Considering this, how do you adjust a fill valve?

To adjust this type of valve, you simply turn an adjustment screw located on the top of the valve. To raise the water level, turn the adjustment screw clockwise; to lower the water level, turn the screw counterclockwise. The water level must be below the top of the tank's overflow tube.

Also, can you adjust the water level in a toilet bowl? To adjust the water level in your toilet bowl, start by removing the tank lid and noting if the water level looks too high or low. Since the height of the float determines the water level, turn the screw on top of the fill valve 1 full rotation clockwise to raise the water or counterclockwise to lower it.
