Review on Mansfield 211 Flush Valve - 11.5 inches - Universal Fit for Trip Levers by George Ahmed

The original 211 flush valve that came with the toilet was white but otherwise an exact replacement. Installation requires removing the tank, which is not difficult. However, the rubber washers on the screws that attach the cistern to the bowl crumble quite a bit when touched (this toilet is about 14 years old) and the black rubber that separates from the washers makes a real mess the hands. It would be a good idea to order three new rubber washers for the tank bolts (or just go to your local hardware store) before starting this project.
