I'm looking at two Toto Soiree toilets that appear identical except one has the red flapper with a black weight and inside the tank is a stamp that says 1.28gpf. The other has a pink flapper with no weight and doesn't have the 1.28gpf stamp.
Is there a difference between the two toilets? Is one older than the other? Is one flapper system better than the other? I'm guessing that the more likely answer is that these things are put together like a Dell computer, with whichever parts are available at the time.
(Our first Toto Soiree was delivered last week with a big chunk of the skirt broken off. While we were waiting for the replacement, I decided to glue the piece back on and install the toilet. I just want to make sure that the replacement toilet isn't an older/inferior model or something. It looks like we're going to end up with an extra toilet.)
