KOHLER GENUINE PART GP1068030 FILL VALVE FOR ONE-PIECE TOILETS

We have a Kohler Rialto toilet (2004 model). I learned that you need to disregard some of the instructions on the back of the gp1068030 package.Before you buy this product look inside your toilet tank and see if there is a refill tube that connects the fill valve to the flush valve. (If this refill tube is absent on your toilet, this is the correct fill valve for you-gp1068030) (the refill tube connects to a nipple at the top of the fill valve in some Kohler toilets)Hook up the fill valve according to the instructions, but don't worry about the refill tube-no water comes out of the nipple-the water fills the tank from below.It appears that the manufacturer used packaging/and directions for multiple fill valves-and the refill tube is not applicable to all kohler toilets.Hope this saves you some time.

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.

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.

This item is sold by Kohler, but is actually a Fluidmaster 747 valve which isn't a big deal except that:It doesn't come with a refill tube because it's manufactured not to use one. It has the nipple attachment for the tube, but the water pathway is literately internally blocked off.However, you can make it work by simply drilling out the plastic blocking the water pathway and reusing the old refill tube. If you do go the drill route, start with a small drill bit and work up so that you can control how much water is diverted to the tube.

I could not find a direct cross replacement number for the original valve that is no longer carried by Kohler as the toilet is not being made anymore. I searched a couple of supply houses that wanted over $120 for the original Fill valve number 100 7523. I took a chance at this would fit and it does. It is quieter filling than the original valve, install it, set the float level and it works perfectly. The original valve with a copper fill pipe lasted at least 15 years, so hopefully this one will last as long. It also arrived next day by prime shipping that was a plus also

Easy to install and fills the toilet super fast. Replaced the original Kohler fill valve which was temperamental ( sometimes would stick in the closed position ) and slow to fill.

This replacement fill valve is different than the original fill valve that came with the toilet. It is better in two ways: the fill tube diameter is larger, and it is easy to clean the valve diaphragm. The larger fill tube allows the toilet to fill faster. The easier to clean diaphragm may prevent the need to replace the valve in the future. The original valve was leaking, probably due to mineral build up. There was no obvious way to clean the valve, so I had to replace it.

The reason why I gave it a one was because it was missing the diaphragm that made the water shut off. So I had to use parts from my old valve. I fixed it and works as it should
