Hey John,
How's it going. I'm throwing a replacement cap assembly in the mail for you.
It's the easiest fix I know for these.

: The fill valve in my Toto toilet will not shut off when the tank is full and water will continue to run and overflow into the overflow tube. I checked the float and it seems to be operating correctly. If you just tap the top of the fill valve assembly it shuts off?
