Frozen water service lines
We explain how to prevent and respond to a frozen water line.
When it happens
Water lines can freeze during very cold winter weather if
- The depth of the frost reaches the depth of the service line, or
- Your basement is not heated where the water service line enters the home
How you know
How to avoid
Keep temperatures above freezing in basement spaces where
- The service line enters the home
- The water meter sits
- If your meter is in a separate room or cabinet, leave the door to the room open to aid air flow.
Keep a faucet in the lowest level of your home running a trickle of cold water until the ground thaws.
- You only need to run a pencil-width stream of water.
- Make sure your drain is free of debris to prevent overflowing or flooding.
- Place a visible note on the faucet reminding other people in your home to not turn the water off.
- Turning the water off, for even a few minutes, can cause a recently frozen line to freeze again.
- Do not turn the faucet off until the ground is fully thawed.
If you have a service line that often freezes
- Keep the basement temperature above freezing in the winter.
- Consider hiring a qualified contractor to lower your service line. Lower it to a depth that it can't be reached by frost.
