Burst Pipes in Burnaby: Poly-B, Aging Plumbing & What to Do

Burnaby doesn’t get Prairie-style deep freezes very often, so most burst pipes here aren’t caused by cold. They’re caused by aging plumbing: corroded copper, failing fittings and, in many homes and condos built from the late 1970s to the mid-1990s, Poly-B (polybutylene) pipe. Add the occasional Arctic outflow cold snap, and burst pipes remain one of the most common water damage calls in the city.

Emergency Steps When a Pipe Bursts

1. Shut off the water at the main valve (houses: usually in the basement or crawlspace near the front) or the in-suite valve (condos). In a strata, call the caretaker or the emergency line.
2. Turn off the hot water tank.
3. Cut power to wet areas from a dry spot.
4. Open low taps to drain the lines.
5. Relieve bulging ceilings carefully with a small hole over a bucket.
6. Photograph the burst and the damage, and keep the failed section.
7. Call a plumber and a water damage restoration company in Burnaby.

What Is Poly-B and Why Does It Matter?

Polybutylene, usually grey and stamped “PB2110”, was widely used in BC homes and condos from roughly the late 1970s to the mid-1990s. Over time, it and some of its fittings can become brittle and fail without warning, especially at connections and near hot water tanks. Many insurers now ask about Poly-B and may limit coverage or require replacement.

How to spot Poly-B

• Flexible grey (sometimes blue or black) plastic pipe
• Look near the hot water tank, under sinks and at the main shut-off
• Markings like “PB2110” on the pipe

Other Common Causes of Burst Pipes in Burnaby

• Pinhole leaks in copper, often in older homes, causing slow hidden damage
• Failed compression or push-fit fittings
• High water pressure without a working pressure-reducing valve
• Cold snaps freezing pipes in exterior walls, crawlspaces and carports
• Renovation damage: nails or screws through pipes

Cold Snap Prep (Yes, Even in Burnaby)

• Disconnect hoses and shut off outdoor taps before winter.
• Insulate pipes in crawlspaces, garages and exterior walls.
• Keep the heat on when you travel in winter.
• During an Arctic outflow, open sink cabinets on exterior walls.

Restoration After a Burst Pipe

Water from a burst pipe travels behind walls and through ceilings. We extract, map moisture with thermal imaging, open or vent wall cavities, test older materials for asbestos when demolition is needed, dry with dehumidifiers and air movers, apply antimicrobial, and rebuild. A one-level burst typically costs $5,000–$11,000; see the Burnaby cost guide.

Insurance

A sudden pipe burst is usually covered, but Poly-B, old plumbing and slow leaks can complicate claims. See our BC insurance guide. In a strata, see strata deductibles.
