Before You Start
◻️ Determine how long you will be away. Longer trips may require shutting off more plumbing systems.
◻️ Decide whether someone will check on your home during your absence.
◻️ Locate your home’s main water shut-off valve and verify that it operates properly.
◻️ Identify shut-off valves for toilets, sinks, washing machines, dishwashers, and ice makers.
◻️ Review any smart home monitoring devices or leak detection systems you already have.
◻️ Make sure you know how to restart appliances such as water heaters if they are turned off.
◻️ Gather emergency contact information for a trusted neighbor, family member, or plumber.
◻️ Check local weather forecasts if traveling during freezing temperatures.
Tools, Supplies, or Resources Needed
- Flashlight
- Adjustable wrench
- Garden hose (for draining a water heater if needed)

- Bucket
- Leak detection sensors (optional)
- Smart water shut-off system (optional)

Step-by-Step Checklist
◻️ Inspect all visible plumbing fixtures for leaks before leaving.
Look under sinks, around toilets, and behind appliances for moisture or drips.
◻️ Check faucets and showerheads for slow drips.
Even a small leak can waste water and become worse while you are away.
◻️ Inspect exposed pipes for corrosion, cracks, or signs of wear.
Address any problems before traveling.
◻️ Examine washing machine hoses.
Replace old rubber hoses that show cracking or bulging.
◻️ Check dishwasher and refrigerator water supply lines.
Look for kinks, leaks, or loose fittings.
◻️ Test toilets for leaks.
Listen for running water and ensure the tanks stop filling properly.
◻️ Empty and clean the garbage disposal.
Run cold water while operating the disposal to remove food debris and reduce odors.
◻️ Avoid leaving dirty dishes or food waste in sinks.
This helps prevent unpleasant smells and pest problems.
◻️ Run water in seldom-used drains.
This fills drain traps and helps block sewer gases.
◻️ Pour a small amount of water into floor drains.
Basement, utility room, and garage drains should have water in the trap.
◻️ Consider adding a small amount of mineral oil to infrequently used drains.
This can slow evaporation during extended trips.
◻️ Shut off the water supply to washing machines and ice makers if possible.
These appliances are common sources of water damage.
◻️ Turn off the main water supply if the home will be vacant for an extended period.
This greatly reduces the risk of a major plumbing leak.
◻️ Drain the plumbing system if you will be gone for a very long time or if freezing conditions are expected.
Consult a professional if you are unfamiliar with this process.
◻️ Set the water heater to vacation mode if available.
This saves energy while maintaining safe operation.
◻️ Turn off the water heater completely if recommended by the manufacturer and if the water supply will be shut off.
Follow the manufacturer’s instructions.
◻️ Protect exposed pipes from freezing if cold weather is expected.
Insulate vulnerable pipes and maintain adequate indoor temperatures.
◻️ Set your thermostat to a safe temperature.
Many experts recommend keeping the home at least 55°F during freezing weather.
◻️ Test leak detection devices and replace batteries if necessary.
Ensure notifications are working properly.
◻️ Verify that your smart water shut-off system is connected and functioning.
Test remote access before leaving.
◻️ Ask a trusted person to inspect the home during long trips.
Provide instructions on what to do if a leak is discovered.
◻️ Leave emergency contact numbers where they can be easily found.
Include your plumber, utility company, and a trusted neighbor.
◻️ Double-check that all outdoor faucets and hoses are secure.
Disconnect hoses if freezing weather is possible.
◻️ Confirm that sprinkler systems and irrigation controls are operating as intended.
Repair leaks or disable unnecessary watering schedules.
◻️ Perform one final walk-through of the house before leaving.
Look for anything that may have been missed.
Common Mistakes to Avoid
- Forgetting to locate the main water shut-off valve before an emergency.
