To turn off a water supply using a ball valve, you rotate it a quarter turn.
Based on the provided YouTube video titled "How to Locate and Operate Your Water Valve", here's a breakdown of how to turn off your water supply, focusing on ball valves which are the type discussed in the video:
Turning Off Water with a Ball Valve
The video explains that ball valves, common in water supply systems, are operated by a handle. The handle, when aligned with the pipe, indicates the valve is open, allowing water to flow. When turning off water, rotate the handle a quarter turn (90 degrees), so the handle is perpendicular to the pipe. This position closes the valve, stopping the water flow. It's important to turn the valve slowly.
| Action | Ball Valve Position | Water Flow |
|---|---|---|
| Open | Handle in-line with the pipe | Water flows |
| Close | Handle perpendicular to the pipe | Water stopped |
Key Points:
- Quarter Turn: Ball valves only require a quarter turn to fully open or close.
- Slow Operation: The video emphasizes opening valves slowly to prevent damage.
- Handle Position: The handle's position visually indicates whether the valve is open (handle aligned with the pipe) or closed (handle perpendicular to the pipe).
By following these instructions, you can effectively and safely turn off your water supply using a ball valve.
