Pipe frozen by extreme cold

When the temperature is extremely cold, water pipes in your home or business may freeze. To help prevent frozen pipes, take the following precautions:

  • Check for open windows, air vents, and wind drafts near water pipes
  • Seal leaks in the basement foundation where cold air may enter; stuff holes with insulation; a tiny opening my cause an exposed pipe to freeze
  • Allow a slow trickle of water to flow through faucets connected to water pipes that run through unheated spaces
  • Keep sink cabinet doors open during cold spells to allow warm air to circulate around the pipes
  • Insulate pipes in unheated spaces like garages, basements, and crawl spaces
  • Locate the water shut off valve and know how to shut off water; if a pipe bursts, shutting off the water promptly can help minimize the damage
  • If your pipes freeze, use a hair dryer to thaw the lines safely; thawing will not be fast, but it will be safe: NEVER USE AN OPEN FLAME TO THAW PIPES

When pipes are frozen, there is often water available in at least one faucet. If there is no water coming through any of your taps, there may be a problem in your street or yard. Call BWSC’s 24-hour Emergency Assistance line at 617-989-7000.
