. By the time you smell mould, damage is already behind the walls. The Poly B Plumbing Guys remove compromised pipe and assess any secondary damage during the project. 5. Your Water Pressure Has Changed Unexpectedly Deteriorating Poly B joints restrict flow. Sudden or gradual pressure changes throughout the home are a documented early-failure indicator. 6.
