How Illinois Homeowners Can Prevent Frozen Drain

Illinois winters can bring long stretches of freezing temperatures, and that cold can travel into uninsulated plumbing located in basements, crawl spaces, garages, and exterior walls. While frozen supply lines are well-known, drain lines are also vulnerable—sometimes causing blockages that are difficult to diagnose until they worsen.

Preventing frozen drain lines usually comes down to reducing exposure to cold, keeping water flowing when it’s at risk, and addressing common weak points where pipes can lose heat.
