I have adjusted the float, but as mentioned above the float actually goes under water, but doesn't serve to shut off water to the tank.

Answer: 
The float shouldn't be "submerged" - that's why it's called a "float" it should be floating. Is it caught on the side of the tank? Does the height need to be adjusted to let it move up higher? The float should be at the same level as the top of your overflow. If it's lower, your tank will keep trying to fill.

Answer: 
It's kind of like a key; you have to turn it until it comes out of the slot. It fits pretty tight, but grip it firmly toward the bottom, then turn. You'll feel it when the flat part of the piston matches up with the straight slot.

Answer: 
Instructions can be found on U tube, but it's a simple fix. First check that the attached chain is hanging freely not binding if so undo and recheck for leak. If still leaking turn off water, flush and then remove the hose where it goes into center of the canister. Turn the center value counter clockwise and it will release. Then remove the canister after removing the chain. Replace the seal.

I have the same issue, the yellow stopper continually comes unseated. Kohler, it would be useful for you to develop a solution to the yellow stopper in the replacement repair kit.

Answer: 
This system that Kohler came up with is junk. I have the same problem. I had to replace the top piece myself. Unless it is less than one year old, Kohler won't replace under warranty .
I have toilets that are 17+ years with different flushing system and have no problems. I bought a Kohler and and having problems at less than 2 years.

Will replacing this part, GP1229656 AquaPiston keep the canister from rotating and thus preventing a good seal at the flush valve?

Answer: 
Check that the chain which pulls up the canister is not binding. This would cause it to set at an angle when the flush handle is released. Make sure your piston is seated and not loose. The repair valve kit would be needed only if yours is loose or you have older style which allows the hose to slip out and not fill the bowl completely. Always check the bottom seal when apart.

Answer: 
First thing to try is make sure the chain and chain catch loop are not getting caught up on any other parts. Vaseline on the chain can sometimes help in very small amounts. Last resort replace the seal. Seal replacement video below

Rated 4.0 out of 5 by 10 reviewers.
Rated 1.0 out of 5.0 by Junk I don't know why Kohler came up with poor design of a flushing system. The"Canister" is the worst flusher I have ever seen. I bought a new Kohler toilet with this system thinking the Kohler had the name and reputation . However this system broke after less then 2 years. I have other brand name toilets that 17+ years and are still working great. Contacted customer service. They only have a 1 yr. warranty . I would think twice before buying my next Kohler toilet. Not impressed. May 20, 2016
Rated 1.0 out of 5.0 by would not buy this kohler toilet again! i purchased this toilet at your store, and not even a year old i had to repair it!? great flush and water saver, but being a plumber i will not install these anymore! hope i don't get call backs because of these whimpy plastic parts. April 20, 2016
Rated 5.0 out of 5.0 by Fixed a problem The original design was such that the hose would slip off the top and cause water to splash out the tank. What a nusance! Now this is a better design. April 20, 2016
Rated 5.0 out of 5.0 by good purchase Very easy to put together ,you just have to be gentle and know what you are doing, I think everybody can do that, the instructions were clear and well explain ,I really like it. November 4, 2014

Rated 5.0 out of 5.0 by Works perfectly! Hard to find Kohler flush valve replacement parts in other stores. Thanks Home Depot! December 15, 2015
Rated 5.0 out of 5.0 by The way the part should have been engineered to begin with! If you have a Kohler toilet then do yourself a favor and replace that brittle plastic part asap. The installation was easy (although a bit scary seeing as how the entire assembly is plastic and brittle). Just twist the old center flush valve out counter clockwise and install the new one. The old one was or felt a bit stuck so take care not to ruin the housing. I did have to apply a fair amount of pressure to get the old one out. Price wise this new and improved part should be much cheaper seeing as how the original part can snap so easily. This part does add more time to filling the tank and quiets the filling up a bit more than the previous part. March 24, 2015
