Preventing Water Pipes from Freezing
All materials contract as they get colder and colder and become more dense until the point where they freeze. Water is very unique. When it freezes, it actually expands and becomes less dense! That is why ice floats on top of water – it is less dense. This expansion is truly a Force of Nature – nothing can stop the 11% expansion. When the water is contained, as it is inside of a pipe, this expansion will rupture the pipe (or any other container – consider a frozen can of soda or bottle of wine)!
High-Risk Areas for Frozen Pipes
Pipes most at risk are those exposed to the cold, such as:
- Outdoor hose bibs
- Swimming pool and sprinkler supply lines
- Water pipes in unheated areas like attics, garages, crawl spaces, and cabinets on exterior walls
Pipes against exterior walls without sufficient insulation are also vulnerable.
Frozen Pipes Prevention Tips
- Monitor frozen pipe risks: Check for reduced water flow, especially on exterior walls or where pipes enter the foundation.
- Drain and disconnect outdoor hoses: Follow manufacturer instructions for draining swimming pool and sprinkler lines. Avoid using antifreeze in these lines due to environmental and safety concerns.
- Shut off inside valves: Close indoor valves supplying outdoor hose bibs and leave outside bibs open to drain.
- Insulate exposed pipes: Use pipe sleeves or heat tape to protect pipes in unheated areas like basements, attics, and garages.
- Keep the heat on: If you’ll be away, leave the thermostat set to at least 50°F.
- Open faucet valves: Keep taps open during extreme cold to prevent pressure build-up.
What to Do If Pipes Freeze
If you suspect a frozen pipe, look for reduced water flow from the faucet. Frozen sections are often near exterior walls or where pipes enter the home.
- Apply heat safely: Use a hair dryer, electric heating pad, or space heater to warm the pipe, starting at the faucet side. Never use open flames.
- Keep the faucet open: Thawing from the faucet side allows water or steam to escape, reducing the risk of pipe damage.
- Call a plumber: If you can’t locate or thaw the frozen section, call a licensed plumber. Check other faucets to ensure there are no additional frozen pipes.
After Thawing
Once thawed, turn off water lines to faucets and the icemaker. Monitor the water meter for leaks. If a pipe bursts, immediately shut off the main water valve and call a plumber.
