KOHLER GENUINE PART GP1068030 FILL VALVE FOR ONE-PIECE TOILETS

My old 17 years oldKholer stopped working correctly; it took almost half an hour to fill the water tank. I realized the problem was the filling device. After trying to repair it with many cused words, banging on it with an hammer, I figured I need to replace it. Since the part number was discontinued, it wasnt clear what I need to replace the old rusty part. I just measured the height lf the tank and found this one. Very good product for the price. Work well. Took my 10 minutes in total. Now my old toilet is working correctly and dont have to use the sink when waiting for toilet to fill up. Yhe wife is happier now.

Me encantó el producto, porque sl ser una refacción original, es muy fácil de intercambiar, y funciona de maravilla, aunque el mueble ya tiene 20 años en uso.

I was skeptical about this fill valve as it looked very different and cheap (plastic) compare to my original part (all metal) in the toilet. After doing much research online and lack of other alternatives, I have decided to give it a try. Boy, am I glad I did that, this replacement is so easy to install and worked so much better than the original part. It took only 20 min to replace the part, most of the time was spent on emptying the water from the tank. The water height adjustment was extremely easy, just turn a screw at the top of the unit with a Philip screw driver to lower or raise the water level (the instruction did not mention that feature by the way). The unit does make a bit more noise than the original because it was made with plastic rather than metal. The original part made so little noise when filling which made you wonder if the water was actually going. This one you could hear it going but still a lot quieter than the other toilets that require a tube to fill. Now, here comes the good part, the new unit only took 35 sec to fill the tank whereas the original part took 1min 5 sec when it was new. At the end, the old unit took 2 mins to fill even after I tried flushing it. Some reviews mentioned about drilling a hole for the tube connection. I am not sure this part was meant for toilet requiring a fill tube. The drilling was not needed in my case, because my toilet never used a fill tube to begin with. That's why it was so quiet. The water was supposed to come out at the BOTTOM of the unit directly into the water tank to lesson the noise. This unit can be flushed easily as a routine maintenance. All it takes is one twist of the fill valve and it comes apart for flushing (check out the video in Kohler's official website). The old metal unit was mush harder to do. Since this unit is made with plastic so I don't expect scale to build up inside the unit to plug up the water supply and slow down the fill time like the metal unit would. I am glad I bought this unit.

Fit my discontinued Kohler Rialto toilet. Replacement was easy.

This fill valve is for a low profile Kohler toilet. The original valve passed continuously after about five years. The valve rubber diaphragm in the valve wore out. Unfortunately, I could not find a replacement part. The rest of the original valve was still okay. That being said, I found adjusting the water fill level somewhat fussy both on the original and on the identical replacement. Take note that the price for the Kohler fill valve replacement is 2x to 3x generic toilet fill valve replacements, but I wasn't sure they would fit in the low profile toilet tank. Bottom line: After replacing the original fill valve with an identical, expensive replacement one, the toilet is working okay again.
