I have two Kohler 1.6 gal. flush toilets 1 1/2 yrs. Old. They bth just recently started to take excessive time to fill. There is some instructions that say to clean and flush the system but does not tell you how to do it?

See the images below if you tell us which one is your fill valve then we will tell you how to clean and flush the system, Thanks.
