Should I Shut My Water Off When On Vacation?

When It Makes Sense

• Good fit: You are leaving for a week or more, live in a climate where temperatures stay well above freezing, and your home has relatively new plumbing with no known leaks.
• Good fit: Your property will be unoccupied, you have no automated irrigation or pool systems that require water, and you have a trusted neighbor or property manager to monitor the home.

When You Should Avoid It

• Warning sign: You are traveling to an area where winter temperatures may cause pipes to freeze; shutting off water without proper winterization can lead to burst pipes.
• Warning sign: Your home relies on water‑dependent devices such as a humidifier for a wood‑floor climate, a medical dialysis machine, or a well pump that needs continuous pressure.

Pros and Cons

Pros

• Reduces the risk of water‑related damage from burst pipes, leaks, or faulty appliances while you are away.
• Can lower water usage and utility bills, especially for long trips.

Cons

• Shutting off water may cause pipes to freeze in cold climates, potentially creating more damage than leaving them on.
• It disables water‑dependent safety systems (e.g., fire sprinkler pre‑charge) and may inconvenience you if you need water unexpectedly on return.

Decision Checklist

• How long will you be away and what is the forecasted temperature range for your area during that period?
• Do any fixtures, appliances, or systems in your home require a constant water supply?
• Do you have a reliable method (neighbor, manager) to monitor the property and address emergencies?

Alternatives to Consider

Instead of a full shut‑off, you can install an automatic shut‑off valve that activates if a leak is detected, or use a frost‑protective pipe wrap for vulnerable sections. Draining only the exposed piping while leaving interior loops filled can protect against freezing while still allowing limited water flow for essential devices. For short trips, simply turning off the main water line at the meter may be unnecessary; simply check for leaks before departure.

Final Recommendation

If you are away for a week or more, live in a warm climate, and have no water‑dependent systems, turning off the main water supply is a prudent precaution. In colder regions or when critical devices rely on water, consider partial winterization, leak‑detecting valves, or consulting a plumber to assess the safest approach. Always involve a qualified professional for high‑risk scenarios such as freeze‑prone areas or complex plumbing setups.
