Cold Weather Could Lead to Frozen Pipes

While residents in the Town of Mooresville don’t deal with frigid temperatures for long durations of time, there is still the risk of pipes inside of homes freezing during the winter. When these pipes burst, it can lead to extensive water damage in a home, apartment, etc.

Water expands as it freezes, putting tremendous pressure on metal and plastic pipes. When temperatures drop below 20 degrees, there’s a high likelihood of pipes freezing.

What pipes are most likely to freeze?

  • Pipes exposed to severe cold, such as swimming pool supply lines and water sprinkler lines
  • Water supply pipes in unheated interior areas of a home – basement, crawl space, attic, garage, kitchen cabinets
  • Pipes that run against exterior walls with little to no insulation


What can homeowners due to prevent frozen pipes?

  • Leave heat on at least 55° F
  • Let water drip from faucets (kitchen, bathroom, garage, outdoor spigots)
  • Open kitchen, bathroom cabinet doors to allow warmer air to circulate and heat up pipes
  • Keep garage doors closed if there are water supply lines inside the garage


What should residents do when pipes freeze?

  • Keep the faucet open so as the frozen pipes are treated and begin to thaw, water will begin to flow through the pipes. Running water through the pipe will help melt ice inside the pipe
  • Apply heat to the section of pipe impacted – use a hairdryer on medium heat, use an electric heating pad, portable space heater (kept away from flammable materials), or wrapping towels soaked in hot water around the pipe
  • Do not use a blowtorch, kerosene or propane heater, charcoal stove, or open flame device
  • Apply heat until full water pressure is restored
  • If the frozen area is not accessible or cannot be located, call a licensed plumber
  • Check all other faucets in the home to determine if there are additional frozen pipes
