5 Essential Steps according to Levine Bros., Master Plumbers in Montreal
As cold weather sets in, residential plumbing systems are exposed to significant temperature variations that can lead to leaks, backflow issues, or costly damage.
“Winter puts plumbing to the test. One hour of prevention in the fall can save you weeks of repairs in January,” says Ben Levine, master plumber at Levine Bros.
Levine Bros., master plumbers in Montreal for over 100 years, recommends five simple steps to take before winter:
1. Locate and test shut-off valves inside the home
In the event of a leak, being able to quickly shut off the water is essential. Homeowners should locate the main shut-off valve, ensure it is easy to access, and test that it functions properly. Turning the valve once or twice a year helps prevent it from seizing and significantly reduces potential damage during an emergency.
2. Insulate any exposed piping in unheated areas
Certain areas of the home, such as partial basements, exterior perimeter walls, or closets against outside walls, are more prone to freezing. In these spots, pipes can cool quickly and crack. Targeted insulation, especially in older homes, helps prevent internal ruptures and avoids costly repairs.
3. Check and adjust system water pressure
Excessively high water pressure puts strain on joints, faucets, and appliances, often leading to premature leaks. Ideally, household pressure should be between 40 and 60 psi. Installing or adjusting a pressure regulator can help stabilize the system, especially in colder months. This protects the entire plumbing network and extends the life of the installations.
4. Inspect joints and fittings that may loosen
With temperature fluctuations, some fittings can gradually loosen. This often occurs under sinks, behind toilets, under bathroom vanities, and around dishwashers and washing machines. A quick inspection followed by a light preventive tightening can help avoid drips, seepage, or slow leaks that may cause significant damage before they are detected.
5. Have the main drain and backwater valve inspected
During winter, snowmelt and increased municipal pressure can raise the risk of backflow. A camera inspection of the main drain, along with a test of the backwater valve, helps identify roots, blockages, or sagging in advance. This preventive check significantly reduces the risk of sewer backups and basement infiltration.
