Given the recent winter temperatures our area has been experiencing, the following can be done as possible preventative and proactive measures. It is a good idea to take a kitchen thermometer and let your cold-water faucet run to see your temperature. 3.33 degrees Celsius (38 degrees Fahrenheit) is considered a freezing point.
If you feel it is necessary to run your water to prevent service pipes from freezing, customers should follow these guidelines:
- Run water at the lowest pressure that a steady stream forms. Running water is no guarantee that pipelines will not freeze in all situations but is believed to be a helpful preventive measure. Run the water where damage will be minimal should the drain become plugged.
- Open a tap completely for two to three minutes at least twice each day. Before retiring and first thing in the morning usually are the most beneficial times. Check the continuously running tap several times each day to make certain it is not closed accidentally or by vibration. Placing a sign near the tap as a reminder for guests and children is a good idea.
- DO NOT use a hose or piping to connect a tap directly into the drain. This creates a cross-connection, a potentially serious health hazard.
- If your home will be unattended for more than twenty-four hours, have a friend or neighbor check it daily and fully open the tap for several minutes.
NOTE: No credit is available on water bills for water used to prevent freezing. This is strictly voluntary and will result in additional water usage and, therefore, slightly higher water bills.
