Why Does My Burst Pipes Get Worse During Winter?

Water is unique because it expands as it freezes. This expansion happens inside your plumbing when temperatures drop below freezing. The ice that forms takes up more space than the liquid water did before. This process creates pressure against the walls of your pipes from the inside out.

Metal and plastic pipes are strong, but they are not designed to withstand the extreme force of expanding ice. The pressure builds until the pipe material fails, resulting in a split or a complete rupture. A small, unseen crack can release a large volume of water once the ice blockage melts and flow resumes.

Your first action must be to stop the water flow. Locate your home's main water shutoff valve and turn it off completely. This valve is often found where the water line enters your house, such as in the basement, garage, or near the water meter. Knowing its location before a crisis is crucial.

After shutting off the water, you can turn off electricity to the affected area at the circuit breaker if it's safe to do so. Move any furniture or valuables out of the water if possible. Then, contact local water damage pros to address the flooding and start the drying process to prevent further damage.

• Shut off the main water supply valve immediately.
• Turn off electrical power to the wet area if safe.
• Move furniture and belongings away from standing water.
• Remove excess water with a mop or wet-dry vacuum if you have one.
• Contact local water damage pros for water extraction and drying.
• Document the damage with photos for your insurance records.

Prevention focuses on keeping pipes warm. Insulate pipes in attics, crawl spaces, and garages with foam pipe sleeves. For extremely cold nights, let a trickle of water run from faucets served by vulnerable pipes. Moving water is much harder to freeze. Also, keep cabinet doors under sinks open to allow warm house air to circulate.

Before winter, drain water from outdoor sprinkler lines and swimming pool supply lines. Disconnect and drain garden hoses, and close interior shutoff valves for outdoor faucets. If you plan to be away during cold weather, set your thermostat to at least 55 degrees Fahrenheit. Ask a neighbor to check your home regularly.
