📌Under sinks Look for small valves connected to the water lines.
📌Behind toilets Usually a single valve near the floor.
📌Laundry closets Especially for washer shut-offs.
📌Mechanical or utility closets Main shut-off valves are often here.

How to Use Your Shut-Off Valve – Once you’ve located the valve, here’s how to operate it:
For Fixture Valves:
