Review: This works perfectly the way it is. No need to drill or modify. This is the correct OEM part. - This is the correct replacement for the original part. In many cases, other fill valves will work fine, but because I have a low profile Kohler toilet, I wanted to just replace it with the oem part. This works exactly as it should. Some reviews state that this doesn't have a hole at the top like the original and you need to drill a hole. There is no need to do this. This works perfectly the way it is made.
Review: Perfect replacement for my old 1997 Rialto 1-piece toilet fill valve - 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.
