Burst Pipe Repair in Whitby

A burst pipe is two problems at once: water where it should not be, and a cause that will repeat if it is ignored. We stop the first and find the second.

Kit on the van, and the method

  1. Pipe cutters for copper, PEX and galvanized
  2. Torch, flux and lead-free solder
  3. Crimp and expansion tools for PEX
  4. Pressure gauge and moisture meter

Before we leave: Pressure-hold the repaired run and watch the gauge before walls close.

First, shut the water off

Shut the main valve first. Cannot find it? our field note on the main water shut-off walks through the usual locations in Whitby homes. Turn off power to any wet area, then open a low faucet to drain pressure from the lines.

Why pipes split

Most burst pipes we see in Durham Region follow a cold snap. Water freezes inside a pipe, the ice plug traps the water behind it, and pressure builds between the ice and the closed fixture until the pipe gives. The split often appears away from the frozen spot, which is why the leak shows up only after things warm and the ice melts.

Not every burst is weather-related. Other causes include:

  • Pinhole corrosion in older copper, especially on hot lines.
  • Failed push-fit or compression fittings.
  • Supply hoses to washers and toilets that have aged and cracked.
  • High static pressure where a pressure-reducing valve has failed.
  • Pipes nicked by a drywall screw or nail during a renovation.

Hose bibs left connected through the winter are a frequent Whitby case. The interior portion of a frost-free bib freezes when a hose traps water in it.

Temporary measures

A repair clamp or a push-fit cap can hold a line for a short time and let you restore water to the rest of the house. Those fixes are meant to last until a proper repair, not indefinitely. Keep the damaged area visible, put a bucket under it, and avoid closing up any wall.

Field note. Photograph the damage and the pipe before cleanup. Insurers usually want to see the cause as well as the result.

Permanent fix

The split length comes out along with a margin of good pipe each side, and we splice in copper or PEX to match the run. After that we work out the cause. A pipe on an exterior wall may need insulation, rerouting toward the warm side, or a heat cable. A corroded line may point to wider trouble, in which case repiping becomes a fair conversation. A failed pressure reducer gets replaced and the system pressure checked.

If ice is still present elsewhere, frozen pipe thawing comes first, because a second split may be waiting. Where water reached the basement floor, our basement flooding page explains next steps.

After the repair

Wet drywall, insulation and flooring need drying within a day or two to limit mould. Run fans and a dehumidifier, open cabinets under affected sinks, and pull back carpet where it soaked through. Larger losses call for a restoration company, which your insurer can usually arrange. Before closing any wall, we pressurise the repaired line and watch the joints so nothing gets sealed in with a slow drip behind it.

Asked on the phone

Should I turn the heat up after a pipe bursts?

Keep the house warm, but shut the water off first. Thawing a frozen line with the water on can cause a second leak when the ice clears.

Is thawing with a hair dryer all right?

Yes, warm air on a pipe you can see is fine. Never use an open flame.

Will insurance cover a burst pipe?

Coverage varies by policy. Phone your insurance company right away, photograph everything and hang on to the cut-out piece.
