How to Locate Water Main Shut-Off Valve

How to Locate Water Main Shut-Off ValveAnytime there is a leaking or burst pipe inside the home, the initial step is to shut off the water immediately. Knowing where the main shut-off valve is located can make all the difference in protecting your home from water damage in an emergency. Follow this simple guide to locate all of the valves that provide water to the bathroom, kitchen, other rooms with a water source, as well as the water main shut off valve.


One of the easiest cutoffs to find is either directly underneath the sink or toward the lower area of the cabinet. It is easy to distinguish it because there are pipes running to the faucet. If you have a dishwasher, another valve can be located by following the additional pipe running from the sink’s hot water supply. It could also be in the basement below the dishwasher if your home has a lower level.


The toilet valve is often the most obvious as it is just beneath the tank and ovular in shape. Depending on the placement of the tub and sink, there may be one or two cutoffs in place. A sink’s supply is usually underneath, but it may be on the other side of the wall. If the bathtub valve is not in the sink vanity, it may be located directly underneath in the basement.

Laundry Room

Investigate around the washing machine to find the valve to the laundry room water supply line that is typically above or behind it.

Water Heater

In any circumstance that requires turning off the hot water heater alone, the cutoff valve is just above the appliance. Although this is rarely needed, it is always best to be prepared and find it beforehand.

The Entire House

It’s easy to find the water main shut off valve if you are familiar with the location of the water meter. Check nearby for a sturdy metal handle around waist level that controls or prevents water from entering the home. Anytime there is an issue and you need to quickly cut the water off, this is the most reliable way.
