I took apart the current fill valve and noticed that the 3 gaskets as deteriorating ... wondering if I can source some replacement gaskets. On another Toto toilet model that used a Gmax fill valve ... I was able to substitute parts from a Korky version. Hence, I'm wondering if I can do the same with the Cyclone. I don't see a similar design from Korky. I did find a similar Fluidmaster version (design) but the top looks different. Any suggestions? Thank you.
Hey, wait a minute.

This is awkward, but...
