You must act quickly to prevent water damage if water is streaming from an overflowing toilet, leaking pipe, or rusted-out water heater. 

Locating the main water shutdown valve is one alternative. If the leak is coming from a particular plumbing fixture, consider turning the valve behind it. Everything you need to know is right here.

Examine the Interior of the House

Start your search inside. Examine the boundary walls on the street side of the house.

The valve could be in your basement or crawlspace if you have one. Check near the water heater or inside the garage if your house is constructed on a slab. 

The main water shutoff valve should be located around ground level, regardless of its position. A plastic access panel may also be used to keep it safe.

Take a look at the streetside

If searching inside the house yields no results, it’s time to venture outside. Look for a rectangular metal cover flush with the ground near your property border. 

It’s possible that it’ll be labeled “water” or “water meter.” It’s possible that you’ll need a specific meter key to get into the box.

Examine your home inspection report

Are you still unable to locate the emergency shutoff valve? Read the plumbing part of the property inspection report from before you bought the house as a last resort. 

You should be able to obtain information regarding the location of the shutdown valve, putting an end to your search.

How to Shut Off the Water Main Valve

All you have to do now is turn off the valve once you’ve located it. Depending on the sort of valve you’re working with, follow these steps:

When open, a ball valve has a straight handle that runs parallel to the pipe. Turn the valve till it's perpendicular to the pipe to close it.

A gate valve is a circular valve with a round handle. To completely shut off the water, turn it clockwise several times.

You may be able to turn the house-side valve in the underground utility box by hand, or you may need a meter key or wrench. Twist the valve clockwise until the water goes off in either case.

Alternative: Turn off the water supply close to the source.

An isolation valve should be installed on every house plumbing fixture to shut off the water supply to it. 

As a result, turning off the water main should only be done if a pipe is leaking. Turn the isolation valve clockwise as far as it will go behind the device in question—whether it’s your toilet, sink, washing machine, or ice maker.
