Winter Drain Care: How Freezing Temperatures Cause

When winter temperatures drop, most homeowners worry about burst supply pipes. However, freezing weather poses an equally severe threat to your home's drainage and sewer lines.

While incoming water supply lines are under constant pressure, drain pipes rely on gravity and smooth, unimpeded flow to carry wastewater away from your home. When freezing temperatures enter the equation, drain lines can quickly freeze, narrow, or collapse—leading to hazardous wastewater backups inside sinks, basements, and showers.
