Kohler toilet w/ piston water flush 2 step doesn't flush even at the 1st step, let alone at the holding the handle down for the 2nd step. We woke up to the toilet leaking water into the bowl.

Pro tip: The Fluidmaster flapper we show includes a plastic cup that allows you to adjust the length of time the flapper stays open. It’s for toilets that use 3.5 gallons or less for a flush.
