There is no reason to change tank design.
One thing that determines how well the water drops, is the height.
They did change the flush valve flapper to release less water.
They also have a new part number on the bowl.
I will be interested to see why they changed the bowl numbering and how it's changed.
There is a certain part of my business that is helping consumers buy green products.
I also have the one-piece Ultramax's in the E-Max flush.
