Check tank for fill line running from fill valve to overflow tube. It will be a 1/4 " line that allows the tank and bowl to fill. It should be connected from fill valve and connected at the top of overflow by a clip or hanger.

Check out the water level in tank to make sure it is filling to line on overflow or within 5/8" to top of overflow pipe.

Kohler 4634aa is running and I've already changed the flapper, could it be the valve?

Yes it could be valve just cause you changed the flapper doesnt mean that you stop water from filling in tank the valve that shuts water of can still be running the water will go down the bowl fill tube that is were the black tube goes that connects to the top of white pipe the simple whey to find out is just push down on black float and water will stop add in tank let off black ball and water should stop or just lift up on float arm and water should stop bend float arm if necessary.

Brand new kohler highline k 11499 96. Tank fills fine, but when I flush the toilet it lets about one fourth, if that, Water out of tank into bowl before canister float slams shut???

most modern flappers(what you call a canister float if i understand you correctly) have some type of adjustment feature which controls this.(like maybe rotating the flapper one way or the other) the old fashioned way was to take up the slack in the chain attached to the flapper so that when someone pushes the handle the flapper is pulled higher. make & model # or a pic would help me say w/certainty how yours works. just text me here if you need anything else and good luck:)

the tube that goes from the fill valve to the fill tube may not be installed correctly. the water must be going in the tube and not the tank. also it is a water conserving toilet so it uses less water also it is a comfort height toilet and to make it taller the bowl is extended so the water may seem even more shallow.

I have a Kohler Highline toilet that sputters

Did you try to lubricate with something waterproof to stop the squeak? How about grease? Petroleum jelly, something. Or how about a weight on the high side to balance it out as it goes up. A lead sinker or a penny. Hope this helps.

BRand new elongated Cimarron shoots water out of bowl durng flush

Is the fill line in the tank loose? Does it just shoot water into the tank itself? I had this issue until I realized the while fill tube is supposed to be pushed into the black cylinder/small plastic tube in the middle of the stopper assembly. After i pushed the line into the tube, the bowl would always only fill a little bit. Now it fills almost a 3rd of the way up the bowl and doesn't bubble during flushes.
