Preventing and Thawing Frozen Pipes

Water Cleanup New Haven CT, Water Damage Cleanup New HavenWith the temperatures beginning to drop, coats are coming out, wool socks are being slipped on, and your hats and gloves are making their way out of hiding. But even though these events might be exciting for some people, the dropping of temperatures also brings the freezing of pipes.

Why Frozen Pipes Cause a Problem

Water has a unique property in that it expands as it freezes. This expansion puts tremendous pressure on whatever is containing it, including metal or plastic pipes. No matter the “strength” of a container, expanding water can cause pipes to break. Pipes that freeze most frequently are those that are exposed to severe cold, like outdoor hose bibs, swimming pool supply lines, water sprinkler lines, and water supply pipes in unheated interior areas like basements and crawl spaces, attics, garages, or kitchen cabinets. Pipes that run against exterior walls that have little or no insulation are also subject to freezing.

Prevention

Before the onset of cold weather, prevent freezing of these water supply lines and pipes by following these recommendations:

  • Drain water from water sprinkler supply lines following manufacturer’s or installer’s directions. Make sure you do not put antifreeze in these lines unless directed. Antifreeze is environmentally harmful and is dangerous to humans, pets, wildlife, and landscaping.
  • Remove, drain, and store hoses used outdoors, close inside valves supplying outdoor hose bibs, open the outside hose bibs to allow water to drain, keep the outside valve open so that any water remaining in the pipe can expand without causing the pipe to break.
  • Check around the home for other areas where water supply lines are located in unheated areas. Look in the basement, crawl space, attic, garage, and under kitchen and bathroom cabinets. Both hot and cold water pipes in these areas should be insulated.

When the Temperature Drops

  • Keep garage doors closed if there are water supply lines in the garage.
  • Open kitchen and bathroom cabinet doors to allow warmer air to circulate around the plumbing. Be sure to move any harmful cleaners and household chemicals up out of the reach of children.
  • When the weather is very cold outside, let the cold water drip from the faucet served by exposed pipes. Running water through the pipe – even at a trickle – helps prevent pipes from freezing.
  • Keep the thermostat set at the same temperature both during the day and at night. By temporarily suspending the use of lower nighttime temperatures, you may incur a higher heating bill, but you can prevent a much more expensive repair job if pipes freeze and burst.
  • If you will be going away during cold weather, leave the heat on in your home, set to a temperature no lower than 55° F.

After the Damage is Done

If you turn on a faucet and only a trickle comes out, you can suspect a frozen pipe. Places this will most likely occur include exterior walls or where your water service enters your home through the foundation. Here are some things you can do to thaw frozen pipes.

  • Keep the faucet open. As you treat the frozen pipe and the frozen area begins to melt, water will begin to flow through the frozen area. Running water through the pipe will help melt ice in the pipe.
  • Apply heat to the section of pipe using an electric heating pad wrapped around the pipe, an electric hair dryer, a portable space heater (kept away from flammable materials), or by wrapping pipes with towels soaked in hot water. Do not use a blowtorch, kerosene or propane heater, charcoal stove, or other open flame devices.
  • Apply heat until full water pressure is restored. If you are unable to locate the frozen area, if the frozen area is not accessible, or if you cannot thaw the pipe, you might want to call a licensed plumber.
  • Check all other faucets in your home to find out if you have additional frozen pipes. If one pipe freezes, others may freeze, too.

If you experience water damage due to frozen pipes, contact a professional water restoration company like PCS of Connecticut.
