Adjusting attic tank ball valve?

[johnnyapple]

Can this be done? The level of the water is worryingly high, and its not supposed to be like that. Can the ball valve be adjusted so the level of the water is lower?

If you bend the bar downwards you should have the desired effect

You can bend the ballcock arm to adjust the level of water that stops the flow. But don't break it!

Which part is the 'arm'?

Which part is the 'arm'?

It is the metal leg that connects the plastic ball to the valve.

Christmas time is the wrong time to try to bend a ball valve arm if the overflow pipe is not dripping.
Plumbers also like a break.

Some recently made brass ball valve arms are very brittle and will snap
