The short answer

Locate the Main Shutoff Valve

The main shutoff valve controls all water flowing into your house. It is typically located where the water supply pipe enters the building, which could be in a basement, crawlspace, utility closet, or near the water heater. In warmer climates, it might be outside near the foundation.

Look for a round wheel handle or a straight lever handle. A wheel handle closes by turning clockwise, while a lever handle closes when it is perpendicular to the pipe. If you have a well, check near the pressure tank. If you live in Kirkland, keep the location written down and show every adult in your home.

Turn the Valve Clockwise

For a wheel handle, grip the wheel and turn it clockwise until it stops. You may need to use moderate force, but if it resists, do not force it, as that can break the valve. A lever handle should be turned until it is at a right angle to the pipe.

After closing, test by turning on a faucet inside the house. If water stops running, the valve is closed. If water continues, the valve may be faulty, or you may have turned the wrong valve. In that case, close any other valves you find and call a plumber.

Remember that turning off the main valve shuts off water to the entire house, including toilets and sinks. Make sure everyone in the home knows you are doing this, especially if someone is using water at the moment.

  • Turn clockwise for wheel handles.
  • Lever handles close when perpendicular to the pipe.
  • Test with a faucet after closing.
  • Do not force a stuck valve, call a plumber.
  • If you cannot find the valve, contact your water utility.

What Counts as an Emergency

You should shut off the water immediately if you see a burst pipe, a major leak, or water spraying from a connection. Also shut it off if you hear the sound of rushing water and see water pooling under a sink or appliance. Acting fast limits damage to floors, walls, and belongings.

For a minor drip, you can often use the shutoff valve under the sink or behind the toilet instead of the main valve. But if you are unsure of the source or the leak is spreading, close the main valve to be safe. After you stop the water, you can assess the damage and decide next steps.

After You Turn off the Water

Once the water is off, open a few faucets to drain the remaining water in the pipes. This reduces pressure and helps you see where the leak is coming from. Place buckets or towels under the leak to catch drips, and move valuables away from the affected area.

Check for standing water and begin drying the area with fans or a wet-dry vacuum if you have one. For significant water damage, you may want to contact local water damage pros for an inspection. They can help assess structural damage and begin drying and cleanup. If you live in Kirkland, keep your shutoff valve location written down for future reference.

When to Call a Plumber or Pros

If you cannot find the shutoff valve or it will not turn, call a plumber right away. A plumber can also repair a broken valve or a burst pipe. For water that has already soaked into floors, walls, or drywall, you may need water damage pros to handle extraction and drying.

Do not attempt to repair a leaking pipe yourself if you are not comfortable. A small mistake can cause worse damage. For emergencies like a major leak, you can also contact your water utility to shut off water from the street, but that may take time. Acting quickly is important to minimize damage.

If you have insurance, check your policy to see if it covers water damage. Policies vary, and your insurer decides what is covered. Take photos of the damage before any cleanup, as that can help with a claim.

Frequently asked questions

What if the main shutoff valve is stuck?

Do not force it, as that can break the valve and cause a worse leak. Call a plumber to inspect and replace it. In the meantime, you can use the shutoff valve under the sink or behind the toilet to stop water in that area, or contact your water utility to shut off water at the street.

Can I turn off the water to just one appliance?

Yes, most appliances like washing machines, dishwashers, and toilets have their own shutoff valves. Look for a small valve on the supply line, often behind the appliance. Turn it clockwise to close. This is useful for minor repairs, but for a major leak, use the main shutoff.

How do I know if I turned the right valve?

After closing the valve, turn on a faucet inside the house. If water stops flowing, you found the right one. If water continues, you may have closed a branch valve, not the main. Check for other valves along the pipe and close them as well. If you are unsure, call a plumber.
