I have heard that I need Kohler brand parts to repair my toilet. Is there any reason a universal fill valve will not fit. The current is a Kohler fluidmaster black shank GP1083167. I want to know if I can use the Fluidmaster 400a universal instead. It’s cheaper and the store was out of the Kohler brand.
simplymyself yes, you could in theory change it with a universal valve. The issues are the fill ratio with the tank. Take a look on here for a better explanation. There are multiple other brands like this that are usable in the Kohler tank. A good home improvement store can most certainly “hook” you up.
