Safety First

Adjust the Float
Most toilets have a float. It controls the water level. Find the float inside the tank. It might be a ball or a cup.
Ball Float
If you see a ball, it is a ball float. Use a screwdriver. Turn the screw on top of the fill valve. Turn it to the right to lower the level. Turn it to the left to raise the level.
Cup Float
If you see a cup, it is a cup float. Find the metal rod. Squeeze the clip on the rod. Slide the float up or down. Up for more water. Down for less water.
Test the Flush
Turn the water back on. Flush the toilet. Check the water level. Did it change? If not, adjust again.
Put the Lid Back
Once you are happy, put the lid back. Be careful. Make sure it fits well.
