Should I Turn Off Water While On Vacation?

When It Makes Sense

• Good fit: You own a home in a region that experiences freezing temperatures and will be away for more than a week, so shutting off the main water supply helps prevent burst pipes.
• Good fit: You have a rental property or a second home you won’t occupy for an extended period and want to avoid wasteful water usage or potential leaks while you’re gone.

When You Should Avoid It

• Warning sign: Your plumbing includes fixtures or appliances (like a water‑based heating system) that must remain pressurized, making a full shut‑off risky or disruptive.
• Warning sign: You expect to return early, need water on short notice, or rely on the water supply for medical equipment or essential garden irrigation.

Pros and Cons

Pros

• Reduces the risk of water‑related damage such as leaks or burst pipes while you’re absent.
• Saves water and can lower your utility bill during the period the house is unoccupied.

Cons

• If you return unexpectedly, you may face inconvenience and need to restore water pressure, bleed air, and check for leaks.
• Improperly draining the system in cold climates can still result in frozen pipes, which may cause damage if not done correctly.

Decision Checklist

• How long will you be away, and does the duration increase the risk of leaks or freezing?
• Is your home’s plumbing system compatible with a full shut‑off (e.g., no water‑dependent appliances that must stay on)?
• Do you have a reliable method to safely drain, shut off, and later restart the water system without causing air pockets or pressure issues?

Alternatives to Consider

Instead of a complete shut‑off, you might install an automatic main‑water shut‑off valve that triggers on leaks, use a frost‑proof pipe insulation kit, shut off only specific zones (like outdoor irrigation), or leave a faucet slightly open to allow drainage while maintaining minimal flow.

Final Recommendation

For most homeowners taking an extended vacation—especially in colder climates—turning off the main water supply is a prudent step to mitigate damage and conserve resources. If your trip is brief, your plumbing system requires continuous water pressure, or you need water on short notice, consider targeted shut‑offs or leak‑prevention devices instead. When in doubt, consult a qualified plumber to ensure the approach fits your home’s specific setup.
