Review on Fluidmaster PRO45C High-performance Fill Valve by Devin Henry

Filling valve appears to be a regular product. Time will tell about its reliability. However, the tank damper plug is a terrible, cheap, poorly performing part. It's so light and thin that it won't close the water drain until the tank is empty. The previous unit, which I believe was Kohler original, had a sturdy baffle plate with an adjustable float attached to the chain so the flush volume could be adjusted to ensure adequate flushing without as much water to waste like the current one.
