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.
Review: Do the job well!!! - * Update (05/23/2014) - As an experiment, I've just swapped the plastic riser with the old copper riser. The connector is perfectly fit...It is quiet like new...I highly recommend to use the old copper...Definitely, you need to clean calcium residue on the connector's surface... I still give the product five stars. If you just buy rubber rings and valves at some websites, the cost (including shipping) is almost the same with valve. * Kohler replaces 1018282 for 1-piece toilet K-3388 with this plastic 1068030 fill value. While both of them almost the same, the original OEM has riser made of copper so am little skeptical about it. The price is 1/3 of copper part but it is made by Kohler as a replacement so I gives it a try. Pro: * FIll time is much faster as someone mentioned. I guess the bigger riser does the job. * Cheap * Made by Kohler to meet its specification. So it perfectly fits. The fill valve is really compact with 10" height. Generic fill values will not fit. * It is easy to assemble. It took me around 20-25min to replace the fill value and flapper. Con: * The original copper OEM is more quiet. I guess the copper part helps it. I did adjust water flow-in, but it did not help...Someone suggest to swap the copper riser...I might try it latter. Other thought about copper riser, it is not about durability since the rubber ring and value will break first before other plastic parts. It really makes a little bit more quiet especially at night...

### ⭐⭐⭐⭐⭐ No Tube Required !!!
*by J***H on December 4, 2024*

This was a simple installation. However, we were totally baffled by the fill tube, which I replaced from the old unit. While the installation worked great, the water was filling from the bottom and not via the tube. After checking numerous reviews……it turns out someone had called Kohler and they said the tube was no longer required…….there is a nipple on top for a connection….and another reviewer said if you drill it out, it will work. Anyway, the install took 10 minutes and the research took an hour. It works great and is filling the tank in about 1/3 of the time it took prior to the upgrade.
