A pipe burst. Here is what happens next

The Panther Brief
One useful email a month — seasonal maintenance, real costs, and what to do before you call. No noise. Double opt-in.

A burst pipe is one of the few household failures that goes from fine to serious in minutes. If it has just happened to you, the immediate advice is short: shut the water off, kill power to anything wet, move what water ruins, then call.

What follows is the rest of the sequence, because the plumbing repair is usually the shortest part of it, and people are frequently blindsided by what comes after.

Stage one: stopping it

Everything depends on getting the water off. A fixture valve if the burst is at a fixture; the main shutoff otherwise. In a condo or townhouse where there is no suite shutoff, the building's riser has to be closed, which means the property manager or building manager, and that call should happen immediately and in parallel — not after.

If you cannot find or turn the main, say so when you call. That changes how fast we need to be there and what we bring.

Stage two: the repair

Once the water is off, the pipe itself is usually a contained job. A section is cut out and replaced, joints are remade, the line is pressure-tested and put back into service.

What varies is access. A burst in an exposed basement run is straightforward. A burst inside a finished wall, above a ceiling, or under a slab means opening the assembly first, and the opening is often the larger part of the work.

What also varies is what the burst tells us. A pipe that failed because it froze is a different story from a pipe that failed because it corroded through. The first is about heat and insulation in that spot. The second is about the age and material of the system, and it usually means this pipe is not the only one close to failing. We will tell you which we think it is, and why.

Stage three: drying, which is not optional

This is the stage people underestimate.

Water that has entered drywall, insulation, subfloor and framing does not simply evaporate on its own inside a closed home in a wet climate. It sits. Insulation in particular holds water and dries very slowly, and a wall cavity that stays damp grows mould — which becomes a bigger and more expensive problem than the burst was.

Proper drying means opening the wet assemblies enough to get air into them, removing materials that cannot be dried (wet insulation generally cannot), and running equipment until moisture readings come back to normal. It takes days, not hours, and it is measured rather than guessed.

Restoration companies do this work, and if you are making an insurance claim your insurer will usually have preferred ones. Our job is the plumbing; we will tell you plainly what is wet and what needs to come out, and coordinate so the repair and the drying do not get in each other's way.

Stage four: putting it back

Drywall, paint, flooring, tile, cabinetry — whatever had to be opened. This is the slowest stage and the one most affected by your insurance claim, because scope and approvals drive it.

Insurance, briefly

Most home policies in BC cover sudden and accidental water damage, which is what a burst pipe is. What they typically do not cover is damage from something that was leaking gradually and was not addressed — which is one practical reason not to sit on a slow leak.

Photograph before anything is moved or removed, keep receipts including the emergency call, and tell your insurer early. We are not your insurer or your adjuster and cannot tell you what your policy covers — read it, or ask them directly.

Reducing the odds of the next one

Most Metro Vancouver bursts fall into a few patterns. Pipes in unheated spaces — crawlspaces, garages, exterior walls, attics — during a cold snap. Outdoor taps left connected to a hose over winter. Aging supply lines to appliances, especially braided washing-machine hoses, which have a service life and fail suddenly when they reach it. And older pipe materials reaching the end of what they were going to give you.

The washing machine hoses are the cheapest fix on that list by a distance, and one of the most common causes of a flooded laundry room.

FAQ

Frequently asked questions

What is Poly-B pipe?

Grey plastic water pipe installed in BC homes roughly between 1978 and 1997. Chlorine in municipal water makes it progressively brittle, and it fails at the fittings, usually without warning.

How do I know if I have Poly-B?

Look at the pipe where it comes out of your hot water tank or under a bathroom sink. Grey plastic, roughly garden-hose flexibility, often with grey or copper crimp rings, sometimes stamped PB2110. Send us a photo and we will identify it free.

Is Poly-B banned?

No, and it is not illegal to have. It is a discontinued material that insurers and inspectors treat as a known risk.

Does home insurance cover Poly-B in BC?

Many BC insurers now restrict coverage, increase premiums, or decline to write new policies on homes with it, though practices vary and change. Your own broker is the only reliable answer for your policy.

Will my insurance premium drop after a Poly-B repipe?

Often, but it is your insurer's decision. Ask your broker with our written completion report and permit record in hand — that documentation is what they will want.
