How to Turn Off Main Water Service

Tornadoes, hurricanes, floods, earthquakes, and plumbing emergencies are all times you'll want to turn off the water to your home. Know ahead of time where your shutoff valve is - just in case!

Difficulty:

Moderately Easy

Instructions

Things You'll Need

• Pipe Wrenches

1. Look for the shutoff valve outside if you live in a warm climate. It will typically be located where the water pipe enters the house and is usually at the most inaccessible spot behind stickery bushes. Find the water meter and you'll locate the main shutoff nearby.

2. Find your shutoff valve in the basement in cold climates - it may be set into a wall or on the water pipe leading to the water heater.

3. Locate the shutoff valves on either side of the pressure tank if your water comes from a ground well. Turn off both valves.

4. Shut off the water by turning the valve clockwise until it won't turn any more.

Tips & Warnings

• You may want to tag the valve to let others know you have turned it off. These plastic tags are available at hardware stores.

• Still can't find your main shutoff? Look for a rectangle-shaped access cover somewhere in your yard. Pry the cover up with a screwdriver. (Look inside with a flashlight before you stick your hand down in there - this is a favorite place for spiders to hide.)
