In cold temperatures, water service lines can freeze if frost is pushed below the water line. Water lines inside the home can also freeze due to extreme wind chill and cold drafts.
Repair costs associated with frozen pipes are the responsibility of the homeowner. You can help prevent frozen pipes by keeping your home heated at normal levels to avoid cold spots.
The sooner a frozen line is thawed, the better. Over time, freezing will extend further along the line and make thawing more difficult, time-consuming and potentially more costly.
To prevent a frozen water line
Insulate the outside lines: wrap any water lines near outer walls or doors with insulation. You can wrap your exterior water lines with heat tape to help prevent pipes from freezing.
Keep the water flowing: frequently drawing water from the tap may prevent freezing because it creates a regular flow of water.
- Let the water drip from the faucet: running water through the pipe—even a trickle—helps prevent pipes from freezing.
- Keep your bleeder valve turned on: If you have a bleeder valve in your home do not turn it off. EPCOR will notify you when it's time to do so.
Turn off outdoor hoses: double check your outside hose faucet to ensure they're closed off; if they freeze, they can burst and may cause water to drain into your home.
Check your hot water tank: if your hot water tank is located in a maintenance room outside of your home, make sure the area is adequately heated.
Ask your house sitter to run the water: if you are going away on vacation, ask the person who is checking in at your home to run the taps as running water through the lines in cold weather makes it less likely that they'll freeze.
Don't forget about outdoor water features: if you have a pool or decorative water feature, turn the motor on and keep the pump running and the water circulating.
To determine if a service line is frozen
You can help diagnose the problem by turning on all the faucets inside the house and flushing each toilet. If no water is flowing from any fixture and there is no known water main break in your area, it's likely you have a frozen service line outside your home on your property.
