In cold weather, the potential for burst pipes is high, and the results of frozen and burst pipes often result in extensive and costly property damage.
- Disconnect, remove and store outdoor hoses. Close all inside valves supplying outdoor hose facets.
- Place an insulating dome or other covering on outdoor faucets and spigots.
- The Red Cross suggests installing specific products made to insulate water pipes like a “pipe sleeve” or installing UL-listed “heat tape,” “heat cable,” or similar materials on exposed water pipes.
- Inspect the area of the buildings were water supply lines are located in unheated areas, such as the basement, crawl spaces, garage, and under kitchen and bathroom cabinets. Be sure that all pipes in these areas are insulated
- As a safety measure, keep a wrench stored near the valves and make sure you know how to shut off water valves if a pipe bursts.
When a Cold Spell Hits
When you know the temperatures will drop to exceptionally low levels, please take the following precautions:
- Inspect the area around the pipes for any air leaks and seal leaks.
- Check the heating systems to ensure proper functioning.
- Check all faucets. Make sure water flows freely and no leaks are present. If you turn on a faucet and only a trickle comes out, this may be a sign of a frozen pipe.
- During deep freezes, the Federal Alliance for Homes recommends allowing a slow drip from your faucets to reduce the buildup of pressure in the pipes. Even if the pipes freeze, the release pressure in the water system will reduce the likelihood of a rupture.
- Open kitchen and bathroom cabinet doors to allow warmer air to circulate around the plumbing.
- Be sure you and family members know the location of all shut off valves; in the event a pipe bursts, you will need to stop the flow of water as soon as possible.
- For less frequented areas and unoccupied buildings, check heating and faucets two to three times a day to ensure there is no indication of frozen pipes. This is important as discovering a frozen line (no water flow) prior to the pipe thawing permits the opportunity to shut off the water before it leaks and may also provide an opportunity to thaw the pipe before the ice expands enough to split the pipe or fitting.
Treating Frozen Pipes
- If you open a faucet and little to no water comes out, leave the faucet open, turn off the water at the main shut-off valve, and call a plumber.
- Never attempt to thaw a frozen pipe with an open flame. You may be able to thaw a frozen pipe with the warm air from a hair dryer. Start by warming the pipe closet to the faucet, working toward the coldest section of the pipe.
- If a water pipe bursts, completely open all faucets and turn off the water at the main shut-off valve. Call a plumber immediately.
