How do I protect outdoor plumbing in winter?

Protecting outdoor plumbing from freezing is essential in Ottawa's harsh winters - frozen pipes can burst and cause thousands in water damage when they thaw in spring.

Start with your outdoor faucets and hose bibs. Disconnect and drain all garden hoses completely, then store them indoors or in an unheated garage. Even a small amount of water left in a hose can freeze and back up into your home's plumbing. Next, shut off the interior water supply valve to each outdoor faucet - these are typically located in your basement near where the pipe exits to the exterior. After closing the valve, go outside and open the faucet to drain any remaining water from the line.

For pipes in unheated areas like crawl spaces, garages, or exterior walls, insulation is your best defense. Foam pipe insulation sleeves are inexpensive and effective for most situations. Pay special attention to pipes near exterior walls, in unheated basements, or anywhere cold air can reach them. In extremely cold areas, consider heat tape or cables designed for pipes, but these must be installed according to manufacturer instructions to prevent fire hazards.

Ottawa's climate demands extra attention to foundation and basement areas. Ensure basement windows are properly sealed and consider adding extra insulation around pipes near the foundation. If you have a sump pump, make sure the discharge line won't freeze - a frozen discharge can cause basement flooding during winter thaws.

For extended winter absences, consider having your water main shut off and pipes drained by a professional. This prevents any possibility of freeze damage while you're away. Keep your home heated to at least 15°C (60°F) even when vacant, and have someone check on the property regularly.

If you discover a frozen pipe, act quickly but safely. Never use open flames or high heat - instead, use a hair dryer or heating pad to gradually warm the pipe starting from the faucet end. If you can't locate the freeze or if a pipe has burst, shut off your main water supply immediately and call for emergency plumbing service.
