Hi, Scott! Thank you for your question. The Delta C41908D-WH toilet tank is not insulated. Best Regards, Rosanna
It does not have a flapper inside.
It takes about the same amount of time that it would take to move a handle down to flush. I push the button until it bottoms out and let go. It flushes well. If you only push the button half way down, you won't get a good flush. As for holding the button down several seconds, I haven't had to do that for a good flush.
You have been lied to this is 1.28 gallons total capacity use an empty milk jug prove me wrong or right , ( I'm right)
