Knowing how to shut off your property’s water supply can be the difference between a minor repair and a major disaster. Make sure you — and anyone managing the property on your behalf — knows exactly what to do before an emergency happens.
Finding the Main Shut-Off Valve
The main water shut-off valve is typically located near the water meter, usually in the front yard or close to the street. In some cases it’s buried underground and may require digging to access. The valve itself is generally a large round or oval handle that controls water supply to the entire property.
Gate Valve vs. Ball Valve
There are two common types. Gate valves have a round, wheel-style handle that turns to open or close. Ball valves have a lever that moves 90 degrees to shut off the flow. Ball valves are faster and more reliable — if your property has an older gate valve that’s stiff or corroded, consider having it replaced.
How to Shut Off the Water
- Locate the main shut-off valve and identify the type
- Turn the handle or lever clockwise to close
- Use a wrench if the valve is stuck — don’t force it with your hands
- Confirm it’s fully closed by listening for running water or checking for pressure at a faucet
- If the valve can’t be located or isn’t functioning, contact a licensed plumber or your local water authority
Ongoing Maintenance Tips
- Test the valve periodically to confirm it operates smoothly
- Label it clearly so tenants or contractors can find it fast
- Keep a record of its location and any service history
- Properties with a well or septic system may require additional shutoff steps — know your setup
Keep emergency contact numbers accessible — your local water authority, a licensed plumber, and your property maintenance service. A 24/7 emergency maintenance relationship is particularly valuable when you can’t be on-site. Automatic water shutoff devices are also worth considering; they detect abnormal flow and cut the supply before significant damage occurs.
