How to Deal With Frozen Pipes
Frozen pipes are a common concern for homeowners during the winter season. Water has a unique property of expanding when it freezes, which places pressure on the container or pipe that holds it. When undrained pipes get frozen due to inclement winter weather, the pressure inside will cause them to break or burst. The U.S. National Insurance Claim Bureau reports that from 2014 to 2015, most water damage claims occurred during the months of January and February, which are normally the two coldest months of the year.
How to Do I Prevent Pipes From Freezing?
- Install a heating cable. To ensure that no water will be frozen inside crawlspace pipes, install electrical heating cables around them.
- Add extra insulation. Water is more likely to freeze in the unheated areas of the home, such as the basement, garage, or outdoor taps, so it is best to add insulation to the water pipes located in these areas. If there are water supply lines in the garage, doors must be kept closed.
- Set the thermostat at the same temperature for both day and night to prevent a costly repair job if pipes freeze or burst.
- Open cabinet doors. Opening kitchen and bathroom cabinet doors will allow warmer air to circulate around uninsulated plumbing, especially if the cabinets are near the home's exterior walls. Secure that harmful chemicals are kept out of children's reach.
- Repair leaks immediately. Before it gets colder, any noticeable crack or leaks in the plumbing must be repaired to prevent leaking water from freezing and bursting right at the cracks, which could result to expensive damages.
- Turn off appliances. Turn off water supply lines and disconnect the hoses from washing machines located in an unheated portion of the home, especially if temperatures are expected to go lower. Before traveling away from home during the winter, turn off the main water valve and set the thermostat to a temperature no lower than 55° F. Disconnect outside water hoses to prevent sitting water in them from freezing.
- Keep water moving. Let a small amount of water trickle from taps and faucets from pipes that are likely to freeze when temperatures get very cold. This helps warm air to circulate and prevents pipes from freezing.
How Do I Thaw a Frozen Pipe?
- Apply heat. Warm the pipe by wrapping it with an electric heating pad or towels soaked in hot water, or by utilizing a portable space heater or a hairdryer. Do not use any open flames. Apply heat until normal water pressure returns. If nothing happens, call a licensed plumber.
- Use a hose. For a large pipe, a garden hose may be run through it; push the hose through until the frozen area is reached. Run hot water through the hose until the ice melts. Be careful with this process since overfilling the hose can cause hot water to back up on your end.
- Inspect exposed pipes for leaks. After thawing frozen pipes, check for leaks or damp patches on ceilings, walls and floors. There still might be a huge amount of pressure left in the pipes after thawing, and it can cause leaks or bursts. If significant damages are noticed, the pipes may have to be completely replaced.
