Winter is here! As a provider of drinking water and wastewater services, the Prince William County Service Authority (Service Authority) is committed to delivering uninterrupted service in all circumstances, including harsh winter weather. You can do your part, too. Taking a few simple steps throughout the winter, especially during severe cold snaps, can help keep your home or business warm and dry all season long.

Find Your Main Shut-Off Valve:

  • Locate the main water shut-off valve, mark it and make sure everyone in the household knows where it is.

Helping to Prevent Frozen Water Pipes:

  • Seal any air drafts around fixtures.
  • Insulate pipes in unheated areas.
  • When freezing weather is in the forecast, turn off the water to outside spigots and drain all water from the line.
  • Drain in-ground lawn irrigation systems. (Check manufacturer instructions for best method.)
  • Report broken or missing meter lids to the Service Authority to help prevent frozen meters.
  • Set the thermostat to no less than 55° F or simply shut off the main valve to protect pipes during extended absences from home in the winter.

If Your Water Pipes Freeze:

  • Turn on the closest cold-water faucet to relieve pressure from expanding ice in pipes.
  • Wrap towels soaked with warm water around pipes to gradually thaw them.
  • DO NOT attempt using a blow torch or hairdryer to thaw frozen pipes since intense heat can cause them to crack or burst.
