Check Your Pipes Right Now — Temperatures Are About to Plunge Below Zero in These States

December 15, 2025

As a significant cold front approaches, temperatures in multiple states are set to plunge below zero, raising the alarm for homeowners. This winter surge poses a severe risk of frozen pipes, which can lead to devastating water damage and costly repairs. The impending chill brings not only frigid air but also the potential for snow, further complicating plumbing systems. With December 13-14 as critical dates to monitor, it’s crucial to take immediate steps to protect homes from freezing pipes.

In brief:

  • Temperatures dropping below zero in several states pose a risk of frozen pipes.
  • Exposed and uninsulated pipes are especially vulnerable to freezing.
  • Preventative measures include insulating pipes, sealing gaps, and keeping interiors heated.
  • Letting faucets drip can prevent pressure build-up in the plumbing system.
  • If pipes freeze, acting quickly is essential to prevent bursts and extensive damage.

Understanding the Risk of Freezing Pipes

When temperatures drop significantly, the risk of frozen pipes increases drastically. As water freezes, it expands, creating immense pressure within the pipes. This pressure can cause even the toughest materials to crack or burst, resulting in flooding and substantial repair bills. In units with inadequate insulation, especially those in areas that historically experience milder winters, the threat is heightened.

Key Areas Where Pipes are Most Vulnerable

Homes that feature uninsulated or poorly insulated plumbing systems are at a higher risk. The following areas should be inspected closely:

  • Exposed pipes in basements and attics
  • Pipes running through exterior walls
  • Areas under sinks and cabinets, especially on outside walls

Preventative Measures to Safeguard Your Plumbing

To avoid the calamity of frozen or burst pipes, taking precautions is essential. Here are actionable steps homeowners can implement:

  • Insulate Exposed Pipes: Pipe insulation sleeves help maintain warmth. These can be easily purchased and installed in vulnerable areas.
  • Seal Cracks and Gaps: Inspect and mend any leaks around doors and windows. Using products like weatherstripping or caulking can keep cold air out.
  • Keep Your Home Warm: Ensure consistent heating, even during outages. Utilize portable heaters or generators as needed.
  • Let Faucets Drip: Allowing a slight drip from faucets can relieve pressure and prevent freezing.
  • Drain Outdoor Faucets: Disconnect garden hoses and install insulated covers to shield outdoor plumbing.

Emergency Steps if Pipes Freeze

If pipes are suspected of freezing, acting swiftly can mitigate damage. First, turn off the main water supply to prevent flooding if a pipe bursts. Then, try to gently thaw the pipes using a hairdryer or heat tape. Avoid open flames at all costs, as this can cause further damage and hazards. In cases where the pipe remains frozen or bursts, contacting a professional plumber immediately is crucial.

Current Weather Forecast and its Implications

With wind chills expected to reach dangerous levels across Indiana and beyond, the cold snap poses a significant threat, particularly for less insulated homes. The rule of thumb is that temperatures need to remain below 20 degrees for four to six hours consecutively to risk freezing pipes. Residents in states north of the Ohio River are especially urged to prepare as forecasts predict several days of relentless cold.

Monitoring the Situation

Staying informed about local weather updates is crucial during this time. Check this guide for additional tips on protecting outdoor faucets, and consider installing smart solutions like a smart thermostat to manage home heating efficiently.
