My Toto G-MAX toilet flushing system is leaking a gallon per hour. The Toto tank says water level should be adjusted to 1/2 inch below the top of the overflow tube. But my tank's water level is even with the top of the tube. My G-MAX is green (as in the photo posted by Terry on Nov. 25, 2012). There is a white screw-head on the top that looks like it might be for adjustment.
