Cold temperatures can cause water pipes to freeze and potentially burst. Taking a few precautions can help protect your plumbing during extreme cold.
Before freezing weather:
- Disconnect and drain outdoor hoses.
- Insulate exposed pipes in unheated areas such as garages and crawl spaces.
- Seal openings that allow cold air to reach exposed plumbing while keeping required furnace and water-heater ventilation clear.
- Locate your home's main water shutoff valve and make sure household members know how to use it.
- During extreme cold, allowing a small amount of water to flow from a faucet may help prevent freezing.
What Should I Do If a Pipe Freezes?
Never use an open flame to thaw a frozen pipe.
A hair dryer on a low-heat setting may be used to gradually warm an accessible frozen pipe. Move the warm air along the pipe rather than concentrating heat in one location.
Be prepared to shut off the water if the pipe has cracked or burst. If you are unsure how to safely thaw a frozen pipe, contact a plumber.
