good flush valve

[sweep8]

I have replaced the fill valve in a Kohler Memoirs toilet several times and the FluidMaster units always stick at the bottom and the most recent one sticks at the top too. Is there a fill valve that will actually work in this toilet?

Assuming it will take a 'normal' fill valve, the Korky quietfill doesn't have an external moving float - it is internal (well, under a cover), so it can't catch on anything.
