To close a water supply valve that's a ball valve, turn it a quarter turn clockwise.
Based on the provided reference, closing a water supply valve that utilizes a ball valve involves a simple, quarter-turn action. Let's break down the process:
Understanding the Ball Valve
A ball valve is a type of shut-off valve that controls the flow of a liquid or gas using a rotating ball with a bore. When the bore is aligned with the flow path, the valve is open, and when it's turned 90 degrees (a quarter turn), the ball blocks the flow, closing the valve.
Steps to Close a Ball Valve on a Water Supply
- Locate the Water Supply Valve: Typically found on the inlet water manifold or near the water meter.
- Identify the Ball Valve: Look for a valve with a handle. The handle's position usually indicates the valve's state. If the handle is parallel to the pipe, the valve is open. If the handle is perpendicular to the pipe, the valve is closed.
- Turn the Valve: Grip the handle and turn it a quarter turn (90 degrees) in a clockwise direction. This will move the handle perpendicular to the pipe.
Additional Considerations
- Valve Location: Familiarize yourself with the location of the main water shut-off valve for your home before an emergency occurs. Common locations include the basement, garage, or outside near the water meter.
- Stuck Valves: If the valve is difficult to turn, don't force it. Apply penetrating oil and try again after a few minutes. If it's still stuck, consult a plumber.
- Partial Closure: While partially closing a ball valve may seem like a way to reduce flow, it can damage the valve over time. It's best to either fully open or fully close it.
In summary, closing a water supply valve that utilizes a ball valve is achieved by turning the handle a quarter turn clockwise until it is perpendicular to the pipe.
