Review: Another helpful Tip! - This is a genuine KOHLER replacement part that is KOHLER quality, not some after market cheap copy such as a flapper I ordered when I was not paying attention! Thanks to TekLord's helpful instructions (see his comments) the installation went smoothly, but I could not have done it without his help!! My toilet is once again working the way it did when it was new, however I did learn one other tip that I'll pass on to you. I had adjusted the water level previously by turning the adjusting screw Clockwise so that it would allow a higher water level in the tank and consequently more water per flush. As I found out....It was a bad idea, as it caused me some problems. After installing the flush valve I shut the water line off at the wall so that I could tell if there was any leakage at all from the new Flush valve assembly. As I sat there watching it I saw the water level drop slowly to a certain point and then stop. I also noticed a thin stream of water coming from the fill tube running down the inside of the overflow pipe. I thought , "GREAT! Now I have to replace the the fill valve! :^( I went on line to see if I could find some instructions for checking the fill valve. I did, and in them I found that the tip of the water tube that runs from the fill valve has to be above the tank water level otherwise it syphons water back into the overflow. so I looked at the overflow tube again and found the proper water level mark...adjusted the water level screw counterclockwise to drop the water level to that mark and Voilà, the water stopped syphoning! I shut the water supply line off and waited 3 hours to check the tank water level. It stayed right at the level of the mark! YES !!!!!! :^)

### ⭐⭐⭐⭐⭐ Kohler 1044458 Flush Valve Kit
*by M***K on August 14, 2025*

It's expensive but probably the most reasonable priced of all I found. When I received it the gasket was very warm and soft and Squishy so it was very easy to install this thing. Online you may see that people complain that it was very difficult to install.
