How to Prevent Frozen Pipes?

January 27, 2023

Winter brings bitterly cold weather, and when temperatures drop, the water pipes face a potential risk of freezing resulting in frozen water in home fixtures. An abrupt drop in temperature or inadequate insulation is one of the common reasons for frozen pipes. A frozen water line can cause pipes to burst, resulting in damage. When pipes freeze, the increased internal pressure can lead to pipe bursts and subsequent water damage to the home. The optimal time to winterize is before cold temperatures start dropping. Consulting with a Sacramento plumber is necessary to prevent pipes from freezing during cold weather and avoid plumbing problems.

According to research by the Building Research Council at the University of Illinois, the “temperature warning threshold” is 20° F, particularly where pipes have no insulation and run through a non-insulated space.

Here Are the Tips to Prevent Frozen Pipes

  • Pipe insulation is inexpensive and an effective solution to frozen pipes. You might want to insulate pipes installed in the attic, basement, crawl spaces, or garage. Additionally, consider installing foam insulation in kitchen and bathroom sinks that are vulnerable to freezing. Consulting with a reliable HVAC company in Sacramento can help you find the best solution.
  • Keeping garage doors closed can help avoid frozen water supply pipes installed there.
  • Maintain the same setting for the thermostat every day. Also, lowering the thermostat at night to reduce heating costs cannot work well.
  • Keep the heat on in your house, set to 55° F, if you intend to spend time away during cold weather.
  • Keep the outer valve open so that any water inside the pipe can expand without breaking.
  • When freezing weather is coming, turn off the water to outside spigots and drain all water from the line.
  • Sealing air leaks can be effective in preventing frozen pipes. Check your house for holes or gaps that can allow chilly air in. Fill in any gaps around the piping in the interior or exterior walls.
  • Draining outdoor water lines is recommended. Every fall, homeowners should disconnect and drain hoses or outdoor water connections to sprinkler systems and swimming pools to winterize their homes and garden.
  • Uninsulated pipes under sinks are exposed to colder temperatures when you keep cabinet doors closed because heat cannot reach them. You are recommended to open the cabinets to prevent frozen pipes.

Water increases by around 9% in volume when it freezes. The pressure inside pipes may increase from 40 pounds per square inch to 40,000 psi. That much pressure is beyond the capacity of any pipe. Therefore it bursts.

Long-term freeze prevention typically entails a significant job, such as insulating crawl space and switching out conventional outside faucets for frost-resistant versions. You can consult a plumber for rerouting pipes inside the house where they are accessed to heat.


Take the essential precautions to prepare your home before the temperature outside drops below freezing, and learn how to avoid frozen pipes. Knowing a few tricks can help prevent frozen pipes and keep the water running in cold weather.
