The short answer
Shut off and Drain the Water System
The most critical step is to stop water from flowing into the home. Locate the main water shutoff valve and turn it off completely. After shutting off the supply, you must drain all the water from the pipes, toilets, and water heaters. Open every faucet, both indoors and out, to let air in and push residual water out of the system.
Flush toilets to empty the tanks and bowls, and consider adding a non-toxic antifreeze to all drain traps. Do not forget appliances like the washing machine, dishwasher, and ice maker. Disconnect their supply lines and run a drain cycle if possible. This prevents any remaining water from freezing, expanding, and causing a pipe burst while the house is vacant.
Protect Plumbing Fixtures and Appliances
Individual fixtures need attention after the main system is drained. For sinks and showers, remove drain strainers and use a wet-dry vacuum to suck water from the P-trap underneath. You can pour a cup of plumbing antifreeze down each drain to protect the trap seal. For toilets, sponge out any leftover water from the tank and bowl to be thorough.
Water-using appliances are common sources of leaks. Turn off the water supply valves to the washing machine, dishwasher, and refrigerator icemaker. Disconnect the hoses and let them drain into a bucket. Running the dishwasher and washing machine through a short drain cycle can clear their internal pumps. Leaving appliance doors ajar prevents musty odors from developing.
- Turn off water supply valves to the washing machine and dishwasher.
- Disconnect appliance hoses and drain any remaining water.
- Run a drain cycle on appliances with internal pumps.
- Pour plumbing antifreeze into all sink, tub, and floor drain traps.
- Sponge out toilet tanks and bowls to remove residual water.
- Leave appliance doors slightly open to promote air circulation.
Conduct a Thorough Exterior Inspection
Walk around the property to identify potential entry points for water. Check the roof for missing, cracked, or loose shingles that could let in melting snow or rain. Inspect gutters and downspouts, clearing all debris so water is directed away from the foundation. Ensure downspout extensions are in place and point at least five feet away from the house.
Examine siding, windows, and doors for gaps or cracks where moisture could seep in. Seal any openings with appropriate exterior caulk. Look at the grading around your foundation; the soil should slope away to prevent pooling. Trim back tree branches that could break under ice or snow and damage the roof or siding.
Manage Interior Climate and Utilities
Decide whether to leave the heat on at a low setting or turn it off entirely. Maintaining a temperature above 55 degrees Fahrenheit can prevent freezing in walls if any moisture remains. If you turn the heat off, you must have fully drained the plumbing system. In either case, set your water heater to its "vacation" mode or turn it off completely.
Adjust other utilities for safety and efficiency. Unplug all non-essential electronics to protect against power surges. You may choose to turn off the circuit breaker for specific areas, like the kitchen. Leave the refrigerator and freezer empty, cleaned, and propped open. Notify a trusted local contact about your plans and provide them with emergency shutoff locations.
Prepare for Unexpected Water Damage
Even with careful preparation, leaks or storms can cause problems. Consider installing water leak sensors that can alert you via smartphone to rising moisture. Make sure a neighbor or property manager has a key and knows how to shut off the main water valve. Keep the contact information for local water damage pros handy in case a problem is discovered.
If you return to find water damage, act quickly to limit further harm. Do not enter if there is any risk of structural instability or electrical hazard. Shut off the main power at the breaker if it is safe to do so. Document any damage with photos for your records before starting cleanup or calling for professional help.
- Install wireless water leak sensors in high-risk areas like basements and under sinks.
- Provide a trusted local contact with a key and clear shutoff valve instructions.
- Save the contact information for professional restoration services in the area.
- If damage is found, prioritize safety before entering the affected space.
- Take photographs of any damage for insurance documentation purposes.
- Policies vary, and your insurer decides what is covered.

Should I leave the heat on in my winterized home?
It depends on your plumbing. If you completely drain the pipes, you can turn the heat off. If any moisture might remain in the walls, keeping the heat above 55 degrees Fahrenheit provides a safety margin against freezing and pipe bursts.
What if I cannot fully drain my hot water heater?
Many water heaters have a drain valve near the bottom. Connect a hose to direct water outside. If sediment blocks the valve, you may need a professional plumber. Turning the heater to "vacation" mode or off reduces energy use after it is drained.
How can I protect my home from roof ice dams?
Good attic insulation and ventilation keeps the roof cold and prevents snow melt. Before leaving, ensure your attic vents are clear. If ice dams are a known issue in your area, a roofer can install heating cables along the eaves as a preventive measure.
