Where is the correct height for a toilet tank?

How to calculate the volume of a toilet tank?
Calculate the toilet cistern or tank volume in inches: Width X Depth X Water_Height = TTWV Cu-In = Toilet Tank Water Volume in cubc inches. If you are in the U.S., convert the cubic inches to gallons by dividing: Tank Water Volume (U.S. Gallons) = TTWV Cu-In / 231 That’s the tank “full” volume.
How much water is supposed to be in a toilet tank?
From 1982 to 1993, many toilets were made to use 3.5 gallons per flush. Federal guidelines require newer toilets to use less water, with 1.6 gallons being the maximum legal amount per flush. But water-efficient toilets can use even less at 1.28 gallons or less per flush.

How do you raise the water level in a toilet tank?
Push down by hand on the ball float that is attached to the outer end of the rod. If you hear water run, use the adjustment screw at the inner end of the rod to raise the water level in the tank. Turn the vertical adjuster screw at the top of the valve where the rod connects counterclockwise to raise the water level.
