I replaced the Fluidmaster valve this morning, and the flapper last
week. The food coloring test is still showing up at the bottom of the
bowl after about 15 min. Not sure what else to do. I am considering
trying the Korky kit that supposedly "repairs" the flapper by using a
ring that is siliconed in place under it. I suppose if that doesn't
work, I'll have to pull off the tank and replace those parts.


Let it fill, then turn off the water supply. If the tank leaks down,
it's the flapper. If it doesn't leak down, its the valve.
