It’s important to know how to shut your main water valve off in case you have an emergency or need to make repairs. We totally understand if you’re frustrated while looking for this valve since there is no standard location for it. We’ve got your back. Read on to find out all the possible locations for your home’s main water supply shut-off valve.

This article is based on an interview with our professional plumber, Dave Jones. Check out the full interview here.

Things You Should Know

  • Your shut-off valve is likely in your basement on the wall closest to the street.
  • If the valve isn’t in your basement, it may be on an exterior wall or under a panel in your front yard.
  • For round valve handles, turn clockwise to shut off the water and counter-clockwise to turn it back on.
  • With straight valve handles, the water is on when it’s parallel to the pipe and off when the valve is perpendicular to the pipe.

Look for a round, spigot-style valve or a quarter-turn ball valve.

  1. In older homes, the valve will usually be a round, spigot-style valve. You’ll see this style of valve on some newer homes too, but it’s pretty rare. Newer homes typically use a lever-style valve that won’t turn more than 90 degrees.
    • For round valves, turn the valve all the way clockwise to shut your water off, and all the way counterclockwise to open your water supply.
    • With lever valves, the water is off when it’s perpendicular to the pipe. Turn the lever so that it’s parallel to the pipe to turn the water back on.

Look around in the basement.

  1. Stroll down to the basement and orient yourself so that you’re facing whichever interior wall is closest to the street. Look at the bottom 1/3 of the wall for a pipe that feeds into your home. If it’s not there, look at the other adjacent walls. The valve will almost certainly be on top of this water supply pipe near the wall.
    • If your home hasn’t been worked on in a long time, this pipe is very likely going to look older than a lot of the piping in your basement.
    • This pipe will probably be copper or cast iron. In a newer home (or a home that has been recently renovated), this pipe may be rigid plastic or PVC.

Inspect the area around your water meter.

  1. If your home is super old and the pipe layout feeds into the ceiling or you can’t follow what’s going on, look for your water meter instead. The meter looks like a round, metal container in the middle of a pipe with a dial on top. If there is a valve right before or after the meter, that’s your shut-off valve.
    • The meter is normally in your basement, but it may be outdoors if you live in a warmer climate.
    • When your city started installing water meters, they would have put it right next to the shut-off valve on the supply pipe.

Look for a panel on the ground near the curb.

      Tips

      • Keep in mind that you’ll still have water in your pipes after you shut the water off, so turn a sink on to drain your system entirely once the valve is closed.
      • If you bought your home, the inspector should have shown you where the shut-off valve is. You can refer to your inspection report to find your shut-off valve.
