- The part that the City owns runs from the watermain on the street to the property line.
- The part that you own runs from the property line into the home.
- Know where to find your main water shut-off valve and how it works (in case your pipes burst).
- Insulate pipes most prone to freezing, especially near outside walls and in crawl spaces, the attic and garage. This can be done with foam pipe covers available from building supply or home improvement stores.
- Seal air leaks in your home and garage to stop cold air from getting in. Check around windows and doors, electrical wiring, dryer vents and pipes.
- Outdoor faucets are the first to freeze. Unscrew any hoses, turn off the outdoor water supply and let the taps drain.
- If your pipes are prone to freezing, there may be a problem you cannot see. Consider contacting a plumber for advice on how best to protect your home.
- Commercial water customers - protect fire lines by wrapping all lines exposed to the cold.
- Ensure areas that contain indoor water pipes are kept above 8OC, especially near the water meter.
- Keep garage doors closed if there are water supply lines in the garage.
- Open kitchen, bathroom and laundry cabinet doors to allow warm air to circulate around the plumbing.
- If leaving for an extended period of time, turn off the water at the main service valve in the basement and open the taps to drain the water from your plumbing lines. You may also wish to have someone check your home regularly.
- For your own peace of mind, you can choose to run a pencil-thin stream of water to ensure some movement of water in the pipes. However, you will be charged for the water used if you choose this step.
- Run cold water from the lowest point in the house, usually a laundry room sink or tub.
- Ensure the drain is kept clear of debris to prevent overflowing or flooding.
If you turn on your taps and have no water, the pipes in your home may be frozen. Likely places for frozen pipes include against exterior walls or where your water service enters your home through the foundation.
Here are some tips to thaw your pipes yourself, along with precautions to take:
- Do not use a torch with an open flame to thaw pipes, as it creates a fire hazard.
- Ensure you know the location of your master water shut-off valve. If the pipe breaks you will need to immediately shut off the water in your house until the pipe is repaired.
Steps to thaw a frozen pipe
- Turn on a tap in the basement, preferably the cold water faucet in the laundry room.
- Apply heat to the suspected frozen pipe by warming the air around it or applying heat directly to the pipe. You can use an electric heating pad, hair dryer, space heater or warm towel or rag.
- Do not leave electrical devices unattended, or use kerosene or propane heaters, charcoal stoves or any open flame to thaw a frozen pipe.
- Depending on the outside temperature and the extent of freezing within the pipe, the thawing process could take between one and six hours.
- Once the pipes have thawed, turn the water back on slowly and check for cracks and leaks.
If the above steps do not resolve the issue, you are unable to locate the frozen area, or it is not accessible, you may wish to contact a licensed plumber for advice.
You can also contact 311 and someone from the City will come to investigate. Please note that frozen pipes on private property are the responsibility of the homeowner (see the diagram).
