Preparing Pipes for Winter Weather

November 07, 2008

As cold weather approaches, there are steps you may take to help prevent frozen pipes in your home. Water expands as it freezes, so water that is sitting in a pipe will place tremendous pressure on the pipe as it freezes. This pressure can cause the pipe to break.

Pipes that freeze most frequently are those that are exposed to the outside, such as outdoor hose outlets, water sprinkler lines and pool supply lines. Also at risk are pipes in unheated interior areas such as kitchen cabinets, attics, garages, basements and crawl spaces.

Before the onset of cold weather, help prevent frozen pipes by following these recommendations:
• Remove, drain, and store garden hoses.
• Close the inside valves that control the water supply to outside hose attachments, (known as bibs).
• Open the outside hose bibs to allow any water in the line to drain out. Keep this outside valve open so that any water remaining in the pipe can expand without causing the pipe to break.
• You may want to install a “pipe sleeve” for water pipes that are not insulated. Building supply stores carry these and other supplies for insulating pipes.
• If you go away for an extended time during cold weather, leave the temperature set above 55 degrees before you leave.
• In severe cold weather, let cold water drip from faucets served by exposed pipes. The cold water is still above freezing and will help prevent the pipe from freezing.

Spring cleaning isn’t just for closets and cabinets. DC Water’s system gets a refresh too!

Starting March 23, DC Water will begin work that helps maintain more than 1,300 miles of water lines across the District. During this time, the disinfectant used in drinking water will temporarily switch from chloramine to chlorine through May 4. This switch helps support overall water quality throughout the year.

Workers doing ongoing rehabilitation work

As work nears completion on the initial clean-up and temporary stabilization of the areas directly impacted by the Potomac Interceptor overflows, DC Water is beginning preparations for beautification and revegetation to restore native plants, trees, and shrubs.
