To protect pipes in an empty house during winter, keep the heat on at a steady temperature, turn off the main water valve, and drain the water lines if the house will be empty for a long time. Having someone check the home regularly adds another layer of safety.
Keep the Heat On
Turning the heat off completely is one of the most common reasons pipes freeze in empty homes. Most experts suggest keeping the thermostat at least in the mid-50s Fahrenheit. Open cabinet doors under sinks and leave interior doors open so warm air can reach pipes on outside walls.
Shut Off and Drain the Water
Closing the main shut-off valve limits how much water can escape if a pipe does burst. For longer absences, draining the system adds protection:
- Close the main valve
- Open faucets on the highest and lowest floors to let water out
- Flush toilets to empty the tanks
- Disconnect outdoor hoses and drain outdoor faucets
If the house has a boiler or other heating that uses water, ask a professional before draining anything, since shutting off water can affect those systems. The water heater may also need special steps.
Have Someone Check In
Ask a neighbor, friend, or family member to walk through the home every few days. They should look for water on floors, stains on ceilings, and make sure the heat is still running. A smart thermostat or a water leak sensor can send alerts to your phone if something goes wrong.
Before You Leave
Seal drafts around windows, doors, and where pipes pass through walls. Add foam insulation to pipes in the garage, basement, or crawl space. Make sure the sump pump works if you have one.
If you come back to a split or leaking pipe, getting the burst line repaired should happen before the water is turned back on. To prepare a vacant home for winter, you can arrange help from a local plumber by calling (833) 603-1840.
