While below-freezing temperatures are not that common in Sydney, they do happen – and with below-0 weather comes freezing pipes that could burst. Wondering how pipes burst and what happens when the burst? Find out in this blog now.

Burst Pipes Can Lead To Major Water Damage

What happens when a pipe bursts in your home? Well, pipes aren’t meant to freeze. So as cold weather affects your home and temperatures drop, the water in your pipes can begin to freeze. This usually happens in exterior walls in homes with poor insulation, or exposed pipes in crawl spaces, basements, and other areas without proper insulation.

Ice is less dense than water. So as the water freezes into ice, it expands, blocking the flow of water. This puts great stress on the pipe wall, which may burst. Once frozen pipes burst and thaw out, water leaking from the pipe can cause serious water damage.

What To Do If A Pipe Bursts In Your Home

First, you need to stop the water pipe from causing further damage. Turn off the water in your home using the main water supply shut off to stop the water pressure from growing, and halt the leak.

Then, call a plumber right away to get the pipe fixed, and reduce water damage. Depending on the extent of the leak and its location, you may be able to clean up the water yourself using a mop and towels, and using fans to circulate air and eliminate moisture.

However, it’s usually best to call a professional to clean up larger leaks to prevent mold and ensure that you avoid any serious damage.

Preventing Burst Pipes


How can you stop pipes from freezing? There are a few steps you can take.

  • Warm up the pipe – If you think a particular pipe has frozen but it has not yet burst, you can use a hair dryer to thaw it out and prevent it from bursting.
  • Insulating your pipes – Pipes that are exposed to cold temperatures can be insulated with foam that wraps around them, which helps prevent them from freezing and bursting.
  • Trickle your taps in freezing weather – Leaving a trickle on each of your taps helps keep water flowing through the pipe, preventing it from freezing.
  • Turn up the heat – Consider bumping your thermostat up a few degrees, and don’t turn down your heat at night, as this is when the coldest temperatures occur, and this can lead to freezing of your pipes
  • Keep cabinet doors open – Opening the doors of kitchen and bathroom cabinets that have pipes in them helps circulate warm air, keeping them from freezing.
