Test In-Unit Water Shutoff Valve

Locate your unit's main water shutoff valve — in condos and townhouses it's often under the kitchen sink, in a utility closet, or behind the washing machine. Slowly turn it fully clockwise (closed), then counterclockwise (open) to confirm it moves freely. A valve that hasn't been exercised in years can seize open and fail to shut off during an emergency. Also locate any secondary shutoffs under sinks and toilets — turn each one fully and back. In a burst pipe or appliance failure, cutting water within seconds prevents tens of thousands in water damage.
