Where is the Main Water Shut-Off Valve?

Posted on: September 5, 2017

Do you know where the main water shut-off valve is in your home? If you can’t answer that within five seconds, then you need to locate it and remember where in case there’s ever a serious leak. Otherwise, you could end up with a plumbing nightmare on your hands…

Where to Find the Main Water Shut-Off Valve

  • The shut-off valve is almost always located near the perimeter of your home. There’s no need to check the central portions of the house.
  • Forget the upstairs too, as shut-off valves are going to be located on the ground floor. For those with basements, it will usually be located here.

    Water lines usually run from the water main to the shut-off valve with no extra piping or detours. Therefore, if you know where you water main is, see where the shortest path to your home would be. The valve is more than likely located here.

  • During the purchase of a house, an inspection report is supplied. The location of your main water shut-off valve is labeled in this report (hopefully you’re organized so you have easy access to this report).
  • Do you know where the big panel is in your home (not the electrical panel)? This panel houses the shut-off valve since it’s illegal to cover it behind the wall.

Plumbing Fixture Shut-Off Valves

When a leak springs, it’s not always a slow drip. Sometimes the water will begin to rush out and start pooling on the floor of your home. Before you run to the main water shut-off valve, see if this fixture has its own personal shut-off valve.

  • Toilet – On the wall your toilet sits against, there will be a small valve. It is usually located below the bowl and should be turned gently (clockwise) to stop the flow of water.
  • Sink – Underneath the sink in the cabinet, there will be a small shut-off valve (similar to the toilet). During a pipe or faucet leak, turn the handle clockwise to suspend any water from leaking.
  • Washing Machine – Behind every washing machine should be two valves (and sometimes a lever). Both of these valves should be turned clockwise (or the lever should be switched the other way) in order to cease water from flowing. If you don’t see these valves (or lever), you may have to pull out the washer from the wall a bit.

Knowing how to stop the flow of water coming into your home can help prevent extensive water damage if there’s ever a serious leak.
