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 before you leave. This stops any supply line leak from flooding your home while you are gone. If you live in Caldwell, keep the valve location written down so you can find it quickly in an emergency.
After shutting off the valve, open a few faucets to drain remaining water from the pipes. This reduces pressure and lowers the risk of a burst pipe. Remember to close the faucets after the water stops flowing.
- Locate the main valve near your water meter or where the pipe enters the house.
- Turn it clockwise to shut off, then test a faucet to confirm.
- Drain outdoor spigots and disconnect hoses.
- Consider a smart water shutoff device that can be controlled remotely.
- If you have a sump pump, check that it works before you leave.
Protect Pipes from Freezing
Cold weather is a leading cause of water damage when you are away. In a semi-arid climate with cold winters and hot dry summers, pipes in unheated areas can freeze and burst. Set your thermostat to at least 55 degrees Fahrenheit, even if you are gone for a long time.
Open cabinet doors under sinks to let warm air reach the pipes. Insulate pipes in the attic, garage, or crawlspace with foam sleeves. If you have a crawlspace, check that vents are closed and insulation is in place.
- Keep the heat on, never below 55 degrees.
- Insulate pipes in unheated spaces.
- Seal gaps around pipes where cold air can enter.
- Let a slow drip run if you cannot shut off the water.
Unplug and Disconnect Appliances
Appliances that use water can leak even when they are not running. Unplug the washing machine, dishwasher, and refrigerator if they have a water line. If you cannot unplug the refrigerator, turn off its water supply valve.
Check hoses for cracks or bulges before you leave. A worn hose can burst under pressure. If you have an ice maker, turn it off and close its supply line.
Ask a Neighbor or Friend to Check
A trusted neighbor or friend can be your eyes while you are away. Ask them to walk through your home once a day or every few days to look for leaks, unusual sounds, or standing water. Give them a key and a list of emergency contacts.
If they notice a problem, they can shut off the main water valve and call a plumber. This can stop a small leak from becoming a major restoration project.
What to Do If You Return to Water Damage
If you come home to water damage, act quickly to protect your health and property. Turn off the water and electricity if safe to do so. Remove standing water with a wet vacuum or mop, and dry affected areas with fans and dehumidifiers.
For significant damage, contact local water damage pros. They have the equipment and knowledge to dry structures, prevent mold, and repair drywall or flooring. If you have insurance, document the damage with photos and contact your insurance company. Policies vary, and your insurer decides what is covered.

How long can a house be left without water damage?
There is no set time, but the risk increases with each day. Shut off the main water supply and set the heat to at least 55 degrees. Ask someone to check weekly. A small leak can cause significant damage within 24 to 48 hours.
Should I turn off the water heater when I go on vacation?
Turning off the water heater is not necessary if you shut off the main water supply. The tank will stay full and hot. If you turn off the gas or electricity to the heater, you risk damage. Leave the heater on, but turn off the water to the house.
What is the most common cause of water damage when away?
Burst pipes from freezing are common in cold weather. Supply line failures to washing machines or dishwashers also happen. Shutting off the main water valve prevents most of these issues. Check your policy to see what is covered; policies vary and your insurer decides.
