Answer: 
The top disc installs by turning about 1/8 of a turn in the aqua piston. This locks everything in place and makes it impossible to come off while in use. Sounds like you might not be turning the top disc to lock it in place.

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.

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.

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

This product works great but it seems like the yellow seal could be sold separately from the tower and chain. Both of those parts are more durable. In the case of my daughter's toilet, neither of them needed to be replaced but since these parts came, I replaced the tower along with the yellow flexible seal but didn't replace the chain. I would rather see the two seals, this one and the one that goes at the bottom to seal the flush valve packaged together since they are the two parts that are the most likely to need replacing. Still, if one needs the yellow seal, one has to get this kit. It does work, so I do recommend it.

Rated 5 out of 5 by from New Style Much Better Than The Old One After my second old style valve broke, I was surprised that Home Depot is stocking this new design valve. Just as easy to install, does not allow water to spray out of tube, and I think it fills faster and is not as noisy as the old style. Time will tell, but so far I think this is a much better designed valve.

One downside, the kit version was not available for a month+ that included all the parts I needed. I could order the pieces for more money and have it that week for pickup
