I have an older home that has a 14" rough-in toilet. My only choices seem to be: 1. Gerber DF-21-304 (Ultra Dual Flush/ Pressure Assist)
2. American Standard Cadet 3
3. Kohler Wellworth/ K-3433
4. Toto Guineviere/ Carrollton/ Vespin with the use of a Unift Adaptor.
Does anyone have experience with the Unifit Adaptor and how well it works? 14inch
