Ziosxin2 Inch Toilet Flush Valves, Toilet Repair Kit Dual Flush Valve Replacement Fit for One Piece Toilet Top Push Button Valve(One Piece Toilet 10.8" Height)

Seriously. How hard is it to print a page or two to explain what some of the adjustments are for? I would happily pay the extra 10 cents! It has a separate fill tube and differs quite a bit from the original Toto dual flush valve (discontinued) without any explanations as to functions of the different pieces.I was ultimately able to get this flush valve to function on my Toto 2 piece but the black gasket provided leaks and I had to disassemble the toilet a 2nd time to install the original gasket from Toto. I also used the Toto original bottom nut to secure to the tank as the one provided is harder to tighten. Since the 10.5" height is not as tall as the original Toto flush valve, I had to improvise and modify the flush buttons (see pictures). Picture shows the original Toto valve which does not have the fill column. I had to positions the fill column so it did not interfere with the tank mounting bolts. As an aside, I would never recommend a Toto two-piece dual flush toilet. I have had nothing but problems, it was extremely difficult to install and they discontinued building the fill valve!!!
