Review on Mansfield 211 Flush Valve - 11.5 inches - Universal Fit for Trip Levers by Joel Briggs

I needed to replace the red valve seal on my old 211 mechanism. I tried 2 different ones bought online which should have worked, they were from a different manufacturer and claimed they were suitable for 'Mansfield 211'. They don't fit 100%. Still full of holes. There was nothing left but to buy the original, unfortunately I had to buy the whole mechanism, but since only the reading seal is 6-7, then paying 11 dollars for it is not so much. And it worked! No more wasted water.
