    I replaced it with a Korky 528. The Korky is a little quieter.

    I have had my Cimarron since April of 2012 and it has the 400A fill valve. It is very quiet and doesn't leak. I had to rinse out the cap a few times because we have VERY hard water and the sediment gets kicked up in the well. But other than that, it's great!

    The Kohler Fluidmaster has a rubber "flow/noise" reducer stuck in the bottom of it. That will get obstructed and restrict the flow, and when it happens the restrictor has to be removed for normal operation. I have not installed any American Standard toilets that had Fluidmasters in them. I do not like the Korky fill valve and use Fluidmasters exclusivley.

    The 400A has no bowl refill adjustment. It's a basic fill valve that is easy to adjust for tank shutoff, but no adjustment for bowl refill.
    It can be louder than other fill valves.
    If the fill tube is not daylighted above the overflow tube, it can siphon water from the tank. This can cause constant tank refill. It does come with instructions and a part for that, and it must be used.

    Because bowl refill is not adjustable, it can waste a gallon or two of water down the drain during refill. That is sometimes why it can take so long to refill after a flush.

    Most consumers would have no idea that this valve wastes so much water. It's going down the drain, and just adds to their water bill.

    It seems that the Fluidmaster doesn't fill as quick as the Korky does.
