The original bolts holding the tank to the stool were corroded and the washers all but deteriorated to black smudges in the tank. The new washers are black and I had a problem getting one of them to seal. I finally added some teflon plumber's paste between the washer and the tank to stop the leak.

Don't Waste Your Time or Money
Would Not RecommendThis flush valve is shorter than previous models so the toilet tank will not hold nearly as much water. Don't buy it........I'm dissappointed in Fluidmaster for even selling this product.

Reliable and straightforward to install
Would RecommendI bought this to replace the overly complex, failing flush valve in my American Standard Champion toilet. Installation was straightforward, although a little time consuming. All the hardware I needed was provided, and no special tools were necessary as the very large nut is only meant to be hand tightened.
