What Size Flapper Do I Need?
You discovered there are some differences in flush valve systems and that toilets sizes can vary. An easy reference is to look at the size of the flush valve drain opening in the bottom of the tank. If it’s about the size of an orange or baseball, you need a 2 inch seal. If it looks more like the size of a grapefruit or softball, you need a jumbo 3 inch seal. You can also measure the flush valve opening to determine what flapper size you need.
