I have a 40 year old American Standard one piece toilet.

I have replaced the rubber flapper that flips
up to flush, but I can not get it to always seal when it drops back down. I have put in 3 diffrent rubber units, wieghted it with paper clips, adjusted the chain and wiped the seat. How can I replacec the flush vvalve seat?

Thanks Kevin
