Where Do I Find the Main Water Shutoff Valve?

Before water enters your house, it goes through three valves that are installed by the city. Finally, it has to go through your own main shutoff valve. When this valve is open, water can flow into your house. When the valve is off, so is your house’s water supply.

When you are experiencing a plumbing emergency, it is vital to know where your main shutoff valve is. Furthermore, you probably want to know its location well before you find your carpets are completely under water.

Your shutoff valve might be along an outside wall, but the first place you might want to check is a basement. There you might find the water line coming from the outside. After that, there should be a valve, then a water meter, followed by another valve. Then the line will continue to the house. The main shutoff valve will be the first valve on the supply line, the one in front of the water meter. Once you find this valve, you can turn it off by twisting it clockwise.

How to Shut Off Your Water Valve

Now your shutoff valve might be one of two different types. If your house has a gate valve, the good news is that this valve is typically long-lasting. The thing is, this valve is sometimes tricky to twist. Before you are in an emergency, you should test out this valve for yourself, finding out whether or not you can make it budge. Note that it could take several turns to close this valve off.

The other kind of valve you might have is a ball valve, which means it will have a handle. This is for residences with pipes made of plastic or copper. If water is flowing into your house, the valve handle will be parallel to the pipe. To turn off the valve, you will need to twist the handle so that it is at a right angle to the water line.

If you have turned your water supply off, this can avert further disaster, such as a broken pipe unleashing a flood. You are not done at this point, however. You might have to prevent further leaking at the valve stem. There will be a packing nut by this stem, which you can tighten, but only enough to cut off the leak. You do not want this nut to be too tight. When you are ready to turn the water back on, you will first need to take off the small screens, or aerators, that cap off all the faucets around the house. In this way, you can keep these aerators from getting blocked up with debris.

Cutting off your house’s water supply can be a good immediate response to a plumbing emergency. To get a permanent fix, however, you will probably need the help of an experienced Kansas City plumber.
