Freezing Facts:
- 11-20% of homeowner’s insurance claims are due to water damage from freezing pipes. (The average cost of this damage is $7,307.)
- 250,000 homes experience frozen and/or burst pipes in the U.S.
- Water expands to 10% of its size when it freezes.
What Causes Frozen Pipes?
Pressure – The typical cause of frozen pipes is pressure from the unfrozen water between the closed faucet and the ice. Poor insulation – Especially if your house was built before the 1960’s (when insulation quality started improving), you could be at risk of frozen pipes. Bends in the pipe – The expansion of the frozen area can be trapped by bends in the pipe. Old pipes – Debris tends to build up in old pipes, therefore making them more likely to freeze.How Do You Prevent Frozen Pipes?
- Insulate (with foam) any pipes that are in colder areas of your home,
- Replace old plumbing.
- Re-route any pipes that are exposed to the cold.
- Seal any insulation gaps near plumbing.
- Turn off any valves for your outdoor water supply. Make sure the tap is empty and shut it tightly.
- Allow warm air to circulate to your home’s coldest areas, especially if your plumbing is vulnerable in that area. For example, open cabinets under sinks.
- You may want to set your heating system to maintain a warmer temperature overnight.
- Open faucet taps to allow a slow drip of water.
- Have someone monitor your home (both inside and out).
- Turn off your hot water tank.
- Consider shutting the main water valve to your home and draining the plumbing.
- Keep your heat set to a normal temperature.
