I have a question regarding the downpipe valve adjustment.
The manual states “To raise the water level in the overflow box, rotate the valve clockwise” and “To lower the water level in the overflow box, rotate the valve anti-clockwise”
What exactly is happening when the valve is turned? Does something raise or lower? Does something open and close?
