How to Shut Off Water to Your Home Safely
Use a fixture shutoff for an isolated leak when it is accessible and working. Use the home’s main shutoff for a larger or unknown supply leak. Never enter an unsafe area or force a damaged valve.
Start with the closest working shutoff
A toilet, sink, or appliance may have a nearby shutoff valve. For a leak clearly isolated to that fixture, closing the local valve can stop flow without shutting down the whole home.
Use the main shutoff for a larger supply leak
Main shutoff locations vary by home. Common locations include where the water service enters the building, a basement or crawlspace, a garage, or an exterior meter area. Learn the location before an emergency and label it for household members.
Do not force a stuck or damaged valve
Excess force can break an older valve or piping. If the valve will not move normally, is corroded, or is surrounded by unsafe conditions, stop and request professional help.
After the water is off
Confirm that flow is slowing at the affected fixture, then arrange evaluation of the cause. Turning water back on before a failed pipe or connection is repaired can restart the leak.
