How to locate the whole-house water shutoff valve -

The most important point to know in a flooding emergency is your home’s main water valve to shut off water at the source.

This valve is located around waist level or lower, on the inside basement wall, closest to your street or well, where the water comes in from outside the home.

Many water meter setups have two valves, one on the street side of the meter and one on the house side. You’ll typically find the main shutoff in the basement near the front of the house.

If you pipe in water from the city, the water meter is always mounted next to the main, and the valve itself will be large, metal and have a very sturdy handle. In a home with metered water, look for the shutoff on either side of the water meter. Your meter could be located in the basement, mounted on an exterior wall, or even out near the street in a concrete "meter pit" where the household feed line meets the utility main.

For a home served by a well, the shutoff will be on the house side of the pressure tank. You should also cut power to the tank so it doesn't detect a phantom pressure loss and burn out trying to compensate.

It could be outside your home attached to an exterior wall or in an underground box with a removable lid.

There are two types of main shutoff valves: the gate valve and the ball valve.

The gate valve is common in older homes and has a round handle that must be turned a number of times to open or close the valve. Gate valves are designed to be fully open or fully closed. Water flowing through a partially open gate valve can wear away the metal and cause the valve to fail over time.

The ball valve is more common in newer construction and has a lever handle that needs to be turned 90 degrees to turn the water on or off. You can immediately tell if it’s open or not: In the closed position, the lever is perpendicular to the pipes; in the open position it’s parallel.

If you’ve never shut off the main water valve before, test it to make sure it turned everything off. Turn on a faucet somewhere in the house and shut off the main water valve. All water flow should stop.

An old gate valve can break, so be gentle when you’re handling it. If the valve is stuck, leave it alone. If it leaks or doesn’t shut off all the way, replace the valve. You’ll need to call your water department (and possibly pay a small fee) to have the water to your house turned off at the curb stop during repairs.

If you have a well, shut off the electrical switch for the well when you leave for an extended period so it won’t pump any water while you’re gone.

Whole-house hot-water shutoff. On your water heater, there should be a valve on the hot-water outlet, which controls all of the hot water to the house. If there isn't one on yours, you or your plumber should install one.

Toilet shutoff. Look for this inline shutoff — typically a ribbed oval handle — under the toilet tank.

Sink shutoffs. These inline shutoffs usually sit just beneath the sink or within the cabinet or vanity. The one on the left is usually for the hot water, the one on the right for cold water. It could be hidden from view for aesthetic reasons in your ceiling or floor, but it will still be right near the sink.

Dishwasher shutoff. Look first under the kitchen sink. Often there's a reducer coupling and shutoff valve leading to the dishwasher on the 1/2-inch hot water sink-supply line. Not there? If you have a basement, look between the ceiling joists just below the appliance.

Turning off water to the clothes washer. There should be valves where the house-supply lines meet the washer hoses. Washer hoses are notoriously weak, so always close the valves when leaving home for an extended period.

When pipes burst, plumbing leaks, or appliances cause a flood, cut off the water at its source IMMEDIATELY. Water damage from frozen pipes, ruptured washer hoses, leaking supply lines and dripping water heaters costs billions every year. Avoid major water damage problems in your house by knowing how to shut off your water.

Take a moment right now to locate all of the shutoff valves in your home so you'll be prepared for an emergency…

Also, you should check your water valves and pipes for leaks.

How To Do A Sump Pump Test

Test your sump pump: Dump water down the sump pit to raise the water level, and make sure the pump is ejecting the water properly.

If you need water damage repair after you shut off the water during a flood or flooding emergency, call a qualified water damage restoration contractor and your insurance carrier.

We had a flood enter our business that caused a lot of damage and we hired another company to fix it, but they did not do it right and mold set in! When we realized what had been happening, we called SERVPRO even though originally their quote was higher so that was why we chose the other company. Glad we called in the real pros because they pulled off the impossible task of killing mold and the property opened back up without any more problems, because SERVPRO fixed the damages caused by the other restoration company and fully got rid of all the mold once and for all. In the end, it cost us more by not choosing SERVPRO first, so next time, if we ever have another need for this kind of thing, we will call SERVPRO first! They were worth every penny that hiring them first would have saved us. ~ Matt W. in North Beach Haven, NJ    After we had flooding with the storm, the SERVPRO team was very knowledgeable and were able to clean everything up with a bunch of machines that measured moisture inside walls and floors and more machines that got water out of them. They rebuilt all the areas by removing parts of walls and flooring that needed to be replaced with new wood, etc. When they were done, the house was clean and pretty! ~ Jenn L. in Hammonton, NJ
