Does this tank come withe the internal valves and handles

Asked by: Doug
Yes, the tank comes fully loaded with the flush valve, float, and handle hardware. You just mount the tank with the 3 attached bolts and install the handle and water line.

Will this replace A. Kohler 4620 tank

Asked by: Nkh
Yes it does. I just put this tank on as a replacement for a 4620. Fit fine and flushes fine. I do not know why Kohler keeps telling people it will not work.

Does this fit a 4552?

Asked by: TM
I don;t know what a 4552 is. The reason I bought is because the touch less toilet I purchased started to go haywire and flush constantly on it's own. Sorry I could not answer your question.
