I just installed my 1st 1.28 gallon toilet. It was a Toto drake. Now I'm thinking they may have screwed up with the wrong tank. It flushed awesome with just water. Did the drake go to 1.28 or did they send the wrong tank? The customer did not pick 1.28 they just picked the toilet and I picked it up from the supply house when it came in. I guess I'll call the supply house monday and get to the bottom of it.
We did not install a toilet seat bidet........so sad so sad
