The best way to prevent a frozen sewer line in Minnesota is to keep warm water moving through it, keep the home heated, and protect the ground above the line. Most freeze-ups happen during long stretches of below-zero weather, especially in homes that sit empty or use very little water.
Why do sewer lines freeze in Minnesota?
Sewer lines freeze when cold reaches the pipe faster than warm wastewater can keep it above freezing. Shallow sections of pipe, lines under driveways where snow is cleared, and properties with low water use are the most at risk.
How can I keep my sewer line from freezing?
- Use water regularly. Warm water from showers, laundry, and dishwashers helps keep the line from freezing.
- Keep the home heated. Never let a property drop to an unsafe temperature, even when you're away.
- Leave snow cover where you can. Snow insulates the ground. Avoid packing down or clearing snow over the sewer line when possible.
- Watch for slow drains in a cold snap. A gradual slowdown can be an early warning.
- Plan for seasonal properties. Lake homes and cabins that sit empty need extra attention before winter.

What are the signs a sewer line is frozen?
Drains that stop working during extreme cold, toilets that won't flush, and backups across the whole house are all signs of a frozen sewer line or vent.
What should I do if a pipe breaks?
If a pipe breaks, shut off the main water valve and call us.
Then stop using water in the home. Don't try to thaw a line with an open flame.
