Leaving your home for an extended vacation requires careful planning, especially when it comes to your plumbing system. Without proper precautions, leaks, bursts, or other plumbing issues can cause significant damage while you’re away. This guide provides actionable steps to ensure your plumbing system remains in good condition during your time away.

Steps to Maintain Your Plumbing System Before Leaving

1. Shut Off the Main Water Supply

Turning off the main water supply is one of the most effective ways to prevent plumbing disasters.



  • Why It’s Important:
    • Prevents water from flowing into your home in case of leaks or pipe bursts.
  • How to Do It:
    • Locate the main water shutoff valve, usually near your water meter or in the basement.
    • Turn the valve clockwise to shut off the water supply.
    • Test by running a faucet to ensure no water flows.

2. Drain Your Pipes

  • Steps to Drain Pipes:
    • After shutting off the water supply, open all faucets and flush toilets to empty the lines.
    • Leave faucets open to allow air to circulate.

3. Set Your Water Heater to Vacation Mode

Adjusting your water heater saves energy and prevents potential issues.

  • Tank-Style Water Heaters:
    • Set the thermostat to "Vacation Mode" or the lowest temperature setting.
    • Alternatively, turn off the heater entirely if you’re comfortable relighting the pilot upon return.
  • Tankless Water Heaters:
    • Follow the manufacturer’s instructions for vacation settings or shut off the system.

4. Inspect for Leaks

A thorough inspection before leaving can help you identify and address minor issues.

  • Where to Check:
    • Faucets, under-sink pipes, toilets, and around water heaters.
    • Look for drips, pooling water, or rust stains.
  • Fix Minor Issues:
    • Tighten loose connections or replace worn washers to prevent leaks.

5. Clear Drains

Ensure all drains are clear to avoid clogs and odors while you’re away.

  • How to Clear Drains:
    • Use a mixture of baking soda and vinegar followed by hot water to clean drains.
    • Remove debris from sink and shower drains with a drain snake or strainer.

6. Shut Off Outdoor Water Sources

Prevent leaks and frozen pipes in outdoor plumbing.

  • Steps:
    • Disconnect and store garden hoses.
    • Turn off outdoor spigots and drain any remaining water.
    • Shut off the valve for outdoor sprinkler systems.

3. Maintain a Safe Indoor Temperature

If you’re leaving during cold weather, keep your home warm enough to prevent frozen pipes.

  • Recommended Temperature:
    • Set your thermostat to at least 55°F (12°C) to keep pipes warm.
    • Open cabinet doors under sinks to allow warm air to circulate.

4. Prevent Sewer Odors

Unoccupied homes can experience sewer odors if drains dry out.

  • How to Prevent Odors:
    • Pour a small amount of mineral oil or antifreeze into drain traps to keep them sealed.
    • Close toilet lids to prevent odors from escaping.

Returning Home After Your Vacation

1. Turn On the Water Supply Slowly

2. Check for Leaks

Inspect all plumbing fixtures and connections for signs of leaks after turning the water back on.

Run water through all faucets for a few minutes to clear stagnant water and remove any odors.

4. Restart the Water Heater

If you turned off your water heater, follow the manufacturer’s instructions to restart it safely.
