The short answer

Shut off the Main Water Valve

The single most effective step is to turn off the water at the main shutoff valve. This stops water from flowing into your home, so even if a pipe bursts, the damage is limited to whatever water is already in the lines. Locate the valve before you leave, usually near the water meter or where the main line enters the house.

If you live in Burnsville, keep the shutoff valve location written down and visible, so a neighbor or house sitter can find it quickly. Practice turning it off and on once to ensure it works smoothly. A stuck valve is a common problem, so address any stiffness before your trip.

Drain the Pipes

After shutting off the main valve, open all faucets, including showers and outdoor spigots, to let the remaining water drain out. Flush toilets to empty the tanks and the lines. This reduces the amount of water that could leak and also lowers the risk of freezing in cold weather.

For homes with a well, drain the pressure tank as well. If you have a sprinkler system, follow the manufacturer's instructions for winterizing. Draining the system takes only a few minutes but can save you from a major cleanup when you return.

  • Turn off the main valve
  • Open all faucets and spigots
  • Flush toilets to empty tanks
  • Drain the water heater if needed
  • Close faucets after draining

Adjust the Water Heater

Turn the water heater to vacation mode if it has that setting, or switch it off entirely. This saves energy and reduces the risk of overheating if the tank is empty. If you drain the water heater, be sure to follow the manufacturer's steps to avoid damage.

If you leave the water heater on, keep the pilot light lit for gas models, but lower the temperature. An empty tank with the heating element on can damage the unit. When you return, refill the tank before turning the power back on.

Prevent Freezing in Cold Weather

Cold weather can cause pipes to freeze, even when the water is shut off. Insulate exposed pipes in unheated areas like basements, crawl spaces, and garages. Use foam pipe insulation or heat tape, and seal any gaps where cold air can reach the pipes.

Even with the water shut off, residual water can freeze and crack pipes. If you cannot drain every drop, consider adding antifreeze to traps and toilets, but only for homes that will be empty for a long time. Keep the thermostat at a minimum of 55 degrees Fahrenheit to help maintain warmth.

  • Insulate pipes in unheated areas
  • Seal gaps and cracks near pipes
  • Keep the heat at 55 degrees or higher
  • Drain outdoor spigots and hoses
  • Use heat tape on vulnerable pipes

Install a Leak Detector

A simple leak detector placed near the main valve or under sinks can alert you to a leak via your phone. These devices are inexpensive and easy to install. Some models also shut off the water automatically when they sense moisture, providing extra protection.

If you have a smart home system, integrate the detector with your existing setup. Even if you are away, you can receive an alert and ask a neighbor to check. This small step can help you catch a problem early, reducing the need for extensive water damage restoration.

Frequently asked questions

Should I turn off the water heater when I go on vacation?

Yes, it is a good idea to turn off the water heater or set it to vacation mode. This saves energy and prevents damage if the tank is empty. For gas heaters, keep the pilot light on, but lower the temperature. Always refill the tank before turning it back on.

What if I have a smart leak detector?

Install it near the main shutoff valve or under sinks. It will send an alert to your phone if it detects moisture. Some models can automatically shut off the water, which is useful when you are away. Test it before you leave to ensure it works.

Do I need to drain all the pipes if I leave in summer?

Draining is still a good precaution because it reduces the risk of leaks from pressure or temperature changes. Even in summer, a pipe can burst due to wear. Shut off the main valve and drain the lines to minimize any potential water damage.
